There is a knocking noise in the steering rack on Renault Logan, what should I do?

For more than ten years, Renault Logan has been successfully operated on Russian roads. High reliability, maintainability and cost have won the attention of a huge number of car enthusiasts. During all this time, Logan owners have accumulated considerable experience in servicing and repairing various parts and mechanisms of this car. This also applies to the steering, namely the steering rack, because symptoms in the form of knocks and crunches on cars of different years appear periodically.

In the video below you can hear a similar knocking sound.

Renault Logan steering rack repair

The steering rack is a mechanism that ensures the transmission of forces from the steering wheel to the rods of each wheel.
In other words, this is a device with which the front wheels rotate in the direction in which the steering wheel turns. The Renault Logan control rack is a reliable unit that rarely undergoes any damage or deformation. However, constant loads can damage the rack, which will lead to its repair, adjustment or replacement.

Brief description of the steering device

Before starting any actions to service the machine, it’s a good idea to get to know its main components and how they work. The bulk of French brand cars are equipped with a hydraulic booster control system

.
It includes
:

• steering column;
• rod ends;
• steering knuckles with hub;
• hydraulic booster and injection lines;
• fluid pressure sensor.

For ease of assembly, each tip has a right one - I, a left one - II. The design is made according to the “gear-rack” scheme. The mechanism connection is located in a special housing and is regulated by a special plug when the product is assembled at the factory. In the future, the gap between the parts cannot be changed.

DIY steering rack diagnostics and repair

The steering rack transmits rotation from the steering wheel to the wheels. It affects handling, and any malfunction of this unit makes the car less obedient. Steering rack elements are subject to natural wear and tear, and they are also subject to shock loads from driving on rough roads. This leads to the fact that by the mileage of 200–250 thousand km, the steering rack of almost every car requires replacement or repair.

Steering rack Logan components

Let's look at the components:

• Steering rods and ends responsible for turning the wheels are attached to the retractable mechanisms of the part.
• A toothed bar with gears is responsible for transmitting force from the steering wheel to the rods and controls the wheelset.
• The housing (crankcase) is a component made of aluminum; it contains all the main rack mechanisms.
• The spring system ensures a tight fit of the rack to the gears, and also eliminates the steering wheel from free movement and play.
• Limiters regulate the maximum value of steering wheel turns to the left and right.
• Bearings - used for ease of manipulation when turning the rack.

Typical Renault Logan steering rack faults and their symptoms

According to statistics, Logan's weak point

on the chassis - these are the front hub bearings.
But at the same time, frequent failures of thrust bushings due to unsatisfactory road surfaces have been noted. This is determined by the following criteria
:

• vibration;
• strong knocking sound when driving on an uneven surface;
• increased play when turning the steering wheel (especially on the right).

Some “masters” solve this issue by simply tightening the adjusting plug. It has already been written about above: the plant, anticipating such a situation, categorically prohibits doing this. If the worm gear is excessively clamped, intensive wear of the teeth begins, which can lead to undesirable consequences.

What malfunctions may occur

During the operation of the car, various malfunctions may occur:

1. Stiff rotation of the steering wheel. This indicates that the rack has been damaged by corrosion. In this case, the only way out is to disassemble the unit, clean it from traces of corrosion and restore the rod. If the problem is serious, some parts may need to be replaced.
2. Knocks are heard in the area of ​​the steering rack (mainly when the steering wheel is rotated). This sound is characteristic of damage to the worm gear bushing. In this case, the only way out is to replace it. To carry out the work, it is necessary to prepare a repair kit in advance.
3. The appearance of a leak and a decrease in the liquid level in the tank. The reason for such a breakdown is a violation of the integrity of the seals (this is possible due to corrosion). Adjustments or repairs will not solve the situation. The faulty unit needs to be replaced.
4. “Bite” of the steering wheel rod. This breakdown occurs due to wear of the teeth of the worm pair. The solution to the problem is to replace the components. When choosing a repair kit, it is better to purchase original spare parts.
5. Steering wheel play. This problem is caused by a broken rod. The solution is to repair or replace the unit.

Signs of a faulty steering rack

• Unpleasant knocking vibration that reverberates through the steering wheel
• There is play when turning the steering wheel
• Oil leaks appeared
• Turning the car now requires more effort than usual

If you have one of these signs, we advise you to first read this article.

If they are not suitable for you, then this indicates that the rail still needs to be disassembled and worn components replaced.

Basic troubleshooting methods

It is not difficult to carry out work on troubleshooting the steering rack yourself; the main thing is to determine the cause of the breakdown. On the Internet you can find many photos and videos that tell in detail how to replace this or that element of the device. Basic troubleshooting methods:

• When the steering wheel is rotated, characteristic knocking noises are heard in the part where the steering rack is located. This indicates damage to the worm gear bushing. The unit cannot be repaired but requires replacement. You can make a new part yourself if you have a drawing of the device and the correct choice of material. The bushing can be bronze, plastic, etc. The cost of a homemade element will be much cheaper than a purchased one. A BMW bushing with catalog number 7820 023 188 is suitable for Logans.

Important ! The manufacturer suggests replacing the entire steering rack assembly. But such repairs will cost a lot of money, especially when installing the original. The cost of the analogue is half that - 10-11 thousand rubles. Not every car owner is willing to pay such a price.

Replacement is carried out as follows:

1. The vehicle is placed on a jack from the right wheel side.
2. The steering tip nut is unscrewed and dismantled.
3. The steering wheel position is set all the way to the left, and the boot clamps are cut off.

1. The boot is removed from the rack.
2. It takes two people to remove the tie rod: one pulls it down, the other adjusts the key after each turn.
3. The steering wheel is set to the extreme right position. Now you can see the bushing normally.

Before installing a new homemade bushing, you need to sharpen it, correcting the size. Before installing the part, you should lubricate the seat. Assembly is performed in reverse order.

• Increased play in the steering wheel is most often caused by wear of the teeth of the worm pair. The problem is solved by restoring or replacing faulty components.
• The appearance of traces of leakage and low fluid level in the tank. The reason is wear, breakage or rust on the seals. You should correctly select and buy new parts and install them to replace the damaged ones.

• The cause of heavy rotation of the steering wheel can be complete corrosion of the steering rack. It is necessary to disassemble the device, clean it from rust and carry out additional work to restore the rod.

Logan steering rack - part adjustment

Adjusting the Renault Logan steering rack eliminates the overall steering system from backlash and knocking, which become the main causes and symptoms of malfunction. In the process of debugging the steering rack, special wrenches and screwdrivers are used to quickly get to the desired nut, with which the part is adjusted.

Since the nut is under the hood, the car in a car service is raised in order to open the steering column space for the technician. An alternative is to use a garage pit.

During the first adjustment, the nut can be closed with a special plug, which can be easily removed by prying it off with a screwdriver.

If the element is excessively “stuck”, i.e. its movement is not amenable to an ordinary wrench; craftsmen resort to the help of a hammer and a special lubricant, which facilitates the movement of the nut along the thread.

basic information

Power steering or, as it is abbreviated as power steering, is a hydraulic system of a vehicle, part of the steering mechanism, which is designed to facilitate control of the direction of movement of the vehicle while maintaining the necessary feedback, as well as ensuring stability of operation and unambiguity of the specified trajectory. Power steering is one of the most important steering components of any vehicle. The main purpose of power steering is to create lateral forces when turning the steering wheel due to the presence of an electric drive.

Renault Logan power steering pump

Experienced motorists highlight several main advantages of power steering on Renault Logan cars, such as:

• High information content;
• Low fuel costs;
• Convenience of adjusting the technical characteristics of the manual;
• High level of reliability.

Power steering for Renault Logan cars includes the following basic elements:

• Cylinder. With the help of a cylinder, fluid pressure is converted into movement of the piston and rod.
• Pump. Thanks to this device, the circulation of functioning fluid and pressure is ensured.
• Oil that transmits resistance from the pump to the cylinder and also lubricates all pairs.
• with distributor. With its help, an air flow is provided that directs the oil to the required cylinder or back to the tank.

It is considered a high-tech unit that pumps fluid, under a certain pressure, into the steering mechanism and creates fluid circulation in the steering mechanism. Today, the vane power steering pump is quite common, due to its low sensitivity to surface wear and high efficiency.

Installing power steering on a Renault Logan is simply necessary, because with the help of this equipment the steering wheel is turned. And thanks to the torsion, torque is transmitted to the steering system, while simultaneously measuring the twist and angle of rotation of this wheel. To carry out such measurements, special sensors are used, and the received information is transmitted to the hydraulic booster. This is how the hydraulic booster is maintained in the required mode. After this, the torque goes to the steering mechanism and the drive wheels of the car. The torque is provided by an electronic control circuit with the help of maximum functioning of the car engine.

Repairing the pump

Due to active use and heavy loads, the power steering pump often needs repair.

First, let's look at the main reasons why a power steering pump may break:

• Improper installation, maintenance or repair of the system;
• Liquid leakage from the system;
• Airing the system;
• Accumulation of dust and dirt in the system;
• Pump overheating;
• Using the wrong fluid;
• Kinking of the oil lines of the system;
• Late replacement of fluid.

The difficulty of carrying out repairs lies only in the fact that the power steering pump for a Renault Logan car cannot be disassembled, which means that it does not have any covers or locking rings, but it is still possible to repair the pump. First you need to remove and disassemble the power steering pump according to the instructions that come with the kit. After this, you need to thoroughly clean it from dirt and dust, and also inspect it to determine the cause of the breakdown. The cause of the breakdown may be wear of the oil seal, in which case it needs to be replaced. When installing the oil seal, it may be necessary to modify the shaft.

Alternatively, you can secure the bearing in the middle of the power steering pump using the folded edges of the housing. After completing the repair, you need to reassemble the power steering pump in the reverse order.

Please note that after repairs, new parts may create some noise, but this is just the process of grinding in new parts. After repairs, be sure to replace the power steering fluid

Replacing the Logan steering rack: reasons for failure

The Renault Logan power steering steering rack is a fairly strong steering mechanism unit. The manufacturer determines its service life at 200 thousand km of vehicle mileage. Unfortunately, it is not always maintained. Most often this happens due to the driver's fault. The main reasons for node failure are:

• not timely maintenance;
• inaccurate driving on uneven roads;
• use of power steering fluid of an unauthorized brand;
• severe contamination of the chassis.

Additionally, this list can include natural wear and tear and manufacturing defects. But these reasons are quite rare in comparison with those listed.

Note to car enthusiasts

Regular maintenance of Reno Logan is the key to saving money, because everyone knows how much it costs to repair a breakdown, so the manufacturer pays special attention to describing the regulations and frequency of repair work in the operating manual.

We should not forget that, despite observing the required frequency for diagnosing steering control elements, most parts, including a conventional steering rack, and even a steering rack with power steering, will require replacement due to natural wear and aging (porosity on rubber anthers, etc.).

The next factor that can send a Renault Logan owner to service ahead of schedule is an aggressive driving style. The victims here may be:

• steering shaft;
• steering column switches;
• rack and pinion mechanism, etc.

The steering in Renault Logan is designed in such a way that it allows the owner to move comfortably without any sudden influence on the steering wheel.

Equipment without power steering

Let's see what the steering rack mechanism looks like in real life. The nut is located under the arrow (see photo).

Here is the stop nut

The nut itself can be turned with a 10mm hexagon. It's simple: rotation to the right corresponds to a decrease in the gap.

Preparation

The car will have to be driven into a pit - there are no other options. Lock the rear wheels with the handbrake.

Two nuts on each side

First you need to remove the crankcase protection. Take a 10mm socket wrench and unscrew 6 screws (2 on each of the three sides). It will be difficult to do without an assistant.

About the complexity of maintenance

A modern car cannot be imagined without power steering. The Reno Logan model is also equipped with this necessary mechanism for any owner. The power steering system is a complex unit and is prone to sensitivity to various operating conditions. This involves frequent preventive maintenance intervals.

To carry out repairs, craftsmen dismantle the steering rack with power steering, after draining the fluid from the system.

This procedure looks like this:

1. we use a special syringe that allows us to pump out fluid from the power steering reservoir;
2. remove the hose connecting the tank to the pump;
3. temporarily seal the opening of the tank;
4. lower the hose and direct it into a container for draining;
5. we help the draining process by rotating the steering wheel in both directions until it stops;
6. We wait for the fluid to completely drain.

If the diagnosis reveals the need to replace steering rods or ends, then the technicians must notify the owner about this, having agreed with him on the aspects of the repair. When purchasing the necessary spare parts that have failed, you will need to find out their article number.

When a consensus is reached, the procedure for changing the steering rack with power steering looks like this:

• lift the car (with a jack or lift);
• dismantle the crankcase protection;
• unscrew the three nuts holding the thermal protection of the rack and pinion mechanism;
• unscrew the 4 nuts securing the rail itself;
• remove the steering column switch mechanism;
• dismantle the lower flange of the elastic coupling;
• we separate the steering tips from the steering knuckles (if they don’t “come out” on their own, use a puller);
• working from the passenger compartment, remove the steering shaft;
• We remove the assembly from the car and begin the repair.
