Steering rack "Renault Megane-2": features, device. Replacement steering rack "Renault Megane-2"

The Steering is a combination of the mechanisms through which the vehicle moves in a predetermined direction by the driver. The pressure from the steering mechanism is a steering transmission which provides a turn of the front wheels in the required direction.

A disruption in the operation of at least one of these nodes may lead to accidents on the road.

What is a steering rack

The Car "Renault Megan-2" have the steering rack-and-pinion mechanism and steering column, tilt angle which can be adjusted. The car was produced with both the hydro-and electric power steering.

The steering Wheel is installed on the splines of the steering shaft self-locking nut and equipped with the airbag module.

Steering shaft consists of upper, middle and lower divisions. Mid - folding, with two u-joints at the ends.

Steering rack "Renault Megane-2" transferring momentum to the wheels and provides control of the car. In good condition it doesn't make any sound, and the force from the steering wheel transmits without delay.

In the case where this node appears a knock, especially on uneven and impact into the steering wheel, which does not take its original position after the turn, the car goes for repairs, as the rail is the problem.

Components steering rack

Steering rack "Renault Megane-2" consists of:

• The rack (the shaft with the teeth), which are mounted on rods and tips;
• Shaft connected to the cardan shaft of power steering;
• Needle and ball bearings;
• Adjusting a cracker;
• Nuts for mounting the breadcrumbs;
• Sleeve.

For reviews of the owners of the "Renault Megane-2", self-repair steering rack - it's quite a laborious process: only one withdrawal can take an hour of time. And the cranky part - bushing - often broken during removal and creates additional problems.

Common problems

The Most common symptoms of failure of the steering rack are:

1. A Puddle of oil, especially after long Parking. This is a sign of damage to the seals. This happens when the steering rack boot is damaged or incorrectly installed. As a result, the stock get dirt and water. In this case it will be enough to replace the seals, bushings and o-rings.
2. Backlash. most Often, the occurrence of backlash caused by a problem with the steering cross, however, there may be other reasons. Therefore, it is recommended first to diagnose the whole site, to troubleshoot, replace the used part to be adjusted on a special stand.
3. A Knock in the steering rack. It appears when worn sliding bushing, a clamping mechanism or the boot. This will need some diagnosis and testing on the bench with the subsequent replacement of parts.

How to pull up the rail

Before starting a laborious process of repair and replacement, worth a try to tighten the steering rack "Renault Megane-2". This work will require skill and multiple extension cords for the key on the 12". For greater convenience in the work it should skip over the subframe. Tighten the adjusting bolt should not be, because the steering wheel will have to rotate the extra effort.

1. Put the car up on the lift.
2. Remove the protection.
3. Touch determined by finding the adjusting bolt.
4. The Key to slowly turn the bolt.
5. Periodically rotate the wheel in different directions, thereby check the presence of extraneous sounds in the work of Reiki.
6. End to tighten the bolt when the sounds disappear when steering.

In a situation when adjustment bolts are not eliminates knocks, there is a need for repair or full replacement. In the absence of kit on one HUNDRED and offered to completely replace the node, respectively, the price of the steering rack "Renault Megane 2" will be several times more than the self-replacement of worn elements.

Withdrawal

To reach this node, it is necessary to remove the right wheel and the subframe, remove the nut on the steering tip to remove it. Remove the steering wheel to the left until it stops and remove boot clamps of the rail. Unscrew contrawise tip and the ferrule. To remove the boot. Unscrew thrust.

The Rake taken from the car and clamped in a vise.

Plan showdown

Disassemble the steering rack need to gradually. In order to better visualize the sequence in which it is necessary to dismantle the elements, below is a schematic drawing of the steering rack "Renault Megane-2".

1. Tighten the Screw directly into the bushing on the steering shaft is not more than 1 cm and with a pair of pliers pull out the oil seal. Then pull out oil seal screw.
2. Remove the Snap ring using the special puller.
3. Fix a steering shaft in a vise and gently tapping the body of the rack, remove it along with the bearing.
4. Extract the bushing, prying it with a screwdriver and also gently tapping the rail.
5. Unscrew the nut of the biscuit and remove it.
6. All the removed parts should be thoroughly rinsed.

There is in the steering rack is anotherthe bearing, which is with difficulty removed. Some craftsmen beat it with a ground down bolt for 10" and 13". But there are those that separately take out the needles and pieces of the body, and the outer holder out, drilled the rail on the back side. In any case, it will have to change.

The Dismantled rail degreased, treated with cold welding and leave for 6 hours to dry completely. In place of the bearing seat lay a rag or paper that didn't weld.

After a thorough drying rack re-wipe.

The Bearing on the steering shaft has a snap ring. It is disposable: after removing the back to install it anymore. So you can cut it with a jigsaw and remove Ushguli. The bearing is also permanently removed (using a hammer).

Build

A New bearing pressed on the steering shaft, worn snap ring. While this design can be put aside. The Assembly of the slats is performed in several stages:

1. Carefully install the Bushing on the rail on the right and fill with grease.
2. Shaft inserted in the sleeve. There will have to make the effort.
3. Then the shaft ottsentrovano and treated with lubricant.
4. To free the end put the needle bearing.
5. Unfold the shaft to the correct position on the rack, and gently score it in the case.
6. The Left side of the pull shaft with the nut.
7. Twisting the rail to the right and left alternately, grease the shaft, like a biscuit.
8. Install the nut, spring and biscuit.
9. Put the retaining ring and seal.

Adjusting Reiki

The Process of adjustment of the repaired Reiki is also suitable for diagnostics:

1. Tighten the biscuit until it stops, and then turns it 180^O.
2. Rail turn right and pull the shaft in side of her.
3. Turn the rack to the left and repeat the procedure with the shaft.
4. Centering the Rail. And again pull the shaft in different directions.

In each of these points, the main shaft needs to maintain its position on the rack, but to spin. Repair steering rack "Renault Megane 2" is completed. Now fasten the thrust and installed it on the car. The whole process takes about 3 hours.

After replacing the steering rack "Renault Megane-2" we need to conduct alignment. Otherwise all the work done will be in vain.

How to reduce repair costs

Following the simple rules, you can prevent serious damage to the steering column and to reduce the cost of buying parts.

1. If the vehicle is equipped with hydraulic steering, there is at least once a month to check the colour of the hydraulic fluid (it should be transparent) and to make timely replacement. The black color of the liquid indicates that soon goes down the pump, and with it the whole steering rack. Unfortunately, the power steering system has no filter. Accordingly, the liquid can get different particles that pollute it, and in the case of Reiki act as abrasive.
2. To Periodically inspect the anthers, especially after repair the front suspension. They should not be twisted, have cracks and gaps. If there is a defect, albeit small, is the anther to replace.
3. In case of a rumbling sound or knock when turning the steering wheel should immediately engage in the diagnosis and subsequent repair of the steering rack "Renault Megane-2".
4. Due to long-term operation there is a risk airing the system, hydrosaline helm. You can remove the air from the system by scrolling the wheel 5 times from one side to the other until it stops. If that doesn't work, the experts STO pump system high pressure.
5. With the advent of sound from the rotation of the steering wheel while stationary you need to inspect the drive shafts, CV joints anthers, bearing, outer and inner hinges.
