Tie Rod End Replacement
For removal, a puller is required, because. after unscrewing the bolt, the tip is not so easy to remove from the steering knuckle lever due to its tight fit, and it will not be possible to do without tools.
Remove wheel.
Loosen the self-locking nut under the tie rod end.
Press the tip out of the steering knuckle arm with a puller (6) on the shock absorber housing.
Loosen locknut (4) on the rudder (1), while holding the hexagon on the threaded part (3) with two spanners (2).
Mark the position of the twisted tie rod end (5), so as not to disturb the wheel alignment during assembly.
Unscrew the tie rod end and screw in a new one to the mark.
Insert the ball head pin of the tie rod end into the steering knuckle arm and, if necessary, carefully hammer it in.
Tighten new self-locking nut to 60 Nm.
Tighten locknut to 40 Nm.
Check wheel alignment.
Tie rod replacement
Separate the tie rod end from the steering knuckle arm.
In the engine compartment, unscrew the steering rod from the steering gear.
When tightening (60 Nm) new tie rod on the steering leash, the car must be on wheels on the floor. Otherwise, the rubber-metal support of the inner tie rod mount will be compressed, which will lead to its premature wear.
Steering gear adjustment
Steering play can be eliminated by adjusting both mechanical and power steering. It is assumed that the wear of the gear rack is still small.
Set wheels to straight ahead.
Carefully turn the self-locking adjusting bolt to the right by approx. 20°using the transport.
During a test drive, check whether the steering returns to the straight-ahead position on its own after cornering.
If this is not the case, then turn the adjusting bolt a little further.
If there is still play in the steering after this, then you can turn the bolt further to the right.
In general, the steering after this adjustment should turn from lock to lock without jamming and clamping.
If it is clamped with the wheels turned, during the test in the straight-line position there is play, then the steering mechanism must be replaced.
Checking the power steering for tightness
If there is a decrease in the fluid level in the reservoir, then it is necessary to check the entire steering system, otherwise it may unexpectedly fail in motion. The check is carried out as follows:
Turn the steering wheel once to the right and to the left as far as it will go. This creates the most pressure in the power steering and leaks can be detected.
While holding the steering wheel in the end position, check the following areas for leaks:
- Rotary piston valves (rotor). It's located around there. where the steering column enters the steering gear Oil can leak into the interior of the vehicle ahead under the instrument panel at the bulkhead.
- At the gear rack seal or at the stuffing box in the left handpiece. To check, loosen the collar of the corrugated casing and move the casing to the middle.
- At the pump of the central hydraulic device. To determine leaks, you must first wash the engine.
- At pipeline connections. Check all connections individually and tighten if necessary.
Other leak locations may be at the brake booster, ride height control system, or pressure damper.
Checking the cuffs of the steering mechanism
Behind the bottom in the engine compartment is a steering mechanism, the gear rack of which is protected by rubber cuffs (arrow). They must be checked regularly. A cracked bellows will allow water and dust to enter the steering gear, and this mixture with grease forms a kind of grinding paste that will quickly ruin the rack and pinion guide and steering gear.
Stretch the bellows with your hands to check for cracks in the rubber tabs. Check if both clamps are firmly seated on the outer ends of the rubber cuffs?
Replace defective cuff immediately.
Attention. To replace defective steering gear seals, it is necessary to remove the steering gear with the rack completely, which, especially for power steering, is beyond the capabilities of cars. Despite this, this work must not be delayed in order to avoid more serious damage.
Checked dust caps and tie rod ends
The tie rod ends at the outer ends of the tie rods consist of steel ball heads which are contained in a plastic bushing with little lubrication and require no maintenance. The hinges are protected from dust and moisture by rubber caps, the condition of which must be checked frequently
Check the dust seals for cracks around their entire circumference.
Tie rod ends with cracked collars should generally be assumed to be defective and replaced.
If the hinges detect play, then it can be installed independently on a raised vehicle. shaking the wheel around its vertical axis or pulling the tie rod.
Another possibility, when the assistant turns the steering wheel back and forth, with the car on the ground, put his hand on the hinge to check the clearance.
Tie rod ends with play must be replaced immediately!
Similarly, it is checked whether there is play in the rubber-metal joint of the steering rod in connection with the steering mechanism.
If one of the bearings is damaged, then the entire tie rod will have to be replaced.
Checking the dust caps of the axle joints
The suspension joints on the front axle between the cross member and the suspension struts are maintenance free. The steel ball heads of the axle joints are lubricated and additionally in plastic liners.
Plastic dust caps serve as protection against moisture and dirt. Dirt in the hinge acts like sandpaper, and moisture leads to rust.
Turn the steering wheel fully to one side.
Check the axle hinge caps on the right and tear for damage.
A damaged dust cap can be replaced separately when it is ensured that no more dirt enters the hinge.
If necessary, it is necessary to replace the entire transverse lever, because. hinge does not separate.
Checked the play of the hinges of the bridge
Control is necessary, in our opinion, only on cars with a mileage of more than 800 km.
Support the vehicle so that the corresponding wheel hangs freely.
Grasp the wheel from above and below and shake it, perpendicular to the direction of travel.
If play is found, then you should contact the workshop for a more thorough check and repair.
Steering play check
Lower the left side window. Stand next to the car.
Through the open glass, grab the steering wheel and move it back and forth.
Does the left front wheel move from straight ahead immediately with the steering wheel? Pay attention to the wings, because. elastic tires can "absorb" part of the turn before the wheel starts to move.
On vehicles with power steering, the play is checked with the engine running.
