Helpful advice. Repairing the telescopic pole usually does not lead to the desired result, so it is recommended to replace it if necessary.
1. Remove the telescopic pole from the vehicle (see «Removal and installation of a forward rack»).
2. Clamp the telescopic strut in a vise, compress the spring with special ties and unscrew the shock absorber rod nut using the tool, holding the shock absorber rod from turning.
3. Remove the top support of a rack.
4. Remove the top cup and then the spring.
5. Remove the protective cover with the compression stroke buffer from the telescopic strut.
If cracks, deformation, or damage are found on the strut body, lower spring cup, pivot arm, and bracket, replace the strut. It is forbidden to carry out welding work on the stand, this may affect its performance.
6. Set the telescopic stand vertically and lower and raise the shock absorber rod several times until it stops. When moving the stem, make sure that it moves without dips, jams and knocks. Otherwise, replace the stand. Also, replace the telescoping pole if there are signs of fluid leakage (slight fogging is allowed in the upper part of the rack housing) and if the threads in the upper part of the stem are damaged.
7. The telescopic pole can be repaired, but it requires a special tool and skill. Therefore, it is recommended to sort it out in a specialized workshop.
8. Shock absorbers can be installed on the car, in which all elements are assembled in a non-separable case (cartridge). To replace the cartridge, knock down the compression buffer support, unscrew the strut body nut with a special wrench, remove the old cartridge and install a new one. When replacing a conventional hydraulic shock absorber with a cartridge, remove the rod with the working cylinder from the body and drain the liquid. Flush the body cavity and install the cartridge in it in accordance with the manufacturer's instructions.
9. Replace damaged compression stroke buffer and cracked, torn, or buckled guard. Also replace the casing when the metal fittings peel off from the rubber.
10. Replace the bearing if it has axial movement in the support housing, there are traces of lubricant leakage from under the protective rings, the bearing seizes when turning and corrosion. If cracks are found in the upper support housing, replace the housing or support assembly. Replace also studs with damaged threads (see «Replacing the top support of the telescopic pole»).
11. Replace the spring if cracks are found on it or coils are deformed.
To check the settlement of the spring, squeeze it three times until the coils touch. Then apply a load of 3187 N to the spring (325 kgf). The length of the spring under the specified load must be at least 201 mm (182 mm - for cars supplied for export). Compress the spring along its axis, the supporting surfaces must correspond to the surfaces of the supporting cups on the telescopic pole.
If the length of the spring with yellow (white - for cars supplied for export) marking (class A) less than 207 mm (188 mm - for cars supplied for export), replace it with a spring marked green (blue - for cars supplied for export) (class B). It is recommended to replace both front suspension springs, the springs must be of the same group.
Replace damaged upper spring cup.
Replace the rack mounting bolts with damaged threads.
12. Reassemble the telescopic pole in the reverse order of disassembly. Slide the protective cover over the annular groove of the compression stroke buffer.
13. Install the spring so that its end rests against the protrusion of the lower cup.
14. Install the top cup onto the spring in the same way.
15. Establish a forward rack on the car in an order, the return to removal.
16.Finally tighten the damper rod nut with the vehicle on the ground and adjust steer angles.
