Periodically check the condition of the springs, suspension springs and shock absorbers, their fastening and eliminate the identified malfunctions

Spring sheets must not be cracked.

Shearing the center bolt of the spring can cause longitudinal displacement of the sheets, and loosening of the stepladders can cause transverse displacement of the sheets.

To prevent corrosion and eliminate creaking, lubricate the leaf springs according to the instructions in the lubrication table.

Knocks and squeaks in the ears of the springs and spring suspension joints indicate wear or incomplete tightening of rubber bushings or wear of rubber-metal joints.

In this case, replace the hinges and bushings or tighten the bushings more tightly.

In order to increase the preload in the spring bushings, install rubber spacers (rings) cut from a chamber or similar rubber between them.

A sign of shock absorber failure is prolonged rocking of the car after driving over a bump in the road.

When servicing shock absorbers, periodically inspect and tighten their fastening in a timely manner, as well as check the condition of the rubber bushings in the ears.

The shock absorber does not require special adjustments during operation.

Disassemble shock absorbers only in the following cases:

- the occurrence of an unrecoverable fluid leak;

– loss of shock absorber force during tension or compression;

- fluid replacement.

Fig. 1. Shock absorber

The shock absorber should not be disassembled unless absolutely necessary.

Before disassembling the shock absorber, clean it of dirt, rinse and wipe it thoroughly.

Perform disassembly and reassembly in conditions that ensure complete cleanliness.

After the first 3000 km of run or when fluid leaks through the stuffing box 15 (see Fig. 1) of the stem and sealing rings 14,16, tighten the nut 18. The tightening torque is 78–98 Nm (8–10 kgf m).

If the leakage does not stop, remove the shock absorber, disassemble, inspect the o-rings and the hole of the guide sleeve 13 of the rod.

Replace stem seal, stem guide, reservoir O-rings, and other worn parts.

Install the rubber seal 15 with the inscription “bottom” on it to the piston.

When installing the oil seal, lubricate its internal surfaces mating with the rod with shock absorber fluid to reduce wear and prevent squeaking.

Reduced shock absorber performance or failure can be caused by clogged valve systems, settling of valve springs, or broken parts.

In such cases, disassemble the shock absorber, wash and replace sagging or broken springs and parts.
