Attention! The suspension springs must be replaced in pairs for each axle!
1. If equipped, disconnect the brake pressure regulator rod from the rear axle housing (see accompanying illustration - models without EBV).
2. Disconnect the diagonal suspension rod from the frame.
3. Disconnect the vent line.
4. Support the front wheels with wheel chocks, jack up the rear axle, then place supports under the trailing arm brackets.
5. Loosen the nuts and remove the bolts of the lower shock absorber mounts (see Section Removal, checking and installation rear shock absorbers).
6. Lower the axle and remove the suspension coil springs - try not to pinch the brake lines when lowering the axle.
7. If necessary, remove the rubber buffers.

8. Installation is carried out in the reverse order - make sure that the ends of the spring rods rest against the special projections of the lower plates.
Note: Replacement springs must be color coded the same as the originals.
