In the spare part racks which can be got in exchange for old with surcharge are delivered. Before dismantling of knot of a rack be convinced available necessary spare parts.
Prevention

2. Squeeze a rack spring adaptation to unload a rack.
3. Remove a protective cap of a nut of a rod of the shock-absorber. Release a nut, holding a rod.
4. Turn off a nut, remove the rack bearing, laying and a washer. Check freedom of rotation of the bearing. Replace the jamming bearing. Check a condition of rubber laying. In the presence of cracks, wear and peeling of rubber replace laying.
5. Remove a plate springs and a rubber ring. Replace the damaged ring.
6. Carefully remove the compressed spring and you store it in a steel case.
7. Pick up the protective phone and the rubber buffer from a rod. Check their state and if necessary replace.
8. Turn off a cap nut and remove the shock-absorber, merge from it oil.
9. Fill in in the shock-absorber 20–25 cubic see oils for the engine (except gas-filled shock-absorbers). Oil provides heat removal to the case of the shock-absorber and viscosity of the oil which is filled in in the shock-absorber does not matter.

10. Assembly is carried out upside-down. Tighten a cap nut and a nut of a rod with the set moments. Combine the termination of a spring with a fillet on rubber laying of a spring and on a cup.
