11.3. Back suspension bracket

Back damping rack
Removal and installation

Fig. 11.11. Elements of fastening of a damping rack of a back suspension bracket: 1 – bolt and nut; 2 – clip of fastening of a brake hose; 3 – nut; 4 – top support of a rack


For access to fastening of a back rack remove a side upholstery in the luggage compartment. On models with three-stage system of damping disconnect the regulating switch. Turn off two nuts of the top fastening of a rack to a body (fig. 11.11).
If it is necessary to sort a rack, weaken a nut of fastening of a rod, record a shock-absorber rod from a provorachivaniye (it is impossible on models with three-stage system of damping). Do not turn off a nut completely.
Put tags for the subsequent combination of the top part of a rack with a body.
Lift a back part of the car and reliably fix on supports.
Remove a clip and disconnect a brake hose from a rack.
Turn off two nuts and take out two bolts of the lower fastening of a rack to a support of a nave of a back wheel, lower a rack down and remove from the car.
Check a rack for existence of leak of working liquid, damages of dustproof covers and a spring of a suspension bracket.
Installation is carried out to the sequences, the return to removal. Combine earlier put tags when fastening the top part of a rack to a car body.
Repair of a damping rack


Fig. 11.12. Elements of a damping rack of a forward suspension bracket: 1 – nut and washer of fastening of a rod; 2 – top support of a rack; 3 – laying of a spring; 4 – dustproof cover; 5 – spring; 6 – compression course buffer; 7 – shock-absorber


Repairs of a damping rack of a back suspension bracket are made as well as a damping rack of a forward suspension bracket (fig. 11.12).

Three-stage control switches of damping of a back suspension bracket
Check
Open a trunk lid and remove an internal upholstery for access to switches of a back suspension bracket.
A further inspection of three-stage control switches of damping of a rack of a back suspension bracket is carried out as well as racks of a forward suspension bracket.
Removal and installation
Remove a rack of a back suspension bracket (it is recommended by the manufacturer, but it is actually optional).
Disconnect the contact socket from the switch.
Turn out screws and remove the switch from the top part of a rack.
Installation is carried out to the sequences, the return to removal.

Cross and longitudinal drafts of a back suspension bracket
Removal
Lift a back part of the car and reliably fix on supports.
Remove the fuel tank.
Note the provision of a gear adjusting wheel and nut for their subsequent installation in initial situation. Movement of a nut and cogwheel influences a positive convergence of back wheels.

Fig. 11.13. Cross and longitudinal drafts of a back suspension bracket: 1 – nave of a back wheel; 2 – nuts; 3 – plug and clamp; 4 – cross draft; 5 – coupling bolt, nut and laying; 6 – clamps, plug and laying; 7 – clamp, plug and bolt; 8 – bolt and nut; 9, 11– bolts; 10 – longitudinal draft; 12 – nut


Turn out bolts and nuts of fastening of cross thirsts for a cross-piece (fig. 11.13). Turn out nuts and bolts, remove plugs and disconnect drafts of the stabilizer of cross stability (if it is installed).
Turn out bolts of fastening of longitudinal side drafts from a support of a nave of a back wheel, then remove drafts from the car.
Turn out a bolt of fastening of a suspension bracket of the parking brake.
Turn out coupling bolts and remove longitudinal side drafts from the car.
Installation
Installation is carried out to the sequences, the return to removal, taking into account the following. Temporarily screw all bolts and finally tighten them after lowering of the car on wheels.
Check a positive convergence of back wheels.

Replacement of the hug bearing
Remove a nave, bearings and an epiploon.
The blunted chisel or core beat out rings of bearings from a nave.
Clear nests for rings of bearings in a nave. Grease new rings and press them into place. Make sure that rings are established without distortion, otherwise they can be damaged.
Grease and install bearings and an epiploon, then establish and adjust a nave.

Nave support
Remove knot of a brake drum / nave.
Disconnect a brake tube from the working brake cylinder. Be ready to an effluence of brake fluid.
Turn out four bolts fixing the protection cover of a back brake on a nave support. Remove a plate of a drum brake and take it aside in admissible limits of the course of a cable of the parking brake.
Turn out bolts of fastening cross and longitudinal thirsts and a back damping rack for a nave support. Remove a nave support from the car.
Installation is carried out to the sequences, the return to removal.
Remove air from the hydraulic drive of the brake system, adjust hug bearings and the parking brake.
