7.2.3. Removal and installation of a beam of a back suspension bracket

Fig. 5.12. Back suspension bracket: And — with a drum-type brake; B — with a disk brake; 1 — a cross-section beam; 2 — a nut of a rod of the shock-absorber; 3 — the plug; 4 — a lining of the top support; 5 — the top support of the shock-absorber; 6 — the top basic cup of a spring; 7 — the buffer of a course of compression; 8 — a protective cover; 9 — a suspension bracket spring; 10 — the shock-absorber; 11 — a brake board; 12 — a nave; 13 — a washer; 14 — a nut of fastening of a nave; 15 — шплинт; 16 — jet draft; 17 — the cross-section lever

At work be guided fig. 5.12 and 5.17.

Fig. 5.17. Sizes of the cross-section lever of a back suspension bracket and jet draft: And — the cross-section lever; B — jet draft; and = 207 — 208 mm; = 394 — 395 mm; in = 601 — 603 mm; g = 106 — 108 mm

The big opening of jet draft serves for fastening to a suspension bracket beam; a small opening — for fastening to the cross-section lever of a suspension bracket.

Lift a back part of the car and establish on supports. Remove the back

wheels. Pump out a syringe liquid from a tank of brake system. Disconnect brake hoses and wheel sensors (in the presence of ABS).

Fig. 5.18. Fastening of the cross-section lever of a back suspension bracket: 1 — a bolt of fastening of the cross-section lever to a body; 2 — a bolt of fastening of the cross-section lever to a beam of a back suspension bracket; 3 — bolts of fastening of jet draft

Disconnect a cable of the parking brake from brake mechanisms from both parties. Release a cable from clamps on a suspension bracket beam. Prop up a beam of a back suspension bracket, using a jack or supports. Turn out a bolt 1 (fig. 5.18) of fastening of the cross-section lever to a body. Turn out bolts of fastening of telescopic racks to a back beam (see fig. 5.14). Turn out bolts of fastening of longitudinal levers of a beam to a body and carefully lower a beam of a back suspension bracket.

Installation carry out in sequence, with return to removal, thus replace everything самоконтрящиеся nuts. Tighten carving connections by the set moments specified in appropriate section. Pump over brake system and adjust the parking brake. Check corners of installation of back wheels.
