Suspension bracket of back wheels and the back bridge
There are two variants of a design of a back suspension bracket for Frontera. The car to the middle of 1995 of release has a rigid axis on flat springs and hydraulic shock-absorbers. On later models the back suspension bracket with four cross-section levers and screw springs and газонаполненными shock-absorbers has been entered.
The description of old model of a suspension bracket here is not resulted. The description of the new suspension bracket having more difficult design is more low given.
Longitudinal levers of a suspension bracket are executed from pipes. Short, located in the centre over картером differential the lever, serves for perception of the loadings arising in the course of braking and dispersal. Lateral fastening is carried out by means of draught of the cross-section lever, the so-called cross-section jet bar fixed by one end behind on the right to the bridge, and other end at the left to the chassis.
The suspension bracket has the stabilizer of cross-section stability established on rubber plugs in front of the bridge and connected with the bridge by connecting bars with spherical hinges.
Levers and cross-section jet bar have the rubber plugs possessing the minimum friction that provides free moving of a suspension bracket at car arrival on various roughnesses of road. The bridge and a suspension bracket are shown on an illustration.
The back bridge with screw springs of a suspension bracket
Two are applied to a drive of the back bridge various карданных a shaft. At three-door cars карданный a shaft whole. At cars with the increased base (5 doors) it is applied карданный a shaft, two-piece, having an intermediate support.
Besides, there is a difference in a design of the back brake mechanism. Drum-type and disk brakes that influences performance of some works are applied.
At performance of repair work it is necessary to take into consideration distinction in a design of a back suspension bracket. If in the text there are no corresponding instructions, works for both executions of a suspension bracket are carried out equally.
At performance of works on a back suspension bracket it is necessary to be guided by the instructions resulted in the beginning of section "Suspension bracket of forward wheels". It is not necessary to forget about necessity of reliable fastening of the car.
REMOVAL AND BRIDGE CARTER'S INSTALLATION
In the description resulted more low it is necessary to distinguish cars with a suspension bracket on flat springs and a suspension bracket with screw springs. It is preliminary necessary to find out, what type of the car at you.
Back part of the car lift and establish on supports. Turn away bolts of fastening and remove both wheels.

Installation
At bridge installation keep in mind the following:
Check up a condition of step-ladders. Step-ladders after their removal "disperse". Therefore it is necessary to check up, whether step-ladder cores enter into apertures on the bridge. If is not present, one core of a step-ladder is clamped in a vice, and the second is cautiously turned in.
Can happen that at installation of the new bridge it is necessary to transfer a brake hose and the pipeline, and also cables of a drive of a lay brake from the old bridge.

|
|
4. From below establish and fix bolts of a lining of step-ladders. The basic pin of the shock-absorber on a step-ladder should be turned inside, as shown. |
| 5. Screw four nuts and in regular intervals cross-wise press out them. |
| |
6. Fix the shock-absorber from below. The arrangement of details of fastening is shown on an illustration. |
| 7. Do not forget to establish a spring washer. |
| 8. Nuts tighten the moment of 40 Nanometers. |
| 9. Establish the buffer. |
| 10. Fastening bolts tighten the moment of 42 Nanometers. |
| 11. Fix a hose of ventilation of the bridge. |
| 12. Connect flanges карданного a shaft and a leading gear wheel of the main transfer according to marks and insert new bolts. Old bolts are not established. |

| 16. Yet шплинтуйте. |
| 17. Fix a brake hose on a square and put a spring clip. Watch correct position of a hose. |
| 18. Screw and tighten накидную a nut of the brake pipeline. |
|
|
19. Fix cables of a drive of a lay brake according to an illustration lock plates on the chassis. |
| 20. Lower the car on wheels and in regular intervals cross-wise tighten nuts of fastening of step-ladders of springs the moment of 68 Nanometers. |
| 21. Tighten корончатую a nut of draughts of a regulator of pressure of a brake the moment of 13 Nanometers and зашплинтуйте. |
| 22. In summary remove air from brake system as it is described in Chapter 9. |
| 23. Turn out a stopper from the bridge and check up oil level. If necessary add oil. If oil merged from the bridge, it is necessary to fill in it again. |

Installation
Bridge installation is carried out in sequence, return to removal. Thus it is necessary to mean the following:
Can happen that at installation of the new bridge it is necessary to transfer brake hoses and pipelines, and also cables of a drive of a lay brake from the old bridge.
The assembly elements having a rubber covering, should not be exposed to influence of lubricants. It is impossible to hold also lubricants near to the specified places.
| PERFORMANCE ORDER |
| 1. Bolts and nuts of fastening of all assembly elements having a rubber covering, at first tighten by hand. |
| 2. After car lowering on wheels the specified connections tighten the established moments. |
