Removal
Remove the wheel.
Remove the coil spring.
Fig. 4.60. Fastening the parking brake wire
Remove fastening 1 by pressing out the inner rivet rods (Fig. 4.60).
Unscrew connecting rod 2 from the longitudinal arm.
Remove the bolts.
Release the electrical wire from the clamp on the support bracket.
Mark the mounting position of the support bracket on the body.
Remove the bolts.
Fig. 4.61. Fastening the support bracket
Remove longitudinal arm 1 with support bracket (Fig. 4.61).
If necessary, replace the trailing arm, it is necessary to remove the support bracket from the arm.
Fig. 4.74. Installing the longitudinal lever in a vice
Clamp the longitudinal lever in a vice so that the support bracket 1 touches the vice (Fig. 4.74).
Unscrew bolt 2.
In this case, it is necessary to adjust the mounting position of the support bracket relative to the longitudinal arm.
Determining the mounting position of the support bracket relative to the longitudinal arm
Fig. 4.75. Scheme of installation of the support bracket relative to the longitudinal arm: 1 – support bracket; 2 – longitudinal lever
Measure dimension a from the center of the bolt to the outer edge of the support bracket.
Size a is 57.5±1 mm.
After setting dimension a, tighten the bolt.
Installation
Fig. 4.76. Tightening position of the bolts securing the trailing arm to the hub bearing housing
The threaded connection of the trailing arm to the wheel bearing housing can be tightened only if the other parts (spring and shock absorber - mandatory) of the suspension of the corresponding wheel have already been installed. When tightening, the wheel suspension must be unsprung. Only now the trailing arm and wheel bearing housing are moved to the desired position (Fig. 4.76).
When performing the following operations, it is necessary to strictly follow the sequence of actions.
Install the trailing arm and support bracket with bolts onto the wheel bearing housing, loosely.
Fig. 4.77. Installing the connecting rod
Insert connecting rod 1 into the longitudinal arm without tightening the nut (Fig. 4.77).
Raise the wheel suspension using an engine/transmission jack and jack stands until the support bracket contacts the body.
Tighten the bolts to the old mark.
Lower the wheel suspension back onto the strut and remove the support from the hub.
Install the coil spring.
Tighten the trailing arm bolts to the specified torque, making sure that the parts are in the correct position.
Tighten the tie rod nut onto the wheel bearing housing.
Remove the fastener by pressing out the inner rivet rods.
Install and tighten the wheel.
Adjust the wheel alignment angles.
