REMOVAL - REFITTING TORSION BAR (REAR)

1 - SPECIAL TOOLS

[1] slide hammer (-).0316-A .

[2] dummy damper (-).0539-D .

[3] adaptor (-).0539-C .

2 - REMOVAL

Vehicle on its wheels : REMOVE THE DAMPER .

Remove : The wheels .

Fit the dummy damper [2] .

Adjust its length (1/2 turn = 0,5 mm) to allow free engagement of both eyes .

Tighten the lock nut and the dummy damper fixings .

Remove :

- the bolts (5)
- the thrust washers (6)

Remove :

- the bolts (7)
- the thrust washers (8)

IMPERATIVE : mark the position of the bar in the arm with two centre punch marks (a) and (b) .

Fit :

- the adaptor [3] to the end of the anti-roll bar
- slide hammer puller [1] on the adaptor

Stage 1 :

- push the torsion bar to release it

Stage 2 :

- pull the torsion bar to remove it

Restrain the arm to prevent it from coming out with the the bar .

Remove the slide hammer and adaptor .

WARNING : before removing the dummy damper, support the arm to maintain its approximate position .

Remove the dummy damper [2] .

Measure the dimension (X) of the dummy damper [2] .

3 - REFITTING

Adjust the dimension (X) of the dummy damper [2] :

- to the value determined for ride height correction
- to the value shown in data if the torsion bar is being replaced
- to the value measured on removal in other cases

WARNING : do not reverse the bars when refitting .

Right hand bar : paint ring (A) .

Left hand bar : two paint rings (B) .

Clean :

- the torsion bar splines
- the internal splines in the arms

Coat the splines of the bar with ESSO NORVA 275 grease .

Insert the bar through the arm bracket :

- in the case of ride height correction, offset the marks made on removal by the number of splines determined
- in the case of a new torsion bar, find by rotation, spline by spline, the position where it enters freely 8 to 10 mm
- in other cases, align the marks made on removal

NOTE : the spline end of the bar cannot be fully inserted as its ends are not in the same axis .

Due to the even number of splines at the ends of the bar, it can be freely inserted in two diametrically opposed positions without modifying the ride height .

Complete insertion of the bar up to its stop using the slide hammer [1], [3] .

Remove the slide hammer and adaptor .

Fill the recess with ESSO NORVA 275 grease .

APPLY A BEAD OF GREASE TO THE ENDS OF THE BAR SPLINES .

APPLY A BEAD OF GREASE TO THE ENDS OF THE BAR SPLINES .

Position (Depending on the operation) :

- the thrust washers (6)
- the bolts (5)

Tighten the bolts (5) to 2 daN.m .

Position (Depending on the operation) :
