4. Unscrew necked down screws of wheel carrier (80) support left and right.
5. Unscrew hex bolts of holding bracket of torsion bar bearing right and left.
6 .Remove torsion bar toward the right.

Installation





7. Check rubber mount of torsion bar bearing and rubber mount of wheel carrier support on torsion bar.
8. Check threads for necked-down bolts in wheel carrier for easy operation and refinish, if required.
9. If required. mount lever for operating level controller to torsion bar.
10. Introduce torsion bar, slip rubber mount with separating slot on top on torsion bar.
11. Attach torsion bar to frame floor, while making sure of correct position of upper and lower holding bracket.
12. Mount exhaust line and righthand rear wheel.





13. Lower vehicle rear end - if required by loading trunk until flat surface of inner bushing of rubber mount (80g) in torsion bar link is in alignment with surface of wheel carrier (91a).

Note: On vehicles without flat surface on wheel carrier (starting approx. January 1975) tighten necked-down bolt of wheel carrier support on torsion bar only when the vehicle is on its wheels ready for driving.

14. Connect torsion bar support with wheel carrier.

Attention! The bearing surfaces must be absolutely clean and free of grease. When tightening, make sure of correct seat of inner bushing of rubber mounting on wheel carrier.
