11. Remove the reinforcement at the subframe rear mounting point.



12. Remove the two steering gear retaining bolts.

13. Remove the front exhaust pipe section.

14. Detach the gearbox torque arm from the subframe.


15. Detach the suspension arms from the subframe.


16. Detach the anti-roll bar from the subframe.

17. Unscrew the air cleaner retaining nuts from the subframe.


18. Remove the A/C pipes from their brackets.


19. Detach the power steering pipe from the clips.

20. Run trolley lift 83 95 311 with parent fixture 83 94 801 , intermediate support 83 95 170 , basic fixture 83 95 188 and jig 83 95 196 underneath the car and remove the remaining subframe bolts.

21. Lower the subframe.


22. Unbolt the brackets for the A/C pipes.


To fit



1. Bolt the brackets for the A/C pipes in place.

2. Mount the brackets for the radiator assembly.

3. Lift up the subframe carefully. Make sure the rubber boots on the inner drivers do not knock against the middle brackets on the subframe before the subframe is firmly against the body.

4. Fasten the power steering pipe in the clips.

5. Guide the radiator guide pins into the subframe. Lubricate with petroleum jelly to make fitting easier.

6. Guide the A/C pipes into their holders on the subframe.

7. Fit the power steering cooling pipe.

8. Adjust the subframe so that the bolt holes are aligned with the body. There are two guide pins front left and rear right on the lifting trolley that will guide the subframe to its correct position.

9. Fit the bolts to secure the subframe and the rear support plates. Tighten the bolts enough to ensure the subframe does not move when the lifting trolley and fixture are removed.

Note

The middle bolts on the subframe must not get mixed up with the others. The middle bolts have a smaller washer and 20 mm head.
