Inspection
1. For ease of access, fully apply the parking brake, raise the front of the vehicle and support it securely (see "Lifting and installing the car on supports").
2. Check the rubber of the supports for cracks, hardening or separation from the metal. If there are obvious defects, replace the support.
3. Check the tightness of the nuts/bolts securing the supports. If possible, use a torque wrench to check.
4. Check the bearings for wear. To do this, carefully pry up the support with a large screwdriver or other lever and check for play. When this check is not possible, have an assistant move the engine/gearbox back and forth or left and right while observing the mounts. Although some play is inherent even in new elements, you will clearly see increased wear. If excessive play is detected, first check that the bolts/nuts are tightened correctly and then replace the worn parts as described below.
Replacement
Right support
5. Place the jack under the engine, placing a wooden block on the jack head. Raise the jack enough to relieve the engine mounts.
6. Loosen the clamps and brackets and position the lift pump and all associated hoses, wires and cables away from the engine mount and upper suspension mount.
7. Unscrew the three nuts securing the upper bracket to the bracket on the engine.
8. Unscrew the single nut securing the support bracket to the rubber support and remove the bracket.
9. Using a strap wrench or similar tool, remove the rubber mount from the body. Alternatively, fabricate a tool from a suitable metal pipe, which should have projections that fit into the cutouts in the support.
10. Check all components for signs of wear or damage and replace if necessary.
11. When assembling, screw the rubber support into the body and tighten it securely.
12. Install the support bracket onto the rubber mount and bracket on the engine and tighten the corresponding nuts to the specified torque.
13. Replace the booster pump and hoses, wires and cables that have been moved for easier access.
14. Remove the jack from under the engine.
Left support
15. Remove the battery, battery tray and backing plate as described in chapter 5A.
16. Place a jack under the gearbox, placing a wooden block on the jack head. Raise the jack enough to relieve the load on the transmission mounts.
17. Unscrew the central nut of the rubber support on the left support and remove it together with the washer. Then unscrew the support mounting nuts and remove the support from the engine compartment.
18. If necessary, remove the spacer element (if available) from the support stud, then unscrew the stud from the top of the gearbox housing and remove it together with the washer. If the stud is tight, you can use a universal stud puller to remove it.
19. Carefully inspect all components for signs of wear or damage and replace if necessary.
20. Clean the threads of the support stud and apply thread locking compound to them. Screw in the stud (don't forget to put a washer underneath) into the top of the gearbox and tighten it securely.
21. Put on the spacer element (if available) onto the support pin, and then install the rubber support. Tighten the support mounting bolts to the body and the support center nut to the specified torque and remove the jack from under the gearbox.
22. Install the battery support plate, battery tray and battery as described in chapter 5A.
Rear support
23. Contact paragraph 16 of chapter 2A.
