1. Remove pendulum support 10Assembly mountings; Removing and installing pendulum support.
2. Remove nut (1) from coupling rod (3) on both sides .
3. Pull coupling rod (3) out of anti-roll bar (2) on both sides.
4. Remove bolts (2) and detach anti-roll bar from subframe.
5. Place thrust piece (for removal)VAS 6779/1(item 1) on bonded rubber bush with flat side (arrow) facing in direction of travel.

6. Press out both bonded rubber bushes simultaneously until upper bush (2) is visible in aperture for pendulum support (arrow) in subframe.
7. Visually inspect outer ring of upper bonded rubber bush (2).
8. Using a chisel or similar tool (1), break out an opening in outer ring of upper bonded rubber bush (2). [Note: This step is necessary to prevent the outer ring of the upper bonded rubber bush from tilting sideways and catching in the aperture for the pendulum support in the subframe.]
9. Press out bonded rubber bushes completely (both bushes are pressed out together).
10. Bolt together both bonded rubber bushes hand-tight with original bolt (the two cut-outs (arrows) must be exactly above each other).
11. Insert bonded rubber bushes (1) into larger diameter of funnel VAS 6779/6(item 2) (with bolt head facing upwards).
12. Align bonded rubber bushes (1) in funnelVAS 6779/6(item 2) so that cut-out (arrows) is exactly in line with recess (A) in funnelVAS 6779/6(2).
13. Using workshop pressVAS 6654, press bonded rubber bushes into funnelVAS 6779/6 as shown in illustration until thrust pieceVAS 6779/5 reaches stop.
14. Insert mounting ringVAS 6779/10 and counterhold toolVAS 6779/7 on subframe. The cut-out in mounting ringVAS 6779/10 faces forwards.
15. Fit insertVAS 6779/7-1A with guide plate (item 3) in opening for pendulum support in subframe and secure to counterhold toolVAS 6779/7.
16. Screw threaded spindleVAS 6779/2 into counterhold toolVAS 6779/7.
17. To assist assembly, make a marking (arrow) in centre of raised section on subframe.
18. Attach assembly toolVAS 6779 to subframe as shown in illustration.
19. Press in both bonded rubber bushes together.
