Procedure:

1. Chock the front tires and lift the rear end of the car onto jackstands. (Put your jack under

the differential housing so that the two lift pads are available for the stands.)

2. Remove the tires and place them under the car, so that if you manage to knock it off the

jackstands you won’t get crushed.

3. Use a felt tip pen to mark the eccentric bolt and swing arm so that the car will be mostly

aligned when you reassemble things:

4. Unbolt the brake caliper from the wheel carrier and place it on top of the wheel carrier to

prevent the brake hose from getting pulled on. This step also makes room for the swing arm

in a future step:

5. Climb under the car and take a look at the suspension to get yourself acquainted:

6. Using your 24mm socket, ratchet, and larger breaker bar, remove the nut from the end of

the eccentric bolt. You’ll probably have to use another wrench to hold the eccentric bolt to

prevent it from turning. Once the nut is removed, use your 18mm socket, ratchet, and

breaker bar to loosen – but do not remove – the bolt as shown. This bolt keeps the integral

link in place while you remove the eccentric bolt:
