– Starting work:

I got the car up in the air, one rear wheel at a time. Remember to replace components on BOTH sides of the car whenever dealing with suspension.


– Remove brake caliper

Remove the caliper with a 16mm socket, by removing the two caliper bolts located on the rear of the unit. Once removed, place it on top of the hub assembly behind the rotor/disc shield or hang it from a belt/rope from the strut spring. Do not let it hang by the brake line.


Just to skip ahead for a moment to comment on the alignment. The alignment of the rear end is adjusted via the large eccentric bolt that you will be removing. This bolt has a unique off-centre head that allows you to adjust the camber of the wheel. I used white out/tippex to mark the existing position of the bolt before I removed it.

Here is a pic of the bolt removed, however note the 3 dabs of white; these were painted on the carrier as you can see, and over onto the bolt head that was removed. On re installation, I simply lined up the lines to the millimetre and it was perfect:


Whilst an alignment is recommended after this job, I got my car tested in the annual National Car Test the following day with no alignment, and the results were spot on, less than 3% deviation.
