Rear Suspension

Ok, there are a lot of similarities with the front, so I'm going to skip some details.

1) Put the car in 1st gear and put blocks under the front wheels so the car can't roll forward. Jack up the back end and put the car on stands in the rear pinch weld supports. Remove the wheel.



2) There are two bolts you will be taking off: one connecting hub to LCA, and one connecting strut to LCA. Remove the hub one first. It will help to use a jack under the LCA to relieve the pressure so the bolt can be slipped out. The LCA is threaded so there is no nut on the bolt.

Once the first bolt is out, lower the jack again and the 2nd bolt at the strut is easy since there is no longer any downward pressure. If you have a rear sway bar, you'll need to detach it from the LCA.



3) Pop the trunk and remove 3 plastic clips (I don't have a picture). There are removed by carefully pushing the center in a tiny bit, then pulling the whole thing out. (to replace the clips, you need to remove the centers from the outer rings, place the outer rings in the hole to hold the side panel carpet up and then insert the center to lock into place.) With the clips removed, you should be able to pull the carpet down to reveal the rear tower. Using a 14mm wrench, remove the two side bolts but don't touch the center nut.



4) The strut should be loose now. Push down on the LCA and carefully remove the strut/spring assembly taking care not to rip the brake lines, etc.

5) Disassemle and reassemle just like the front suspension.

6) Replace and hand tighten the two top tower mount bolts.

7) Push down on the LCA and insert the 14mm bolt to connect the strut to the LCA. The bolt should go in easily because the LCA is loose. Screw in, but don't torque yet.

8) Put the jack under the LCA again and jack up the LCA until the hole for the bolt of the hub to LCA line up. You should be able to easily slip this bolt in. If not, you don't have it aligned properly. Readjust the jack till you get it aligned. Screw the bolt in but don't torque.



9) Now jack the arm up higher until the car just begins to lift off the stands. Torque:

Both LCA bolts: 40 ft-lbs
2 Top tower bolts: 36 ft-lbs

9b) Because the rear suspension is a Macpherson design, lowering the rear causes negative camber. If you are going to at a camber kit or use the washer trick, now is the time to install it.

10) All done!



Next up.... the washer trick...
