Title: Omega Rear Coil Spring Change
Post by: Marks DTM Calib on 08 February 2007, 12:55:03
First, chock the front wheels, release the handbrake and put the vehicle in neutral, jack up the rear of the car and support on both sides with axle stands....do not place these under the trailing arms as these need to be able to move for this job.
Reach up by the rear of the diff and un-clip the ABS sensor connectors from their mounts.
Now remove the bolts securing the bottom ends of both rear shock absorbers and pop the shock bottoms out of the recess in the rear hub assembly......note....the trailing arms may well drop at this point so be careful.
Place a jack under the base of the diff and then remove the four bolts which secure the rear of the sub-frame to the floor pan (two of these can be seen in the pic above of the ABS sensor connectors).
Its worth considering drawing or scribing a mark around the mountings so they can be fitted back in the same place to avoid rear alignment issues (minimal risk), reality is that you can normlay see the position in the dirt around this area....so this is optional
Slowly ease the jack down whilst watching the brake lines and wires to make sure they don't snag...the passenger side drive shaft will touch the exhaust at which point you can now pull the springs out.....
Fit new springs (in pairs!) and re-assembly is the reverse of removal....
