Post 20 & 27 I explained how to drop the Sub Frame assembly. If you are going to do just the Trailing Arm, why not just replace the TA Bushings and the Sub Frame bushings. really not that big a job, Now that I did it once. seemed a lot harder when I was reading through a bunch of threads.
Bottomed out
there has been a few threads where the Arms have bent, and the shock has broken through. think one collapsed. 2 I remember where the are is welded to the end piece, it rusted and cracked enough to let it sag.
