The old system was removed and the trailing arms severely damaged to accommodate a horrible hospital job using std shocks.

The unknown for me is the compression of the springs.

It sounds from your post that it was a piece of cake.

Please walk me through it if you can, I would love to know how you did it, and what tool you used for the compression itself.

I watched the wrecker take the arms I now have, off its previous location and that seemed to be easy to do in reverse.

Thanks

Below in the first pic is a Copy that works of the best, safest and easiest to use spring compressor (and it works on front and back springs). However, the High quality version is around $265 (eBay prices) and this copy is around $190.
I used a set of Generic ones like the set in the 2nd picture and while I did use them and manage to change out the Trailing Arm I cannot say it was entirely safe and it was not easy. Partly because I could not get them spaced opposite each other and still be able to tighten them to compress the springs.
And, buy the way never use these Generic ones on the Front Springs as the front springs must be 3 times or more stronger then the rear. I know as I tried it and bent up my Generic Spring Comoressors.

Another option is to make your own:

The above homemade one may be the only other safe solutiong to the job.

I'm working on a 1983 240d.
4 speed car.
The left rear swing arm is rusted out and needs replacement.
I bought a clean used arm but the outer arm bushing is bad.
I got a new bushing and installed it in the arm.
I see the rear subframe needs to drop some to get at the outer swing arm pivot bolt loose and out.
I'm not sure how to correctly deal with the spring or maybe both springs.
Any advice appreciated.

Replacing the Rear Shocks & Springs
on the W126 1985 300SD

What size is the flare on the hydraulic line into the damper?

This has to be one of the worst tasks to do! Hydraulic fluid dripping on you and all over the place, so slipping when trying to traverse and making the socket not get a grip.

Thank you all in advance! :D
