I'm sure your advise on replacing with a good second hand one is the way to go. Does anyone have one at a good price?

B, you might try some of the recyclers on eBay. They may not have a trailing arm on their listing, since it's not a high-demand part, but give them a call.
I have had good luck with Ideal Auto in Chicago 773-509-9999 (Alex).
also SoCal dismantles a lot of 126's.

I found new rear subframe bushings to have more effect on rear ride ht that any other thing.
Also, the 300SE has a 9.5mm rubber shim above the spring. This can be replaced with the next thicker spacer (14mm, or even 19mm) to raise the ride ht. I did the subframe bushings and the 14mm spacer and she came up a couple inches, just right.

I have a trailing arm taken from a 1991 300SE which is my car. The car needed a wheel bearing in that arm and it was cheaper to replace the whole arm than to find someone who would do the wheel bearing. I have that trailing arm for the right rear if you would want to replace the wheel bearing.
I would sell the whole arm for $20 plus shipping. Let me know. In the meantime you can check out the replacement bearing cost. BTW, the car only has 97,000 miles on it.

What state are you in?

I have some W126 trailing arms.

I'm in northern Illinois, about 100 miles west of Chicago.
