Rear Trailing Arm

Rusty trailing arm = death wish

How to get the 280CE approved for the road? Change the rear trailing arm since it is rusted. Not allowed to weld this critical part. So it is obviously number one priority. One can say that Christmas this year came early. I have been searching for a good used one as this for a long time and this particular one I got quite cheap compared to a new one! It even came with a good wheel bearing and the handbrake shoes with the cable. New trailing arms for the W123 from a Mercedes dealer can cost up to 3000$ and I was not up for using this amount of money when there are alternatives.

It weird that this one rusted and the other one is completely fine, also it rusted on a smooth curve and not on a edge.

Like new this one! I painted it and changed the rubber bushings as well, however needed a workshop to put the new bushings on. I don’t have a hydraulic press in my basic workshop.
