Solutions for the repair of rear subframe bushing mount points for the E28?
It's a long title, but it's a big problem. Has anyone had any experience with repairing rust-out of the formed sheet metal underbody section that helps locate the subframe bushings. In my otherwise beautiful and mechanically sound '87 535is, this condition threatens the life of the vehicle.
My experienced BMW mechanic has never seen this condition before. We are ready to try and make a fix. Has anyone heard of a weld-in repair kit for the sheet metal bushing beds?
The solutions seems to be that we must cut out the old sheet metal section and weld in a new section. The bushing pins are still there and the heavier cross section they attach to is OK. The bushings are shot. They will come out and be replaced, possiblyalong with the old pins. We need to come up with just the underbody sheet metal for that area (both sides) or build something else that will cup the bushing accurately and securely in place.
