Ok... so I discovered that my rear trailing arm bushings are ripping and shot. Mechanic says $750 to fix (all the labor of disassembly and cleaning out the old bushing). So I'm looking for alternatives.

Has anyone tride making their own urethane bushing using 3M Window Weld (caulking urethane) to fill the bushing? Example:

This is a picture of a motor mount, but I'm thinking this will work for the rear trailing arm bushing too because it's not sollid.



BTW, if it turns out this doesn't work, can the urethan just be torched out? or what?

OR... has anyone installed urethane bushings to the rear trailing arm without removing the whole assembly?
