Hi, I’m new to this group. I’ve had my Equinox for almost 5 years now and about 2 months ago it started making this really loud thumping noise from drivers side rear whenever I would hit a bump, go over train tracks etc. My fil thought it was the hub going out, so as we were replacing that we noticed the frame right where the trailing arm connects to it is rusted out pretty bad…I don’t want to junk it because it’s still a good running car, but obviously it is unsafe for the road…I guess I’m looking for suggestions on it! Thanks
