Rear end squeak
First post here. The car is not mine, it'* my Father-in-Laws and I'm trying to help fix a problem. He'* got a 97 SSE that'* making a very loud squeak in the left rear. The car has around 140000 miles. 1st thought was bushings, but it seems too loud and excessive for that. 2nd thought was the rear strut, but again doesn't seem like the right kind of squeak for that. I'm thinking along the lines of a mount, maybe the spring mount, or strut mount? Anyone have something similair happen or ideas on where to start?
I'm on vacation and kind of limited on what I can do but would like to try and track this down. Thanks in advance!
