Q. I have a Jeep Grand Cherokee and it has a squeak and bang coming from the back. When it was in for an oil change they looked at it but didn’t find anything. Would you have any thoughts about this?
A. The problem could be the rear spring insulators, these are rubber pads that are used to isolate the springs from the body of the vehicle. Check the pads and take a good look at the springs, with age some of these springs can break and cause the banging noise.
