For the last couple of weeks, I have been hearing this irritating squeaking noise coming from the rear of my car. Each time I hit a bump, no matter how large or small, the car squeaks. I acknowledge that it is getting colder out, but why did it just all of a sudden begin squeaking? I need new rear brakes... I know that. My rotors have been ground down once so I could put off buying new ones for 6 months. Could that be the issue? I read in a prior post that this may contribute to the problem. Also, could it just require some lubrication of joints that have become too dry? After all, the car is almost 8 years old... I just don't feel like paying hundreds of dollars to replace my springs and struts and other stuff. Any help is appreciated. Thank you.

 

Same problem hear lemme know what you find out I'm going to lube everything up soon and see if it helps

 

Spring Isolators, shocks, shock bushings, control arm bushings. The cold weather affects the rigidity of rubber parts which can attribute to the squeak.

 

Its probably the control arm bushings... I don't believe they can be greased. I'm sure you could try to use some oil on them but i doubt it will do much.
