hi guys, i noticed today on my way to work a strange noise that i haven't heard before, it seems to happen when im driving along and i completely take my foot off the accelerator, its kind of like a very low pitch bumping noise. it sound like it coming from the back of the car but im not sure.

what do you guys reckon?

Check tier pressure if it's off on the back from one side to the other to much you could be putting the rear end in a bind. If that's ok when if ever is the last time you had the fluid changed in the rear end (do a milage check). If all is good there check the drive shaft for movement.

 

whens the last time you changed your diff fluid? how many miles are on the car? is it auto or stick? more info on the car would be helpful but ill try to help anyway.... it sound like my car when i do the same thing with traction control on my car does it all the time but i have lots of mods done. I would change the fluid to some full synthetic amsoil severe gear or Redline. What ever fluid you use make sure its a quality GL5 with limited slip additive. takes just under 2 qts. i would start there and see what happens.
