Is the so called "Tumbling Rocks" noise that the rear end makes a normal sound for this car or is that something that is going to break soon? It only does it when you let off the gas as most of you probably know. Is there a special oil that I can put in it to help or do I just have to live with it, I don't have the money for new gears. Car is a 99 with 40,000 miles.

The Zexel Torsion rear differential will make some normal clunk on decel due to the worm gears moving inside.I assume you have a Zexel Torsion?
