I have started to notice noises that I attribute to excesive differential clearance.
When shifting up I can generate a "clunk" type sound. Also while driving I can generate the same thing by feathering the throttle. I can eliminate the noise by being excessivly smooth on acceleration. I seem to be able to duplicate the sound by raising the rear wheels off the ground and rotating the rear tire. My questions are: How is the pinnion/ring gear clearance set? Can it be adjusted with the dirve train still in the car? How long can I let this go? |

Lay down at the back of the car, reach underneath, grab the axle and try to bang it into the transmission, then try to bang it into the wheel side. If you hear it hit, that CV is shot.
There has been some debate as to this technique, but I think it works and I've used it on multiple cars. |
