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? |

Joe, you are right as well (thanks for the honorable mention (IMG:style_emoticons/default/wink.gif) ). To check CVs you can jack up one side at a time and rotate the up wheel for and aft. You should not hear or feel a click after some motion (clear?). I REALY doubt your ring and pinion are that far gone (IMG:style_emoticons/default/biggrin.gif) If so you would be in a worse shape. However, if the roller bearing on the pinion shaft goes, you can have some symptoms of the clearance changing. But, I am thinking that the simplest explanation is what Rich suggested. Check and get back to us so we can see what to do next. |
