knocking sound from rear hello,
my car is making a knocking sound and i think it's coming from the rear. it sounds like shaking one dice in the dice cup. sometimes it's faster and sometimes slow. it only happens when i let the car decelerate from ~35 mph in overdrive or d. when i give a little bit gas or shift manually in second/first there is no knocking.
any ideas?
thanks,
nebu

This is the classic torsen differential "marbles in a can" sound. Either live with it, or you can try to shim the retaining pin a bit to cut down on the rattling. When the differential is not under load the paddle piece rattles around making noise. It's just the design and there's nothing wrong with it. I think some are just noisier than others.
