New 4.10s quiet under load but loud on decell, why?
My buddy and I put a new set of motive 4.10s in my car. They are quiet while under a load like driving up a hill but when I push the clutch in to slow down they whine pretty loud. We had the pattern good and everything. We ended up with a .035 pinon shim and set the backlash to .008. It didn't seem loud at all when we got done with it but since the install I have put about 150 miles on it with no launches or anything, easy driving. What is the common problem that will make them whine while coasting?
