I did my first full gear install about three weeks ago. I driven the car three or four times and put about 30 miles on it, just to "break it in". I seemed to have a difficult time setting pinion depth using the Ratech tool, but I believe this is on me, not the tool. I also seemed to have a difficult time measuring pinion preload due to me using a click style torque wrench. That being put out there, here is my problem:
Gears sound fine as long as the drivetrain has a slight load on it. Gears do not clunk or click when initial load is applied. The only sound I get is when I am coasting. I get something between a howl and a growl, not really sure how to describe it. The sound goes away if I turn to the right, but not to the left.
I read that decel howling or growling is due to bad preload on input bearing, but the fact that it goes away with right hand turns makes me think this is not right. I am leaning towards a differential bearing, but not really sure. I have had a bad axle bearing before, but it growled during turns, not went away. Backlash was set to .010".
Someone point me in the right direction, please! I have a trusted mechanic who will redo the install for $150, but I hate being defeated by something.
Thanks in advance!
