Rear differential noise
I suddenly am getting a loud grinding noise which I assume is coming from the rear end gear. It is very loud while coasting (not on the gas). Approximately 200 miles ago I repaired a leaking pioin seal, which required removing and replacing the pinion yoke. I followed recommended procedures, including measuring the rotational force of the pinion to replicate the preload on the pinion bearing. I also replaced the fluid with synthetic and friction modifier. Well, my guess is that I got the pinion too tight or loose. I want to fix this myself. Where should I start? Should I get a complete pinion installation kit of try to get by with just a pinion bearing and crush sleve. Thanks for any advice. 99.5 F350 10.5 inch rear, Automatic Trans.
