Well, about the pinion...
So we finally got some snow on the Eastern Shore of MD and I went out with my neighbor whom I have been friends with since we were 16...
He is always giving me grief for sticking with my "old and busted" and he says his F150 is so much better...
Well, he got stuck in what we will call Lake Delmarva...
About 28-29 inches deep. So bad, his rear wheels were turning, but not hitting anything.
Anyway, after pulling him out, I must have really jarred something because I lost a UBolt on the rear axle...
Long story short, I have aligned my truck and ordered the Downey LSD with all 4 bearings... If there is still a problem, it won't be there...
Thanks for the advice everyone.
