If you do a search you'll probably find hours or reading on pinion angle. I also think ther eis a tech tip here about it as well. Just check the angle you have. I believe the angle should be about 2 degrees negative. Some say check the angle on the engine at the starter, some say transmission ect ect. I check mine with the starter then go to the rear end and set it.
I think the "officially" the angle should be between 1 to 3 but I'm sure someone with a better memory than mine will chip in here. Good luck.

I'd rather walk and carry a Chevy hub cap than ride in a Ferd.
I can explain it to you, but I can't understand it for you smile
