put a new power-lok diff (the stock one) in my step fathers dana 70 and now whe he turns sharp the clutches shudder, makes quite a bit of noise. is this normal for a new diff and do they just have to wear in? he went with a larger diff pan and added about 1 1/2 bottles of limited slip fluid to compensate. any ideas?

Edit: SORRY!!! wrong forum

 

i dont think thats good it sounds to me like something is binding up in there
