Hey H.A.M.B.'ers So I went to change the pinion seal on my 3rd member last night and think I my have an issue. The pinion nut was damn near frozen onto the pinion shaft. So I warmed it slightly and flooded it with my Fav Oil "Kroil" After that I was able to pop the thing loose but with a ton of force to loosen it up. So much for trying to figure out the torque on the nut. That was what I was trying to do. So That's out, but I did count the number of turns that the nut took to completely come off the shaft. Cleaned all the stuff up and then installed the new seal. I put the nut back on to where I thought the thing should be for sure but now I have my doubts.... I checked my lash with an indicator before I started this whole thing and I had 0.005" of clearance. Now I have 0.011" So I'm thinking that I have potentially crushed the sleeve on the pinion just that much more and now have added clearance. The strange thing to me is that I thought for sure the pinion depth was established by the bearing seating into the rear race, that should be in a fixed location in the rear end housing? That would tell me that the only thing the front nut can effect is bearing pre-load NOT pinion depth, and/or, gear clearance???? This will go to the rear end shop Monday but I thought I might ask here first to see if I'm totally missing something. Please Help, Robert M.
