Another AMC 20 Pinion Oil Seal Leak \"?\"
Dang it! I thought my differential cover was leaking, so went out and bought a new gasket. When I got under it to do some other work, I realized the pinion seal was leaking, and the oil was running down to the bottom of the diff.
It doesn't sound like changing the seal is too hard, but I have a couple questions for which I couldn't find answers through the search.
1. (The torque question) I want to get the torque on the pinion nut the same as it is now, but how exactly do I go about measuring that? I have a good dial wrench, but won't any rust or ?? on the nut make a difference in the torque reading before I remove it? Also, do I just measure how much torque it takes to get the nut to break loose, or measure how much torque it takes to begin to tighten the nut, then begin removing it?
2. I've read other posts that you have to also replace the crush sleeve at the same time? One post said the crush sleeve is behind the carrier, one said it's behind the bearing. Looking at different diagrams of the pieces of the AMC 20, I'm still not clear. Is it necessary?
3. I think I'm making this harder than it should be...
