Re: Replaced pinion seal but did I do it right?

If there is a part you should consider replacing it is the pinion nut. They lose a lot of the locking characteristics on re-use.
Other than a very slight whine at highway speed it seems fine. It may be from the bearing but it's hard to say for sure. I can't feel any end play at all.

I'm hoping it lasts many more miles, but if I could find a complete diff with gears somewhere between 3.08 - 3.42 I'd like to swap it out. I don't need the 3.73s and it sucks gas like it's still 1974 when gas was $.32 a gallon. It's not terrible bad if I keep my foot out of it, but it doesn't take many squirts to drop the MPG from 10 to 7

I really appreciate the helpful info!
