[QUOTE="swshawaii, post: 1041761, member: 67547"] [USER=64702]@blert [/USER] FWIW, I have the same 3:73 open "46" axle code. I also found milky colored gear lube when I removed the cover at around 60,000 miles. Man that stuff STINKS. I don't "believe" it was ever submerged in water. Magnet had typical soft grey colored sludge on it, but no large metal shavings. Decided to add a T/A Performance (Moser 7106) 8.8 cover simply because it looked cool and nothing more. Keep trying to convince myself the small fluid capacity increase and the drain plug made it worth the $150 expense. LOL Also used 75W-90W hoping for slightly better MPG and the fact I don't tow.
