the truck in question is the truck I use at work, 2001 Chevy 1500 4x4 with the 5.3, its pretty beat up but its one ofthe better trucks we have when it comes to reliability and it runs great. It just turned 184k miles and I assumed it never had the rear diff serviced(I'll be doign the front and t-case soon). I drained the fluid, pulled the cover off, cleaned the magnet, and scraped the gasket off, torqued the bolts to 15 ft lbs then 30 ft lbs and filled it back up and it was fine. Later during the day I saw that it was dripping, so I pulled it back off cleaned the cover and axle housing mating surface again, and a day later it was still leaking. I used a Fel Pro gasket both times. This last time, I used Permatex Gear Oil RTV in the green tube, I didnt use a bead, i put a solid layer around the cover and the bolt holes, let it set for 20 mins, then torqued to spec,still has a slight drip. Should I go ahead and try a Lube Locker gasket? If that doesnt work then I'll be out of ideas. Any help is appreciated
