Own a 2002 Silverado with 381k miles.
Discovered a differential oil leak at bottom of cover.
Previously replaced the gasket less than a year ago.
Drained the fluid and removed the cover to inspect.
I had an extra Genuine GM gasket handy so I cleaned both mating surfaces really good and replaced the gasket using NO RTV.
Filled the differential with oil and parked the truck on the street.
This morning I walked over to the truck and observed a small drop of fluid right at the bottom of the differential.
Now I'm thinking that the differential is warped and needs to be replaced.
I was reading on some of the GM forums that many have turned to gaskets made by LUBE LOCKER https://www.lubelocker.com/product/llr-g850/
but when I went to the website to look at the gasket I noticed that its pretty symmetrical in that it's round in shape but without any type of curves and contours.
The Genuine gasket by GM is circular in shape but has contours that follow and sort of match the mating surface.
I have been told to ONLY use gaskets that have the updated contours that allow fluid from the 3 o'clock and 9 o'clock openings to pass thru to the axle.
The wrong gasket will cover these holes that are located at 3 and 9 o'clock and will eventually cause the axle bearings to fail.
Just wondering if anyone here has ever used these gaskets by Lubelocker?
Should I just stick with a Genuine gasket and use RTV?
Should I replace the cover and gasket?
Going to need the correct torque pattern and torque values
Any advice is greatly appreciated
