Need some diff help!!

[lx4life]

Oh one more thing there was NO sealant on the diff when I split it I wonder why that is. The only reason why I was taking it apart was to fix a small leak on the diff. Is that normal? Also what is the best sealant to use for a sealant cause I have RTV Black but I have heard not to use that cause the synthenic oil will eat it up.

I use the red hi temp one, but the black one is good to.

Hi it is a c" clip if your looks like a u" buy 2 new ones and Differential Carrier Assembly Case Mating Surfaces Sealant GM P/N 1052942 or any good RTV but make sure you read the directions on how long to let it sit before you put the halfs together.

Use a small file and clean any burrs around the c-clip grove and on any splines. This will make it easier to remove again if needed. Use anaroebic sealer on the case halves not sure if that is the part number twr has cause i dont know the part number off hand. If yu use silicone it will push out and eventually leak

Hi Humtech, that gm part # is anaroebic sealer, that is what gm uses on the case halfs in the USA, canda has a different part# but same sh-t.

Not to stir anything up or anything but since GM is not in the business of making sealant (we found out whats that all about with DIII episode) and it didn't work the first time when they sealed it, why would you expect a different outcome using a GM part#... again.
