Front Diff Service

[peeweesp]

Hey guys Just did a front diff service on my 2014 Sierra which is super easy. But when trying to buy the Orings for the Fill and The drain plug the dealer couldn't find them called out anywhere. Anyone Have part numbers for them?

You might just measure/cross match them at a place that sells o-rings (easy in a bigger city, online if your in a smaller one).

 

Did something happen to the o-rings when you did it?  They should normally last through multiple removals/reinstallations....
