Look around for ptu threads. There are procedures and tips on how to change this. Alot of dealer service will quote the 'lifetime' fluid and not want to change it. There is some DIY tips and even a drain install for that unit. most rear diffs are-- open the housing drain fluid. replace gasket (usually specialty rtv sealant) and refill. All this stuff is in posts on here somewhere
