tpsnyder 03-30-2005, 05:45 AM I have a 2001 duramax with about 90,000 miles. My right rear wheel has a film of oil on it, i assume it is differential fluid. I'm sure it isn't brake fluid. I changed the differential oil at about 50,000 miles. Can you tell me the possible cause and fix for the leak? Would this be covered by warranty? Thanks GMCSID 03-30-2005, 10:59 AM If it's not brake fluid then it is a leaking axle seal. If you have an extended warranty this should be covered depending on your warranty. tpsnyder 03-30-2005, 11:45 AM Thanks GMCSID, I have the 100,000 standard warranty on engine and drivetrain, nothing else. Do you know if that warranty covers the leak? Terry GMCSID 03-30-2005, 01:23 PM If you just have the standard warranty then bumper to bumper is 3yr/36k. The 5yr/100k is just for the Duramax engine with a $100 deductable and only certain parts of the engine. An axle seal would not be covered under that warranty. | ||
