Rear end leak?
Just looking under car this morning and noticed a little puddle of something. It's a clear petroleum feeling product. Never noticed it before. Only have 2100 miles. Any comments? :crazy:

Re: Rear end leak? (denali)
Assuming you looked inder the rear of the car, it "might" be diff fluid. Can you put it up and do a visual check on it? Clean of any crud, especially from the sides of the diff, and then just keep an eye on it for awhile. Were you driving "in excess of the posted limits" recently? Sometime the diff will vent some during a hot, high speed run. :D

Re: Rear end leak? (denali)
Most Likely a differential leak. Usually it leaks from the driverside rear differenrtial housing. I have a 99 with 8500 miles when mine started to leak out of warrnaty. GM did nothing to stand behind it even though it is a know problem. Repair cost at a reputable dealership $500-600 including replacing all the seals. :boxing
