Make: GMC
Model: Yukon (Automatic, 4WD)
Year: 1999
Mileage: 140,000+
Engine Size: 5.7L V8
My GMC service manager said my Yukon has a front pinion seal leak and a transmission tail shaft seal leak. What are the indications of a leak or what might some indications that I have a problem that needs servicing since I never see any evidence of leaks on the ground or in my garage? Can these problems be easily resolved by a non-mechanic like myself or better left to the experts?
