2006 Cadillac SRX Q&A
2006 Cadillac SRX Question: DIFFERENTIAL SEALS
OK first there's the pinion shaft seal where the drive shaft is located and the labor to replace this seal is 2.8 hours plus the seal (dealer item) then there's the axle seals on both sides and the labor for both is 1.9 hours plus the seals (AC Delco $20) each. But I would get another opinion for a different shop here http://repairpal.com/directory?address=36571&car_brand_names=Cadillac - hemicuda
The rear axle pinion seal may leak causing fluid loss and possible internal rear end damage. Replacing the faulty seal will commonly correct this concern.
