Engine Mechanical problem
2002 Oldsmobile Bravada 6 cyl Four Wheel Drive Automatic 83500 miles
When we had our oil change recently we were told that there was " a small leak in the differential area". When I had our mechanic look at it he initially stated that it was minor but had to find out more. WHen I spoke with him again he said there were 2 seals that need to be replaced. It is on the drivers side and the pinion seal needs to be replaced -- $100.00 plus tax & labor and that the left had output shaft seal need to be replaced at $731 for the part only. He said it was more involved.
Help! What is going on here. We have not noticed any leaking on our garage floor. We are confused.
