My 2005 grand cherokee had the real seal leaking. When I took it in for service, they "found" the transmission seal leaking and fixed that also, this was not noticable prior to me taking it in. The next day fairly large muddle of tranny fluid on the ground. Now the Tranmission adaptor plug needs to be replaced. Thankfully I bought the extended warrenty when I purchased the vehicle and only had to pay a $100.00 deductible. Had a 2000 grand cherokee with 156,000 miles and the only problem was a fuel pump!?!? What happen?
Rear main seal leaks.

Took vehicle in to get new tires and was told that the Front Pinion Nose Bush is wearing out and needs to replaced. Received quote from dealer to fix. Thinking this way too low of mileage for this to happen.
