the rear end? 98 MGM. Found small leak into the parking brake causing it to fail inspection. Axle Vent was clear and didn't hold vacuum.
Anyway I went ahead and changed out EVERYTHING(both sides) with Timken bearings and Motorcraft seals and vlv high performance 80W-90 (the dealership said they use that product if they are low on Motorcraft). When I took the car for re-inspection to the dealer the tech said he would have just changed the bad seal. He said solid axle bearings rarely fail if there is oil(don't really agree). Honestly the bearings looked pretty good, but had very,very slight bluing.. but for $20 a set it wasn't worth to send them back. Axle contact surface looked almost new, that was a good sight!
