Well, I tore my rear rotors off to do the brakes and I am wondering if I should tear into the rear bearings for a replacement or repack or leave well enough alone. Neither side rocks from side to side but the drivers side has a slight back and forth play, maybe 1/8" and the the passenger side is about 1/16" back and forth. I have read many places where these Toyota bearings on this vehicle can go 300K with little problem. I don't want to break any seals if it is not necassary though I do have the new bearings as spares in my posession. Just don't like to break the seals if it is not needed. What say you?
