Question type: Maintenance & Repair

Only when driving at 40mph and up I am
hearing a vibration/humm and feeling
vibration on the floor bored. Everything on
the engine checks as far as I can tell so I
looked at drive terrain. The rear diff seems
to be over heating and I'm not sure if it's
worth getting into with the short time I've

1 Answer


If the rear differential is running hot then it needs overhauled or it is too low on lube, and if that is the case it may already be too late anyway.
