never leaks on floor but there is definately a fair amount around the diff where the drive shaft comes out on both sides, 2001 with 48k miles, do these seal leak, need replacement often, ideas on how much to replace?
I just had the seals replace on both sides at 45K miles. Not dripping on the floor but had them changed while still under warranty. I think this is common from what I have read on the board. The seals are less than $10 each.
From experience, don't let them get to the point where the gear oil is getting thrown on the differential bushings. The gear oil will break down the rubber in the bushing causing it to collapse-you will then have some big clunks while shifting as the differential is bouncing up and down.
