I'm swapping my old differential for a 3.73. I pulled the old axle seals and they looked pretty good- the seals had been replaced with the newer style. I replaced the inner oil seals, but I think I wil leave the outer seals alone. They look pretty good. Is this a bad idea? They're only dust seals, right?
Also, should I replace the axle bearings while I have the axles out? Do they have to be pressed on by a machine shop?
Last, I thought I would replace the pinion seal, but when I pulled the yoke on the 3.73, pinion seal looks pretty recent. And it looks like there is no good way to pull the seal without removing the carrier. I'm thinking just use a speedy sleeve, and hope for the best. Should I go to the trouble of replacing the pinion seal while I have the opportunity?
Thanks for the advice.
