    My 208 is leaking from the rear output. How hard is it to replace the seal, should I try and rebuild it at the same time? How hard is it to rebuild a 208? My truck has 145k on it, and a fair amount of time in 4 wheel drive and has never been rebuilt. thank you

    The seal is real easy to replace. Remove the drive shaft, take a srewdriver and pry the seal out. Then tap the new seal in with a hammer. Sometimes the seals are in there really good, so you have to take a hammer and tap the screw diver between the seal the the transfer case.

    I've replaced my 208 seal twice, first time it didn't go in strait and leaked, second seal it worked fine.
    It's easy be sure to park up hill so "t" fluid wont leak out, pull shaft out. Then pull gasket, and tap in new one with a rubber mallet. Should take only 10 minutes.

    Ps. You shouldn't have to worry about rebuilding the case, just keep up the maintenance.

    Shouldn't I park down hill to keep the fluid from leaking? Its the rear output that is leaking. Just wondering?

    Park with the front pointing downhill. I think he meant that you need to have the back up higher than the front.

    I paid $4 and change for mine from Napa - put a light coat of RTV or Permatex #2 around the new one before you seat it, and it will stop any possible leaks, and also make it easier to change the next time.

    Ya I ment park with the front down ward. And that is a good tip using RTV.

    Take your time putting in the new seal. GOOD LUCK.
