    the seal where my driveline slides into the t-case seems to be leaking. what is this seal called and what is involved in changing it. just a seal puller or is it more difficult than that. thanks.

    what t-case is it??
    241/208/203/205

    they should all pretty much be the same if you have a slip yoke. just pop it out, carefull not to damage anything. get the number off the seal and take it to your local parts store.

    if it's a fixed yoke you have to take the yoke out first.

    i usually put a very slight (paper thin) coat of silicon around the seal. it'll act as a lubricant as it goes in and sealer when it dries.

    Not sure what happens on the other t-cases, but when my 205 t-case to tranny adapter seal failed, allowing the t-case to overfill, the seal started to leak.

    Make sure the t-case fluid level isn't too high before replacing a seal that may not be the real problem.
