    I am in the process of replacing the shift shaft seals. I got the old ones out fairly easy. It's now time to install the new ones. I attempted to push the new ones into place through the ID of the thrust washers. That seems like I might be asking for trouble. The new seals really aren't that pliable. (These are the cupped style; original part numbers. Not the quad seal.)

    My choices are to grease the outer surface of the seal and push them into their seat with the thrust washer in place. Or...grind the peened raised surfaces, remove the thrust washers, and then install the seals. (I would then have to peen three new points....not sure if that is feasible.?)

    What's conventional wisdom say?

    Kevin,

    Sorry I have no suggestion, as I used quad seals plus a very tiny seal to hold the quads more securely in place on my 308. Not a single drop in over a year and a half.

    Just asking, Why put in known "OEM junk" when the quads are sooooooooooooooo much better?

    Hi Mark-

    I decided to use the OEM seals based upon various posts such as the following:

    Are the Quad Seals more pliable, easier to install?

    oil tight going on 4 years.

    Kevin,
    I've done them both ways with good results. I like the convenience of just pushing them in but there is a certain peace of mind removing and staking the washer back in place. The latter also allows you to use some oil resistant silicone to "seal the seal" to the case after you clean it. I use the Ford grey stuff for diesel oil pans.

    The outer seal is easy to stake, the inner (between sump and gear case) is not so easy to stake just because of room. I'd test your tools and technique before removing the inner seal holding washer.

    Kev,

    I have a 308 so their MIGHT be a difference.

    I have to admit I just put the quads in the groove. They wiggled back and forth a bit and a friend on another forum sent me some tiny O-rings and fit inside the quads groove that meets the thrust plate. They no longer wiggled.

    I then oiled up the shift shaft took my time and "in" it went thru the first seal. Oiled it agin and it slid past the second seal.

    It is noticeably stiffer to shift than with the EOMs that were rotted like nobody's business but I have no problem with that.

    If the OEMs are working as others have posted and you spent the money, I say, give it a shot.

    Best of Luck.

    Oh, I'd probably change out the silent block "...while your there."

    Rick-

    What kind of tools did you use to stamp the peen? I think the sump housings are die cast aluminum, which would lead me to conclude that the surface is pretty rigid. Would an air hammer be overkill?

    Kevin,
    when I restaked the washers into the sump, I just used 1/4 inch chisel and worked from about an 1/8 inch out towards the center of the hole with the chisel blade lined up to the center as well. (radially??). I angled the chisel so as to drive metal towards the center of the hole. Make sense?

    Yeah, I'd think an air hammer would be overkill. It doesn't take much to deform enough metal to hold the washer plate in place.
