    I have the "saginaw" type front driveshaft. The rubber/plastic seal that holds in the grease where the shaft slides in and out of itself is bad. No one I know has ever tried replacing one. I was curious if anyone here and ever done this and if they were able to find a replacement seal. Obviously the two parts of the shaft would need to be marked to make sure it went back together the same way since it's balanced. But I'm not sure exactly how it actually comes apart. I'm hoping someone might be able to shed some light on the subject. :)

    Shock boots

    Never tried to rebuild that seal.
    I did have a problem where I was wearing out that Spline pematurely because the Shaft angle would cause water to ride down and in past the seal. I put a Boot over it from a Rancho Shock. Tie wrapped both sides, for $5 bucks It has worked well for me.

    That's actually not a bad idea. I went to the local chevy dealer and special ordered the seal for 12 bucks. They also printed off a parts diagram of the driveshaft for me. There's actually more to the inside of the shaft than I had expected. I think I'm still going to attempt the seal replacement though. If I can't get it, the boot idea is a cheap solution.
