Drive shaft replacement options

[Dannyboy1966]

I have a 1986 GMC 1500 Sierra Classic. A week ago was under my old girl, and realized I had a bunch of wobble in the carrier bearing. So this weekend since it was nice, bought a new one and decided to get after it. I HAVE A PROBLEM, the shaft that the carrier bearing presses onto has worn away about 1/16th of an inch. The bearing was still spinning, probably why I didn't feel a vibaration, or hear a squeeling sound. What year's and options do I have as far as replacing it? I'm running a 350 with a SM465, and 373 rear. The part of the shaft I need to replace is 41" long 32 spline slip joint. Can't find a replacement anywhere.

We have a couple of good driveshaft fab shops in our area..you might try to find one local to you..they might can fix you up. These trucks are getting harder to find in junkyards so parts are not as easy to find either..

If it was mine, I would think about finding a bushing with the correct I.D. and O.D. and try it. It ran this long with a very loose fit so I'm sure a bushing could make it work even better; kinda like the bushings we put on harmonic balancers. If not, driveshaft shops build driveshafts every day for a couple hundred bucks.


Now that I think about it, the bushing deal may not work, oh well.
