My gut tells me it might be time for a new shaft. I wouldn't want mine to be stuck preventing travel every time the springs expand/contract. Heck, my jeep varies 1/2" just between an empty and full tank of gas and would think the splines should feely slip in and out to prevent a bind. Sorry I don't have any other advice.

 

You may have put the driveshaft back together out of phase, or in-phase, but 180 degrees out. Nonetheless, a DS that has a slip joint that does not slip is a problem. That slip joint should slide in and out very easily so that it can adapt to length changes as the rear axle moves up and down. I suppose developing a leak in the SYE could have been a sign of this, but it's better than the case breaking from a fused driveshaft jamming into it when you stuff your axle.
You could take your drive shaft to a driveline shop and have it balanced, but then you'd still be stuck with a balanced DS with new components that will not slip at the slip joint. Honestly the best bet is to measure your set-up accurately, and get some place like Tom Wood's Driveshaft or Tatton's ship you a new CV drive shaft.

 

Thanks for the advice guys , i think I'm going to pull it off again hope i can get it apart it just try to keep working it lose. I packed it full of grease idk how it can still be this stuck !

 

too much grease can keep it from collapsing. get it apart again, and clean the splines really good.
might even try a small flat file on the splines. every one i have had was tough to move, but a winch was not needed.
usually a few taps with a hammer and it would move. get it spotless, put it back together, see if its any better.

 

Well i pulled the shaft today and bet the leaving hell out of it again to get it apart. I didn't try no grease joe but i did try cleaning it completely. Sprayed everything down then cleaned out each spline with a flat head screw driver, resprayed and then sprayed it down with a garden hose. Once i got it what looked to be damn near spotless i covered it in anti-seize and tried again...... i pushed it about 2inch on to the shaft and its was frozen again. I didn't think driveshafts when bad ? Maybe it got bent some how , idk ? confused . I'm now driveshaft shopping any recommendations? I'm poor and on a budget haha i see tom woods has one for 255, that seams a bit cheap though. i paid over 130 for the centering kit and u-joints in my driveshaft now

 

I've heard mention of Carolina Driveline and seen some good reviews of the shafts they build. Not sure what the cost or how close they are to you, but an option to check out maybe.

 

Iv been looking at Tom wood shaft for 255 on 4x4 group buy or read great stuff about tatton on eBay too .

 

I had the same issue wiht a drive shaft I got years ago. They used that blue teflon crap or whatever on the splines and there was no grease fitting on mine. I repalced my entire shaft with one that had lube points for both the centering ball and the shaft itself.

 

Carolina drive line, tatton, tom woods, or even a local drive shaft shop could help ya out.
I would see what a local shop thinks first. If they think its not fixable, then price shop.
Good luck!

 

I dealt with Tom woods directly. They were great and fast shipping answered any questions you might have. There's also Adams, Carolina drive line, tatton, or even a local drive shaft shop could help ya out.
