I just installed 2 1" spaces on my front shaft and the vibes are terrible. I can lock the hubs put it in 2wd (so the shaft will spin from the axle tuning) and I feel no vive at all. As soon as I put it in 4wd and let out the cluch it gets really bad. Feels like it's comming apart. Even with 2" of spacers in I still can see 1 1/2" or maybe a bit more of the splines. Is this normal? I've heard many times that people need less spacer than that but I seem to need more. Also those of you that are tunning 2 sapcers on the shaft where do you have them? One at each end? Both an one end? Which end works best?
Also, does anyone know if a Toyota 1.6l DOHC will fit a 22r tranny?

Do you have any slop in the splines of the driveshaft?

Are you saying that before you installed the spacers, you had no vibrations?

Yes before the SOA and YJ's the front shaft had NO vibration at all. I do have slop at the splines but I think that it is because the splines are so far extended. Just a guess.

There's your answer :)

Also, did you make sure you re-installed your driveshaft halves clocked the right way? The driveshaft is balanced from the factory & marked to go together a certain way. If you seperated the halves, then stuck it back together out of sinc, this can cause vibe's too.

So my thinking is right? Sounds like the spline is overextended correct? I just wonder why my setup is any different that anyone elses with stock axles and TT YJ ML kit. Everything else is in the stock position...

According to the FSM, the drive shafts are match marked. That is, there are little centerpunch marks near the splines that should be aligned when the splines are properly aligned. After my SPOA, I had terrible vibes cause we got the two shaft halves off by 90 degrees , lined 'em up and the vibes went away.:D

Yeah, the indexes are all lined up. I even tried it 180* out. Just too damn short I guess.:mad:
