mjeff87 Posted October 8, 2007 Share Posted October 8, 2007 Finally hung the D44 under the MJ today. Put it in SUA for now, to run it around a few hunderdt miles to break the gears and bearings in (then I'll SOA it). Good news is it went in well, and runs nice and smooth. Powertrax is virtually invisible, so long as I don't hit the gas around a sharp turn :D Bad news is that the D44 pinion is exactly 1" longer than the D35 pinion......I've only got about 3/8" travel in the slip yoke. Once I SOA it, the driveshaft (stock, 47") will be perfect, but for now it's not so good. I've got a spare shaft (thanks Nate!) I'm gonna take up to a shop tomorrow and have cut down. Jeff D44 under, finally Image Not Found not so good.... :oops: Image Not Found Link to comment Share on other sites More sharing options...
HOrnbrod Posted October 8, 2007 Share Posted October 8, 2007 Looks good Jeff, except for the 3/8" :roll: of slip yoke travel. Packed in there pretty good. You could always cram a crap load of rocks in the bed to pull the shaft out a little. Experiencing any driveline vibes? Link to comment Share on other sites More sharing options...
mjeff87 Posted October 8, 2007 Author Share Posted October 8, 2007 Smooth as a smacked baby's @$$, I'm quite surpised actually. For search purposes, a SWB MJ with a 2.5/AX5 and D44 requires a 46" driveshaft.... When Pat welded on the SOA perches, we set them to the same angle. Hopefully it'll be just as smooth when the springs are on top. If not, I can add shims. Link to comment Share on other sites More sharing options...
jtdesigns Posted October 8, 2007 Share Posted October 8, 2007 ok I'm clueless. What does SUA and SOA stand for? Link to comment Share on other sites More sharing options...

If not, I can add shims.That is not likely to work. Every SOA that I have done, even with a CV shaft, needed to have the pinion rotated up anywhere from 2-4 degrees. You will probably have to re-position them or use shims. Link to comment Share on other sites More sharing options...
mjeff87 Posted October 9, 2007 Author Share Posted October 9, 2007 Had one of my spare shafts cut down 1 ¼” today: Image Not Found Image Not Found Got the slip back I needed: Image Not Found Link to comment Share on other sites More sharing options...
TNT Posted October 9, 2007 Share Posted October 9, 2007 You should probably pick-up a YJ yoke so the shaft doesn't bind when drooped. Either that or grind your stock yoke for extra clearance. The YJ yoke is slightly longer and your shaft has enough slip for it to work without binding. Right now IMO it's about 1/2" out too far. Link to comment Share on other sites More sharing options...
Duner Posted October 9, 2007 Share Posted October 9, 2007 I hope your ok on the 47" I had mine cut to 46.5 and it fits the d44 soa setup perfect but I do have the 4.0 and the ax15. Link to comment Share on other sites More sharing options...

I have a YJ yoke (somewhere) I thought about putting on, but that yoke is riding at the same distance it used to before I got it (judging by the wear mark on it). I'm only running this setup on the road now to break the new gears in. Link to comment Share on other sites More sharing options...
Pete M Posted October 9, 2007 Share Posted October 9, 2007 While we're on the subject, I've got a Dana 44 swapped into my 90 and the driveshaft is also a bit too long now. I've got a 4.0L/AX-15 combo so in theory, I should be able to find a 4.0L/AW-4 driveshaft and it should be perfect due to the AW-4 being about an inch longer than the AX-15, yes?

mjeff87 Posted October 10, 2007 Author Share Posted October 10, 2007 That sounds plausible. Maybe someone on here is running that combo and can measure for ya.... *side note* had my first experience with the new locker in the rain this morning on the way to work......that was interesting ;) Link to comment Share on other sites More sharing options...
