jslamerman Posted March 28, 2006 Posted March 28, 2006 Ive got a shortbed commanche, thats now sprung over with an add a leaf. The driveshaft is WAY too short, leaving me with about an inch of spline engagement at the tcase. My question is, in order to try and avoid making a new shaft, what could possibly work for me?? I have a 4.0/ax15 combo, would a puegot/4.0, or auto/4.0 be any longer??? I have a shortbed, but I know the longbed would be WAY too log. If I have to do a new shaft, I'm going all the way, with an SYE as well................
jslamerman Posted March 28, 2006 Author Posted March 28, 2006 Actually. looks like a Puegot would be a little over an inch shorter!! Anyone have a rear d-shaft out of a 4.0/Puegot truck??? (shortbed)
Pete M Posted March 28, 2006 Posted March 28, 2006 I had my 2wd shaft cut down to the right length for my 4wd conversion. Cost me around $30. Jeep on! --Pete
jslamerman Posted March 28, 2006 Author Posted March 28, 2006 That would cost like 100 bucks here!!! I hate the northeast............
pingpong Posted March 28, 2006 Posted March 28, 2006 I had my bent and twisted D/s remade for 130, and that was including balancing. The bad thing is my rig is strictly off road, so I don't know why I had it balanced.
DirtyComanche Posted March 29, 2006 Posted March 29, 2006 Shortbed with BA-10/5 and NP231 is 43.5" Ujoint center to center. I THINK. I measured it a bloody long time ago. It's still outside if you want me to throw the tape on it... Now, if you want a 45~" driveshaft, look a 2nd gen camaro (let's say 72-81, I think) and you'll probably have a 45~" driveshaft. Not sure on what engine/trans/rear it had, but I have a feeling it was just a V6 auto. Pretty certain it had 1310 Joints too. Certain shortbed fords would also be close, based on my junkyard measurements.
Bounty Hunter Posted March 29, 2006 Posted March 29, 2006 If I remember right, will check shortly, my 4.0L/AW4 rear shaft is also 43.5". Your 4.0L/AX15 rear shaft is about the longest OEM shaft available for a 4wd, except for maybe a 2.5L/AX5 combo. IF you have a driveshaft rebuilt to work in your truck, it's cheaper to have a longer shaft shortened as it'll take an entire new tube (steel cost $$) to lengthen a stock shaft.
mjeff87 Posted March 29, 2006 Posted March 29, 2006 From memory I recall my 2.5/AX5 DS to be about that same measurement too....43.5" I can measure it tonight if you need to know. I do know that the 2WD one that was under it originally, which is sitting under my house now, is 48". HTH, Jeff
Bounty Hunter Posted March 30, 2006 Posted March 30, 2006 If you all could be so kind as post up your driveshaft length, and what drivetrain combo it's behind, I'll make a list. Then maybe we can put it in an FAQ post so somebody would know where to look for a donor. Thanks. Be sure to list year, wheelbase, engine, tranny, 2wd or 4wd. Go ahead and list the front DS length if available, in the static position.
DirtyComanche Posted March 30, 2006 Posted March 30, 2006 Rear axle matters too, the pinon length on the D44 is somewhat more than the D35, and I have no idea about the AMC 20. At least, I THINK it matters. They might have used the same shafts.
Eagle Posted March 30, 2006 Posted March 30, 2006 Rear axle matters too, the pinon length on the D44 is somewhat more than the D35, and I have no idea about the AMC 20. At least, I THINK it matters. They might have used the same shafts. No, they didn't. The Chrysler 8.25 axles in the XJs have the same length pinion as a Dana 44. Comparing an '87 XJ with AW4 and Dana 35 against a 95 XJ with AW4 and 8.25 axle, the driveshaft out of the '87 was 5/8" longer, to compensate for the shorter pinion on the dana 35.

Go ahead and list the front DS length if available, in the static position. There was one of these started over on the Yahoo site. Its in files or D-bases. You may have to look a little, it was quite awhile ago that it was done. Paging Pete: Do you remember this, or have I gone crazy again?
Pete M Posted March 30, 2006 Posted March 30, 2006 Well, not totally crazy just yet. But we were trying to figure out which MJs got the tube-in-a-tube rear driveshaft and which got the single tube style. We didn't measure anything unfortunately. Jeep on! --Pete
Bounty Hunter Posted March 31, 2006 Posted March 31, 2006 There's a whole other thread. My 2.5L 2wd '91 has that super rear shaft, it ever come on a 4wd?
mjeff87 Posted March 31, 2006 Posted March 31, 2006 Well, I just measured mine. I gotta stop hitting the pipe so much.... :oops: '87 shortbed, 2.5/AX5/231, D35 rear shaft is 47 1/2" from UJ center to UJ center (and it's the single tube one) The 2WD one I have is longer but I don't have it here to measure right now. It's the tube-in-tube type. I don't recall ever seeing a 2 pc shaft in any 4WD MJ I've come across in the 'yard, either. Maybe it a 2WD spec item only (??) Jeff
Pete M Posted March 31, 2006 Posted March 31, 2006 Nope. Long bed 4wds can have them too. I think it was Jeep's bright idea for the longer driveshafts to help reduce vibrations. Although not all longbeds seem to have the tube-in-a-tube style. Jeep on! --Pete
swirlytwirlys Posted September 15, 2012 Posted September 15, 2012 i have a long bed 4.0 4x4 ba10 trans and my rear drive shaft is about 50"
