Issues with D-44 swap

So I have a few issues. I think the only way to fix them is well more money.

1- when I hit a bump with the back tires there is a huge bang and it is a force full one. I jumped under it this morning and kinda saw the issue of the driveshaft having no more room to move on the slip yoke (bottoming out) any way to fix this besides SYE?

I have to do SYE one of these days but I now have to buy new rims since my wheel adapters will not fit over the warn locking hubs for the front. When will it ever end

That is the way it goes when you start modifying any vehicle.

You have to pay to play.

Thing that pissed me off the most was with the wheel adapters. Was told they would work. I could of bought new rims for the truck for another 50 bucks then the adapters.

Yeah, that hurts. Just think how much nicer the D44 will be though...

I lucked out with mine, I didn't know enough to look for the D44 when I was buying my Jeep but got lucky and ended up buying one with a D44 and 3.73s.

Sell the adapters and get rims.

That is what I was thinking well probably the fronts I can return since they have not been mounted. The rears well have 50 miles on them. The dana 44's for the front and rear I got were 5 on 5.5. I have 5.13 gears makes a huge difference gettin the rig going.

Would you be able to fix this with adjustable controll arms? when you do go with a sye you will need them anyway ( at least the uppers)

I converted from a D35 to D44 but didn't have that problem because my TJ had nearly 4" of lift at the time. The D44's pinion shaft is not only about a half-inch longer, the ring gear's larger diameter positions the pinion shaft closer yet towards the the transfer case. So without insufficient suspension lift height to create the extra space needed to hold the now too long driveshaft, you'll have the problem you're having.

You absolutely (!!!) cannot drive it like that or you stand an excellent chance of destroying the transfer case or seriously damaging the new Dana 44. Either have the rear driveshaft shortened or install a SYE kit and CV driveshaft. Good luck with it.

I did the same swap. I already had a SYE and the axle bolted right up with no issues.

thanks for helping jerry, we put this rear in at my house, and he has a 4" lift. i haven't looked close enough again, is it possible the angle is too steep to allow it to slip? we did have to take the t case drop out, cuz the shaft was too long, but after that josh put the shaft in and i didn't look again.

since he doesn't wanna spend more money yet, what about a shaft out of a 6 cyl auto tj, would that be shorter, or same?

Dave, I just talked to Josh and I think you nailed the problem right on the head. He said that his lowers are aftermarket and about an inch longer, but the uppers are still stock. I think the pinion angle is low enough to where it won't let the shaft sit properly.

That the DS angle is binding the slip joint is a good theory I hadn't thought of.

It's been long enough that I don't recall 100% but I believe my old AX-15 was shorter than the automatic tranny I swapped in so that should make a DS from an automatic shorter.

Good luck with it Dave.

Thanks Jerry- Yea I am trying to figure it out. Just got home and looked again the driveshaft is too long. It is flush up against the transfer case with the slip yoke. I am at 4in of lift too. I think my only option is to get adjustable uppers and SYE. Then I still have to get new wheels too which just adds frosting to the top of my S*&t list.

That is REALLY strange that your DS is too long with your 4" lift. I installed my D44 with the same DS with only a 3.75" lift without problem, as I recall.

Oh wait a minute... a steep lift like 4" shortens the wheelbase, I'm betting that's the issue since you're apparently still running stock control arms. When I installed my D44, I lengthened my control arms to move the axle back so it was again centered in the wheel well. Could this be what is going on with yours?

I have longer lowers that came with my lift (bout an inch to a inch and a half)- I am feeling that I am going to need to get adjustable uppers and lowers with a SYE.

thanks jerry and jack. its possible its too long, i just have a hard time beleiving a stock d shaft is gonna be too long w/ a 4" lift. i can't believe the d44 makes that much difference. i know its longer, and pinion is longer like jerry said, but to be that much too long?

i'm hoping the angle is too steep to allow the shaft to slip. if it is to long, is an auto 6 cyl driveline longer? so a stock shaft from one would be shorter right? in case we need another bandaid.

I am figuring I am going to pull the driveshaft off drive it in 4H and just tug my heep along when I have too.

Dave pick up your phone.

I'm betting Dave that is was fairly tight with the old 35 in there too. Just made it worse with the longer snout of the 44.

Like I said earlier Josh, easy fixes would be to look for an auto shaft or take yours out and cut it down an inch or so.

Measure you drive shaft from center to center of the joint.Is your Jeep standard or auto?If auto it should measure around 13.5" or longer then you can pick up a stock rear shaft on Ebay for around $80 that measure 11"s from a standard shift Jeep.If you already have the 11" shaft then SYE is the only way to go.

For that price I might as well put in adjustable uppers that will make the drive angle better along with move the pinion angle back up for the truck to like me better.

80 bucks?Adjustable uppers for that???Hummm doubt it but even then if it is hitting that hard right now, then pushing back the top is probably not going to stop the chance of it still bottoming out at full flex or at the point were the suspension is compressed.I had a Mustang once that i should have had the shaft shortened in after a motor swap and didn't do it right away.At every pothole or large bump it would bang something fierce.Needless to say after about 5 runs on it ,it busted the tail shaft housing on the trans and the rear end housing at the same time.But it is what ever floats your boat.

^ yea I know what your saying. I avoid bumps like the plague right now. The adjustables are 160. So I need them anyway that is why I was saying just spend the money there and not on a shorter shaft just yet. I need a SYE BAD too. So just little bandaid fixes are not what I am trying to do.
