35 to 44 swap


Recommended Posts

DON'T KNOW FOR SURE. BUT W/ YOUR JEEP ON THE GROUND MEASURE WHERE THE SLIP YOKE RIDES IN THE TAIL SHAFT HOUSING. THEN TAKE DRIVE SHAFT OFF THE PINION YOKE, AND SEE HOW MUCH ROOM YOU HAVE TO GO IN OR OUT. THE TUBES SOULD BE CLOSE TO THE SAME SIZE BETWEEN AXLES. MEASURE FROM WHERE THE TUBE MEETS THE CENTER HOUSING OUT TO THE SADDLE OF WHERE THE U-JOINT SITS. DO THAT TO BOTH HOUSINGS THAT SHOULD GIVE A ROUGH ENOUGH NUMBER TO WORK WITH. WHAT THE DIFFERENCE IN PINION SNOUT LENGTH AND DO HAVE ROOM IN THE SLIP YOKE.

I measured the difference as 5/8" but 3/4" is close enough. Yeah, the D35 driveshaft is too long. Cutting 3/4" off the end of the yoke won't do anything -- the outer portion will still slam into the tailshaft housing when the suspension compresses.

 

The good news is that its a lot easier and cheaper to have a driveshaft made shorter than it is to have a longer shaft made up.

 

Actually, the 3" lift might just be enough to make it about right. Shaggy dog story: A friend of mine had a 3" lift in his father's 95 XJ. For some reason he decided that he NEEDED to jump it up to 5", so he threw in front coil spacers and 2" blocks in the back. Took it out for a test ride and the driveshaft fell out a quarter of a mile down the road.

 

So if a 5" lift is enough to pull a driveshaft all the way out, a 3" lift ought to be enough to pull it out 3/4 of an inch. Try bolting it up and check to see how much space you have left for it to move forward. Post that, and some of us with stock vehicles can tell you how close that is to OEM.

To do a SOA takes more then just some spring perches. Up front it takes a lil bit of work and money. BUT NO YOUR DRIVESHAFT won't WORK

 

 

 

Are you talking about Oizarod115 or me cuz mine is going to stay spring under(about the driveshaft)

(temporary hijack!)

i just picked up a 44 myself...

are you sayin my stock d/shaft won't work at stock height?

(cause if so thats one more excuse to do a spring-over)

Yes, that's what I'm saying. Your stock driveshaft is 5/8" too long if you swap in a D44 without lifting.

This is interesting about the d-shaft not fitting as my dad and I just found a d44 in an 87 cherokee yesterday and we are going to pull it today. I already had the d-shaft shortend when I converted from 2wd to 4wd the shaft is still a bit long but I was hoping that after I lift it a bit more that everything would be perfect as we left the shaft about 1/2" long just for that reason. It appears we may have to shorten it again.

 

This is why I love my Comanche so much it is the never ending project fortunately my dad loves customizing cars and trucks and I guess we will just get the axle, finish the lift and spend another $46 at the shop to get the shaft shortened and balanced again.
