d44 with ctm joints
I am not sure here, but from what I know if one was to use ctm joints in their d44, I would think they could get away with using stock shafts. If mot stock, possibly moser shafts and have the strength necesarry to run larger than 35 inch tires without constantly grenading u-joints. Anyone have any thoughts on the subject. If you see this h8monday, I would like to know how your set up is holding up.

Re: d44 with ctm joints
To get the most strenght out of a 44 you must use alloy shafts, the stock spicer units have some inherent weaknesses. Using alloy shafts, the shafts themselves are very strong, but the 297X u-joint becomes the weak link. What you would want is alloy shafts and CTM joints. Then the axle shafts and u-joints are a pretty bulletproof assembly.

I was out Sun and a buddy was trying a really tough line and POP the 297X let go. When the u-joint failed the ear of the Warn axle shaft got bent outward and pushed the lower ball joint partially out of the knuckle. Needless to say this kind of ended the day. It would not have been an issue with the CTM joints. My buddy actually had a set, but they ended up getting loaned back to Jack and then followed a twisting trail into a white YJ. I reieved a bit of ribbing over that.

I haven't talked to Jack in a while, but he should have production going soon if he hasn't already.

Re: d44 with ctm joints
Thanks for the reply. I understand the weakness of the stock shaft, but the joint will let go first. If you were running ctm joints, would the shaft become such a limiting factor after the new ctm's would you have to upgrade your shafts also?

Re: d44 with ctm joints
You really have to run the alloys with the CTMs.
You need to have a strong yoke for the Joint, and it needs to ba able to use full circle clips. If the stock shafts and stubs are used, they will just flex under the load, and something will let go. The strength lies in the combination of strong non flexing yokes, with extremely strong, well secured Joints. Take away any one of the strong components and your right back to where you started.

Re: d44 with ctm joints
Okay, I'll ask. What is a CTM joint?

Re: d44 with ctm joints
How possible would it be to order alloy shafts for my front D44 with CTM joints?

Re: d44 with ctm joints
Go to ctm's website ( ), sorry dont know how to make it clicky. The ctm joints for the d44 run around $150 a piece. For alloy shafts, I dont know what the consensus is concerning the best but H8monday is running warn shafts with the ctm joints and I guess they are still in one piece. I think the Warn shafts run about $250 a piece($1000 a set)

Re: d44 with ctm joints
Too much money. Just go for the new forged spicer replacements for the 297x.
