School me on u-joints

[xjoe]

Decided on superior alloys for my 44, which joints to run? Really like bobby Longs new u-joints. I know there are a few more out there, OX, CTM & Randys. Cost is always a consideration, but warranty and customer service is more important to me. Thanks, xjoe

I asked the same question on another board a few weeks ago. Most people said just stick with the Spicers at $60 each. The OX and CTM are just way too expensive to even think about.

[xjoe]

Anyone else...

[JonsYJjeep]

buy the CTM's and stop asking :flipoff2:

[xjoe]

buy the CTM's and stop asking :flipoff2:Oh allright CTM's it is, and superior alloys :flipoff2: So when you gonna stop givin me shit about my xj 44 and get rid of that d30 of yours? When are you gonna do a spring over and put some 35's on your heap... :flipoff2:

Call Jack , run ctms , your superiors will thank you later...... :smokin:

$60 Spicers? me thinks you are talking about D60 joints...

[lincontaco]

ctm's, i dont think superior will warrenty their shafts if one is taken out by a u-joint failure, even though ive watched my buddy rip about a dozon spicer 760's out of his and it never hurt the ears.

[Janster]

Run $20 Spicer joints (760's for example) and let them be the weakest link.....

If you find you're breaking them too often, then get some beefier u-joints (CTM's, etc) and something else will now become the weak link....

...and when you discover what that something else is...then go with a D60. :D

Set your steering stops correctly and run 760 joints. They will hold up fine as long as you keep the steering angle within specs. By the way, the Spicer spec is a maximum angle of 40 degrees. CTM is 50 degrees.

That does not sound right

[rtaylor]

That does not sound right

That's straight from the Spicer cut sheet. The CTM info is from the developer of the CTM joint. During a phone conversation with him (I can't recall his name), he said that he is working to increase the number to 55 degrees.

I dug the info out because I kept breaking u-joints, which resulted in destroyed axles. After breaking three joints, I did the research and have not broke anything since adjusting the stops.

My steering angle measured 66 degrees before I adjusted the stops (I had to replace the stops with longer bolts). It doesn't turn as sharp now, but I can accept that, if it saves those $480 axles...

don't try and buy anything from superior, they've been giving me the run around for the past month about gears. definatley not the company they used to be.

I personally like to use good u joints in the axels and cheap ones in the front driveline at the front diff so if somethin is gunna give it will be the cheap and easy one to fix on the trail.

Very good point. I run 1310 stock u-joints in my driveshafts with my built axles hp44/9". They are much easier to change out then axle u-joints. Also I can use stock front driveshafts front and rear so that cuts down on the cost. Cheaper breaking those driveshafts than alloy axle shafts or OEM axle shafts.

I run OX u-joints and I like them and their customer service. I tracked down their phone# and website. On only 1 run on the Rubicon I was missing both screw center caps on my drive side u-joint and 1 of the 2 locking races and 1 screw cap on the passenger side. The parts are $5 and $7/ea so not too bad. I'm going to make sure to clean the u-joints up and use some lock tite this time on the screw center caps. As for the official testing done by OX:
Spicer 297 u-joint: 4,500 lbs before it broke
Spicer 760 u-joint: 5,400 lbs before it broke
OX u-joint dana 30/44 10 bolt: 21,000 lbs and they couldn't break it, I think they finally broke it at 35,000 lbs from what Chip the OX parts guy told me.

If you're spending the dough on a set of Superior shafts, it would be foolish in my opinion to run a stock u-joint, which when it goes out, has a good chance of taking the ears of the shaft out as well. I'm running a set of Dutchman alloys in my 44, and went with Bobby's 1st generation ujoints, and I don't regret spending the $$ at all. His new joints should prove to be even better, as the first was simply a glorified 760, but works great.

[roundeye]

We chose to carry CTM joints because of their past performance.
They're not up on the site yet but if you give us a call, we'll give you a great deal.
Unfortunatly, I don't carry other ujoints at this time. The Alloy shafts are recommended to couple with CTM's. I believe superior says the same thing.

I retract my statement about running the Spicer 760s. On my first trip with my new axle/joint combo, I grenaded the spicer joint which took out my new Superior axles with it. BUY the CTM joints and be done with it:)

By the way, Superior is replacing the axles under warranty with no hassles.

I'm calling BS.

my MOG's only turn to 50 deg, and thats if you clearance the CV's No way in hell a 44 turns anywhere close to that.

i think max angle on a 44 is in the area of 35 degrees.

X2 - 66 degrees isn't anywhere near possible. :flipoff2:

no shit.

rtaylor i think you are measureing the wrong side of the angle, thus the misinformation.

me thinks you had somewhere in the area of 24 degrees, not 66.

My factory service manual says 40* steering axle which is a d-44.

MAXIMUM maybee

correct me if im wrong but wouldnt it be physically IMPOSSIBLE to get more than 45*

:confused:

:confused:

As far as I know, it is physically impossible for any single u-joint in any mechanical assembly to exceed 45 degrees operating angle. In order to exceed that limit, you must use more than one joint.
