Before any of you fawkers get flame suit happy, Ive searched both forums for this, read nearly every topic and opinion as well as sifted through ever newbs post that had the words CTM or Longfield in his sig and still can't find a definitive answer. :shaking:

I keep blowing short side U-joints and axles in my drivers drop waggy 44. I'm running 37s and a 106:1 crawl setup. Before I keep blowing cash on replacement axles and joints Ive decided to just pony up. I'm definetly going with chromo axles.

But the price difference between CTM and Longfield u-joints is about 100 bucks. My question being since I didn't find my answer. Is one really better then the other or is it just CTM hype that drives up the price of their u-joints? I didn't see any strength test data or anything of the sort, both are rebuildable, and seem to have good warranties. If anybody has a link to some solid info, or hell if you want to post your opinion, post up.

nevermind, found the answer to my question.

Interesting read. But wouldn't you want to find a test on rotational ratings? But its a test of comparison and it looks like what im going to buy next go around.

BTW: We all had to pony up some day. Im glad I got mine done this past summer. You'll feel better on the trail as well.

That is an interesting report, but unless I am mistaken, the report does not show which size U joints were tested. Dana 60, 44, etc... Seems like an important thing to include in your findings/report in case another entity ever wanted to recreate and validate the test. Just a thought...

They're dana 44 joints, easy to tell from the pictures.

and $100.00 difference?? good to know ..Hell I can barely afford the 20.00 napa

How many miles/wheeling trips can you put on the CTM and the Longfield before needing to regrease them?

You need to regrease the Longfields every trip - the CTM's have a *thin* bushing - but that is what makes them weaker. Plus the rebuild kits for CTM's are pricey to replace the bushing and caps. I like the Longfields.

Not to mention that the test is using an old style CTM. The new design is supposedly a bit stronger than the old. FWIW, I have used D44 Superjoints in the past w/ no problems and am currently running CTMs in my rearsteer axle, Spicers in front.

I don't think you can go wrong with CTMs or Longfields. Even the Yukon SuperJoints appear to be a decent product.

Based on threads that ive read I seem to remember the owner of Longfield himself saying that under normal driving conditions you should regrease your u-joints every time you do a oil change you should be good. It would be even less if you have manual hubs, since you could just unlock them.

Greasing our ujoints every oil change is not a good idea unless you change your oil every other run. We reccommend greasing our joints every other run. If you go on a long 2 day run you should be fine. Just grease them when you get home or before your next run. Remember the grease is its cusion and life support like anything else. We do rebuild them when they get scorn or worn. We have .015 under sized caps. We turn and clean the cross down to fit them. The ujoints in the test are the D60. :)

Longfield, a bit off topic but I have an application question. Buddy wants to put a divorced case in his truck, but due to constraints he wants to use a cv so therefore he can't offset the joints to avoid galling the needles. How do you think yours would hold up?

Thanks for the grease info.

Good to know! Straight from the man himself. Question though, occasionally I use my jeep on snowy roads, and have to travel fair distances. Maybe 25 miles one way to work. Can these U-joints hold up to that?

Also have you tested your D44 u-joints? I'm guessing they should be on par with anything that CTM makes if your D60 joints did so well.
