Alot of them sandrails on the West coast that I seen so far are running mostly 934's, very little that I seen one with a set of U-joints, I have a subscription of Sandsport magazine and don't hardly seen any so far. I am running 930's now, I have broke a couple so far due to jumping and then landing under throttle and clutching it when the tire bit too hard, I also ruined 2 axles, but they were JUNK empi ones, I went through polishing the CV's and now are running SAW axles, no more problems since then, about $700-$1000 will do for a good set of CV's and SAW axles will be the best bang for the buck and should never have to go back. In my opinion of the U-joint axles is that if they break, it could go slapping all over the place hitting your brake lines, a broken piece could come flying out and hit somebody. I heard one time that somebody had a set of U-joints on his buggy and went on climbing a hill then the axle broke cutting his brake line and he flew backwards off of the hill, I don't know how bad it was or him getting hurt, but I rather let the CV explode inside of the boot, then slowly back off of the hill then change it. OK, then why do VW run CV's on their cars and buses? I would rather leave it in stock form and run better CV and axles. I think I would rather spend $700-$1000 on the correct parts if my life depends on it, not on some junk U-joint setup. Sorry for being like this but I just want to lay down my opinion :mrgreen:

yes chad i thought i would run them once but a guy named chuck cook broke one and took out brake lines thus the nome up-chuck hill next to 3 pole

hey leave me out of this :D :D :mrgreen: i told him i didnt know if i liked the idea but i rode with three buggys mem day with them and one had a pretty bad bent arm (if he had cvs game would have been over!!!) but he rode the whole weekend with it. as for sturdy i would have to say they seem to be real tough buggiejunky beats the crap out of his and they havent broke yet. but when they do it could be messy. :oops: :cry: BUT ANYWAY THEY ARE WORKING !!!!!! :roll:

i have seen buggyjunky's buggy at wellsville (i was the one you helped out at the top of shaggy,thinks for getting me back up over the hill.lol) and he's running the side shift tranny and it sets up pretty high with those axles so i know they are running at more of angle than most cv's are,with that said evidently he has figured out a good combonation for what he is running and it is working for him.so if you are planning on running this set up maybe you should look at what he has done and go from there on what to do.extreme driveline offers a axle said to run at like 35 degrees of angle and they have all kinds of travel with the slip shaft design and there has been alot of the sand guys starting to try these becuase of the travel factor without having to run such a wide wheel base,so they may have figured something out and improved from what we have been trying.they garuantee them to never break due to stress alone so they must work,so run what works for your setup and give it hell till something gives and then you will know what to improve on from there.chad :mrgreen:

A lot of the sand guys out West running higher horsepower cars with a lot of travel have quit using the u-joint axles. I guess under load the slip shaft in the center of the axle won't slip and they are breaking the case sides on the transmission and there frames. The axles aren't breaking but everything else is. It seems the guys with lower horsepower and less travel aren't having near the problems. www.glamisdunes.com has a ton of info on the axles and most swear they will never use them again. One day they were the greatest invention ever and the next people can't stand them.

The 280 Z u joints were state of the art 30 years ago. I had a used set I bought for $40.00 on my Baja with stock travel arms and the arms notched a 1/4 " and with a healty 1835 never lost another T-1 CV. Clearancing the yoke give a litle more travel, but these days 930 CVs are the way to go, use Sway Away torsional axles will take some of the load off the transaxle. Don't waste your money on the chinese copies as they have a tendency to break the splines. You break a cv the axle spins inside of it. With the u joint broken it reaches out and touches something with extreme predjudice.

yea it was burnt pretty bad,nothing in the drive train was hurt,the motor had bought 10,000 miles on it,it had a 4 barrel on it,it had to be an early 80s about 35ft long,it had big 6 lug wheels on it with a floater axle in front of the pulling wheels

Sorry I hijack this thread but they always use really neat stuff in motorhome chassis. Im always interested in the suspesions. That one is definatly one I've never seen before. Thanks for post ing the pics. I would bolt those u-joint axles right in my buggy if they are forsale, are they?

No, I have been running type 2 cvs with Deans special order arms. They have held up so well that I broke the spiders out of the diff. Dean has a special setting with the arms that the cvs dont break as much. So I figured I would stick with them. Plus the u-joint shafts are real exspensive!
