drag radials=broke U-joints???
I went to the drag strip the other night on a pair of my buddys drag radials, and broke three U-joint, the side yoke in the rearend, and beat up one of the half shafts. After I fixed all of that I found out that I also had a bad wheel bearing, real bad. I really need a new set of rear tires, and my question is If I run a dragradial will this happen again, or did the bad wheel bearing cause a lot of it??? I really hate to spend 600 dollars on tires when I can spend 300 and hook up better. Thanks :confused:

I replaced all of my U-Joints when I did the gears (new spicers) and run drag radials exclusively. No problems yet (knock-on-wood). :) I would replace your bad bearing and all of the U-Joints. You shouldn't have any problems...

DRs will allow you to realy stress the chassis and drive train.
If you have and A4 you can reduce the shock by preloading the chassis to near the stall of the TC before launch.
What kind of 60' times did you pull before the mishap?

Sounds like it all needed to be replaced anyway. The only time I have broken u-joints was when I had Brute Force installed and was launching on ET streets. The Brute Force had less than 50 miles on them too.
I would say that the bad wheel bearing assisted in getting the u-joints out of alignment and in a bind causing them to break. 3 at once is a major feat unless there is something else that caused it.
Put in new Spicer u-joints for a better chance at keeping it together. They have held up in mine with a 4500rpm clutch dump and brand new spec stage 3 clutch. Granted, the hardened outer spindle snapped in two, but hey, the u-joints held together. I run the cold forged Spicers tom Tom's Differential out of California.

I replaced my U-joints last year. should they already be bad??? The local parts store told me that the U-joints that I just put in were as good as spicer, Maybe. Does anyone know how to make a halfshaft loop, or were to buy one??? Thanks

So what brand were they? Some have said the Brute Force were the best thing going, lol.
Just look at what Denny's Driveshafts put on their Nitrous ready driveshafts..Spicer :yesnod:.

is it possible that the bad wheel bearing had somthing to do with the u-joints breaking?? Should I buy the drag radial or not buy them???
