They weren't the cheapest ones, and frankly they were only going to be in the truck for a max of three days. In fact i even told my brother that i hated NAPA joints because they break (three previous cars have had NAPA brand due to immediate need, and they have all broke), but they have all lasted at least a month. At this point i am really just trying to make sure that nothing else could of happened, and that this happened due to bad parts. I am curious though, what brand would you get if you needed some u-joints now, and could not get spicers?
Thanks!!!!!!
Thanks!!!!!!

if you get a ujoints with out the zirk fitting they tend to be stronger. if the hubs were locked and he was driving faster then 55 that could have been the cause coupled with the drivline not be balanced to the slip joint not being greased up if that makes sense

if the front drive shaft isnt balanced or say the slip joint that allows in/out travel of the drive shaft is worn out as it spins up faster it will get out of round easier causing stress on ujoints. i know my front drive line is worn out slip shaft or what ever its called.

well lets see, front hubs, locked.. dry pavement.... then a big BANG...
Hubs should always be unlocked when not in use. regardless of transfer case placement,
you had it in 2wd, but the hubs were locked , which means the whole assembly was turning all the way to the transfer case, and free wheeled.
the front driveshafts and parts are not designed to do highway speeds. SO, it went bang for a reason.
The only difference was you didn't have the 4wd engaged to turn the front with the motor. but the whole assembly still turned. Always unlock, and check them to be sure.
napa joints are fine. you abused it and the whole driveline.
th ujoint did as it was supposed to do, it let go, as designed to keep from breaking those more expensive parts.
have you priced a 44 chunk lately? labor alone would cost 350...
Napa ujoints work fine, it is the user.

When I lived in Canada. (for ten years) I would lock the hubs every fall and not unlock them till spring. (I would unlock them on a 200 mile trip) but I drove them at 70 MPH many times and never had an issue with the u-joints. The only part that is not desined to run at hyway is the transfer case. That chain really gets humming. But even that will do it ocasionally.

On top of all that, I wouldn't expect a big bang from the truck when it has an open front differential and the transfer case in 2 Hi. The u-joints are pretty much the same as the rear driveline, so why couldn't they take a freeway spin? Since the truck in question belongs to my brother, I personally took a look at the carnage, and the U-joint was a piece of garbage. It literally fell apart, no signs of tearing the metal (not counting all the stuff around it that got beat to a pulp) just a near clean break, which is an indication of a brittle fracture - where a piece of metal just snaps well below its rated load.
