"Is the pinion angle still with in spec?
Does the drive shaft have any room for the slip to do it's job?
Is the phassing of the shaft corect, if it's been split and didn't go back together just right it will cause issues."
Pinion angle should be to spec. I brought it to someone to install my axle.
That's what I am thinking may be the problem since the pinion on the new axle is an inch longer I think I it isn't giving it enough room to move.
I have no idea. I haven't messed with the shaft at all so I am assuming it is.
"Assuming you are installing them correctly and your drive angles are good, a few ideas come to mind...
Did you measure the length when you swapped the rear end? Could be the drive shaft is too long/short which will stress the u-joint (as well as other components).
Are you using a good quality replacement u-joint? If it's a greasable unit, you must make sure you pump it full of grease at install and again about every 6 months.
Does it take a lot of force to install the new u-joints? If the gudgeons are bent out of alignment, it can burn up the bearings in the u-joint caps.
Could also be the drive shaft is bent a little or somehow out of balance. Although, there is usually a noticeable vibration in this case."
I am assuming the driveshaft is too long due to the new axle. I am just using the stock shaft.
I just buy the greasable ones from NAPA.
Nope new u-joints where easily replaced.
Driveshaft is straight.

"could also be junk u-joints i had to warranty 2 of the "performance" u-joints or whatever crap brand it was from oreilly after they lasted maybe 500 miles in my jeep. swapped it out for a spicer one and not a problem since. i don't think i ever even bothered to warranty the last one."
So what I have collected from all of this is my driveshaft is a the moment too long and it could be due to the NAPA u-joints.
So now how to fix the problem... new u-joints isn't a problem. Is there any way to get a new driveshaft that is shorter but with out installing a SYE? Installing an SYE would mean adjusting the rear axle pinion angle correct?
