The longest lasting u-joint by far is the Spicer non-greasable joint. Get rid of the AAM non-greasable joints and replace them with Spicers. I'd never let a Precision joint near my truck. It doesn't matter how much grease you pump into the joint, half the time it only makes it into 2 or 3 caps, then you end up with the same problems as these trouble-prone AAM factory joints.
The extra strength of the non-greasable joint isn't an issue, except on very few extreme-use trucks, it is the superior seals that make the joint last longer than a greasable.

 

While I agree that Spicer makes good stuff, until I see a part # for these trucks with joints that don't need modified (caps ground smaller) I'll stick with the Precisions.

 

Driveline shop near me put Splicers in the rear shaft of my 03 while I waited.I pulled shaft of course.Took him all of 30 minutes tops.No issue with fit.

 

I've heard this several times but nobody has came up with a working part number. And some have said that the end of the caps needed to be ground a little so the clips would fit.

 

Not trying to hijack the thread, but since it's sort of on-topic here goes...

Lost a front drive shaft u-joint on Friday while out of town. Had a shop put 3 new Precision u-joints in (pulled the shaft myself) and now I have a vibration and I can hear the drive shaft going 'clunkity clunkity' when moving slowly. Everything *looks* right...

...what did they (or I) do??

 

they probably bent one of the ears. The only way I know of to fix it is to take the shaft to a driveshaft shop and have it balanced. (unless by looking at it you can tell which one is bent)

If your in Columbus:
Driveline 1

Thanks much! I found that my 'professionally installed' front joint had a huge amount of play leading me to believe that you're right; I think they bent one of the ears. I hit it with a c-clamp and tightened the caps up and it sounds good now. I'll see if it stays that way. Otherwise, it's off to Driveline 1.

 

I got two new ones super strength pn# 270 i think from orielly for 21$ a peice. I could tell mine were bad after 100k, lotsa slop in those babies and you should see how worn the races were also had to get a new half of that front yoke cause while beating on the caps for 10-15 min a piece I rattled the rollers out and saw that it was about worn out as wellthat was 103 with tax from the same oreilly's
