I have a couple of questions regarding the detroit 7260 u-joint style. I have a 1991 dodge power ram 150 and my rear driveshaft has the detroit 7260 u-joints with the inside snap ring. I have been having problems with the u-joint being loose in the caps under the straps. And I have figured out what's goin on, I don't know if anyone else has noticed this or not, so that's why I'm asking. But I have noticed it on 3 different u-joints the precision 315 thier standard u-joint in the 7260 style and the precision 246 the super strength series in the 7260 style u-joint and the neapco 1-6300 u-joint. What I have noticed is the notches in the caps where the snap rings go are too big, ether that or the snap rings are too small, and because of that when I install a brand new u-joint wether it be a precision 315 or precision 246 or neapco 1-6300 there is movement with the straps being on tight. Has anyone else noticed this issue? My second question is can I tack weld the snap rings onto the caps to eliminate any movement? I have not noticed this problem with the spicer 5-1306-1 but I can only order them online and I have to wait a few days for it to arrive. I noticed I can move the snap rings side to side while they are on the caps, so I was just thinking if I put a little tack weld on the inside of the cap it wouldn't be able to move anymore and therefore the u-joint wouldn't be moving inside the yoke anymore ether. What are your thoughts?

I would not weld anything and I would get the Spicer U joints.
They say there are no such thing as a stupid question. They say there is always the exception that proves the rule. Don't be the exception.

Nope I just bought all brand new straps and bolts from Napa, they are the 7260 straps and bolts, I can clearly see what the issue is, the notch on the caps are ether too big or the snap rings are too small, I can move the snap rings side to side, so obviously that means they can move side to side when bolted up to the yoke. I waisted 25 dollars on that precision super strength 246 u-joint, super strength lol loose right out of the box but it's a super tuff u-joint, what a joke.

It sounds like, to me, that the yoke is damaged I have a new , 2 or 3 runs on it in my Duster that runs low 10 in the 1/4 mile, Spicer 7260 pinion yoke that ended up spreading out far enough for the cup on one side slide out with the retainer on it I ended buying a forged steel Yukon pinion yoke for it My message is when parts don't fit right there is usually a reason for that problem The hard part can be finding what is wrong with which part Find it and fix it before it hurts you I wouldn't be suprised if it is the yoke or the straps being mispackaged Do the new Ujoints cups snap into the pinion yoke and stay put? If so it has to be the straps If not then it is possibly the pinion yoke The straps are there to limit front to rear movement of the cups, not side to side

I've never had good luck with Detroit. Spicer for me all the way.

Cheaper U-joints tend to be not as precise as the quality units. For example when I replace U-Joints on Yota trucks the factory cups have to be pressed into the yokes where as the parts store cups just tap into the yokes with a small hammer I only use Neapco joints or Lakewood which is a Neapco in a red and black box.

Cab, my I am glad to wade through your emoticon forest because you usually have good information based on what seems to be a lot of real world experience. Happy New Year! R.
