Title: 1350 U joints
Post by: 7212Mopar on November 06, 2018, 09:46:25 AM
My new 1350 driveshaft was delivered yesterday. It came with everything except the two outside spring clips for the U joint cups to the pinion yoke. I do have the U bolt straps from Dr. Diff.

Have anyone used U joint girdles? Are the girdles intended to eliminate the need for the spring clips? It looks like the girdles cover part of the U joint so the cup cannot come out. I am thinking just getting the girdles since I don't have the spring clips.

Not sure on your questions but just thought I throw out there to check clearances to the pinion snubber. In had to modify some things on mine (Dana) so it didn't hit. Girdles might require even more room?

Hi Brad:

Pictures of the girdles and the spring clips. I do not have the two clips for final attachment to the yoke so want to know if the girdles can substitute the spring clips and U bolt straps.

I would say yes when using the girdles you don't use the 2 clips. But I'm no expert on the subject

Is there some reason you can't call the driveshaft manufacturer and ask for the two missing clips? Sounds a hell of a lot easier than the other way. Just my  :alan2cents:

New York vs Reno. Summit will be faster. Or go to local Napa Auto. Mainly want to minimize chance of things coming apart on me again.

What are the clips going to grip?  Never seen a outside clip used at the differential yoke......  Either inside clips like Mopar used or the yoke has retainer tabs.... Look at these two yokes, how is the cap gonna escape?

I see. As you can tell I have not deal with non Mopar U joints using the outside clips. The Dr. Diff forged rear pinion yoke I have looks slightly different from your pictures. But I do see it also has a shoulder which forms half a circle that is smaller diameter than the U joint cup. The reason I thought the clips are used is because the groove behind shoulder (inboard side). Also watching youtube videos, one author talks about using different thickness of clips to center the U joint and to set U joint end play to factory spec. He was working on a Toyota shaft and mentioned Ford and Mopar don't have factory publish tolerance. Just want to do this right so that I don't mess this up again. The girdles I ordered will form the second half of the circle and for sure the cup is not going to fly away.

Hmm: I've never used a 1350 yoke like that. With the girdle I would put the u-joint in relatively dry and make sure there is no play to be taken up.

I emailed Cass and he confirmed no clips needed for attaching u joint to the 1350 pinion yoke.

Driveshaft and u joint girdle installed in 15 minutes. Everything lined up and no play. No chance of using a torque wrench to tighten the girdle bolts to 45 ft-lbs per instruction as there is no room for it. I just used box wrenches and tighten by hand.

Nice! How does the pinion snubber fit?

The whole assembly clears the snubber. The tight spot is the rubber piece sticking out at the bottom of the bracket with about 3/8 clearance.
