Doing a U-joint repair on my current 10 bolt since the u-joint decided to take a crap on me, couldnt wait another week since the 14bff is getting regeared right now, but anyways i need the truck driving until then so this needs to get done.

The driveshaft is out and the new u-joint is in with the clips seated.

My question is on the other 2 caps that go into the rear pinion yoke that get held down by the 2 straps. Do you put the straps back on then put the other 2 c-clips in place to hold the caps in place?

I did some searching and found a post that went alittle like this...

"One the yokes with a u-bolt or trap there is a tab to prevent the cap from walking out. If the tab is missing then the yoke needs to be replaced."

Does anyone have a picture of this or can possibly elaborate more on this to make sure these u joint is placed properly so i wont have any furthur issues with it.
 
You know the lil nubs that hold the caps onto the joint that are cast into the yoke. See placement tab below

uhh yeah.. you should have them:thinking:
whered the go?

you could just tackweld the cap into place?? thats probably a bad idea...
 
I just had one of the tabs break off on my 60 and wasted the rear drive shaft, bent the fuel tank and bent a shock. I've now added those things to my inspection checklist(pre flight and post flight) to try to prevent another disaster like and from costing me another $400! I replaced with a Spicer yoke and Spice u-joint and it looks a lot better beefier than it used to... feels better too!
 
any ideas on a quick fix if that tab is in fact gone? I have a 14bff being regeared that i am going to be putting in next weekend, but i need the truck running until then.
 
Well this is not a qiuck fix cuz you gotta order them but if you look on Summit or Jegs you can buy u -jointt girdles- Maybe your local speed shop sells them. They won;t let the caps fly off. Depending on your flex you may have to grind them for clearance but they are only like $20 for two.
Do a google search for images and type in U-joint girdle

Those work really well but hardly allow any angularity at that joint.

Even if it seems like you have enough room at ride height, axle wrap and the axle dropping (like if you jump the truck or let most of the weight off of the rear) it can bind and break parts.
 
im not worried about that now, the 14 bolt is going in next week. I just need this truck driving until then and not have to worry about that u joint walking away on me.

Any quicker fixes?:D
 
How bout drilling and tapping a hole in the yoke and screwing a wide head screw in there? Let the head of the screw/bolt rest over the joint cap.
 
a co-worker of mine just suggested that as well, i just might do that. It just needs to hold for another week and that 10 bolt is in the trash for good!

Is that a 10bolt yoke? Because mine looks just like that the u-joint fits in the driveshaft just fine but not in the yoke.
 
BillyL Are you driving like that? Sound like you need one of them thar bastard joints. One size on 1 cross and another size on the other cross.

Well the 10 bolt doesnt have those little ears on the yoke and im not driving it like it was to risk having that u joint walk away again and reak havic.

So unless i can get a quick fix, im just going to have to wait put the 14bff in and then start driving.

Yeah and it's driving me nuts knowing it's like that but it is all i have to drive at the moment. :crazy: Got any part #'s on those bastard joints? :D
 
That one is 447 and I think the other is 449?????

One is for 1310 to 1350 and the other is 1330 to 1350. What year is your ride and what have you modified with regaurd to yokes and d-shafts? Lets see if we can't nail down the right one for you.
 
My 10 bolt yoke didn't have the little tabs when I got my K5. When I changed teh u-joint I just put the C-clips on those caps. I never had any problems with it the whole time I ran it.
