U-Joint Torque

I was coming back from the Fly Rite Choppers last Sunday and
noticed a new vibration. I figured I broke something at
the drags in Tepmle.

Turns out it was the U-Joint I replaced only a couple
hundred miles ago. All the needle bearings were pulverized.

My question; Is there a torque spec for the U-Bolts holding the joint to the pinion? Ford 8" out of a Maverick.

Thanks

i would guess lack of grease or extreme pinion angle. i had a jacked up blazer years ago it used to eat up u-joints and they looked just like that. then i bought a needle adapter for the greese gun so i could get the right amount of greese in there and didn't have anymore problems

 

It was greased before I installed it. The last U-Joint
lasted 18,000 miles under the same pinion angle but went dry on one side.

Tyler, if you tighten them too much, then you sieze up the bearing on that side and it becomes a bushing instead of a bearing.

I think you normally only tighten up the U-bolts to 8 or 10 foot pounds. Use locktite! And get a second opinion - I'm going from foggy memory.

 

thats what i did on my blazer too. tried to put grease in them before i installed it. it didn't work for me. i don't know if thats your problem but thats what happened to me. if you can't get a grease gun into it after it's installed let me know. i'll send this needle to you and you can send it back. i think i still have it somwhere.

 

Thanks for all the feedback, and quick too.

Looks like I just over-tightned. According to the link from
Hooch It should be 14-17lb. I tightened them much more
than that.

Thanks for the offer 50merc, I can get the the zerk really easy. I had to buy one of those needles to grease the king
pin bushings.
