Busted Ujoints

Well I was driving to autozone to get my core charge back on my motorcraft 2100. So I am being tailgated, so I shift up into 4th, and then i hear a noise for about 3 seconds that gets progressivly louder, than LOUD smacking. I immediatly swerve off onto a side street. Toasted the ujoint on the rear output shaft of my transfer case. So I pull the driveshaft, and limp home in 4wheel drive. Well one of the bolts that holds the bracket that holds the ujoint onto the rear yoke got sheared off and is still in the yoke... Do i need a new rear yoke, or what do I do?
What size Ujoints do I need for both my rear and front driveshafts? ( might as well replace them all at the same time )

Re: Busted Ujoints

I had something similar happen two years ago. I drilled a small hole in the sheared off bolt and used a screw extractor to remove the rest of the bolt. Since then though I have changed to u-bolt yokes.

Re: Busted Ujoints

Will is right.
Try to get a U bolt style yoke and a new yoke nut, install them and then this most likely won't happen again.
Until then sure, try to drill out the old snapped strap bolt and replace it.
A reverse rotation bolt extractor bit can be a big help here ... if you can get a hold of one ... [img]/wwwthreads_images/icons/smile.gif[/img]

Re: Busted Ujoints

It should come out easy. The size is 1310 for your Scrambler.

Re: Busted Ujoints

Last weekend I rung off a rocker arm bolt on my junkyard 304. My buddy snatched up a die grinder (whilst I was still cussin'!) with a cutoff wheel and cut a groove in the bolt shard(it was flush). Then used a flat bit screwdriver to extract it. Boy was I relieved!!

Re: Busted Ujoints

I would get the u-bolt yolks, I think you can dill out your current yolks to accept bolts also I would buy the u-joints and then just take it to a place w/ a press to press out the old joints and press in the new ones. I know my tj's u-joints didn't want to come out in the drive way.

Re: Busted Ujoints

the u-bolt style yokes are the same on a dana44 diff as the dana 300 outputs. you can steal them from a j/yard. just a thought.

Re: Busted Ujoints

As much as I appreciate the existence of 4 wheel drive hardware and Quadratec and places of that caliber I do not appreciate getting screwed on shipping .they charge you double what it costs to ship stuff if you send it back you have paid shipping three times plus a restocking charge.
So that being said it is time to go back to the twentieth century and pick up the PhoneBook, remember those? and find a local driveline place and save yourself some cash ...and boost the local economy .I saved about $ 8.00 on the cost of the yoke and didn't have to pay shipping.If you look in the 4 wheel drive hardware catalog at the yoke that is the Dana part number and you can use it to call around for prices ,that part # has also been posted on this board a few times.Unfortunately I found this out too late to really benifit from it as I had replaced two already but the third one on the front axel is the same .the rear AMC 20 already had the U bolt type,thank the powers that be .

Re: Busted Ujoints

I agree with Ray. I love looking through the quadratec and 4WD Hardware catalogs but I can find most parts cheaper locally. At least Summit and Jegs don't charge shipping.
