Also, you commented on it not being centered not being a problem, it IS out of balance if it is not centered, the reason you had a vibration when the cap came out (the joint was further from center), and even if you have a difficult time feeling it through the drivetrain and rubber mounts and bushings I PROMISE you your pinion bearings feel it and don't appreciate it. But hey, you saved 600 dollars fixing the driveshaft whats paying a shop 1100 dollars to overhaul your diff that will just need to be overhauled again because the driveshaft is STILL not balanced.

I completely agree with this But back to the Main Topic . A "Good " shop should be able to Balance this with no difficulty

I have the utmost respect for what you have done, but until a year has passed on a repair and it drives amazing you have not proven ANYTHING about replacing the ujoint. I would hope that others that may be interested in trying this realize your being ok with it failing and your trying to make it work is not an indication that joe schmoe can just go out and do this in his driveway and pull it off without a hitch. When you first got it, yes I did post a little pessimistic comment but after that I sat back and waited for the follow up posts explaining it wasn't working as anticipated... and it happened... quicker than expected.

For those wanting to do this, its dangerous and can cause other failures that cost A LOT more than a new driveshaft. You have been warned.

I also agree with this , Justin you did great , you showed it could be done and with some time and the correct tools , Rebuilding one would not be a issue . + REP . I am not a fan of the Jam nut Idea , That never seemed to have worked for me ,lol . With my luck ,one of those little buggers will come loose and fire right up through the seat and into my backside,lol

But It does show it is possible to rebuild one. If I had to do it on a trail damn right I would try it .


and 2005jgc is correct . I have broken drive shafts and seen them come apart at 60 MPH and its not pretty , This is why Drag cars and race cars are required to have a metal hoop that goes around the driveshaft in case it breaks.

I agree that it could fly apart. And by no means am i trying to perswade anyone to do what im doing. Im simply posting my findings. As far as the diff goes if it getts smoked the i will reduild it. Thats all real chaep parts. I would say that unless u do own or have accsess to a full blown shop then its proly not wise to try what i have.
Ive got another 100 miles on my second fix and so far its good. Hopefully it lasts longer than my first try.

As for the vibration i under stand that it was vibrating cuz of the cap being slid out causing it to no longer be centered. Was just saying its nice and smooth when it wasent slid out. It was even smooth when i drove a little over two hours with tape holding it together.

All in all in my opinion its not rocket sceince. No where near. 1300 For a new shaft from jeep thats f**ked up. Ill keep trying till it works or flys off on the highway.

Re: I Found a Shop That Can Replace WK U-Joints…

I had my rear diff rebuilt to the tune of $3k (!!!!!!) late in 2012. They also recommended replacing the rear driveshaft (another $1k), saying that the joints looked bad. I ended up getting a custom one built at a local shop for $800 but I returned it because it immediately vibrated even though they said they balanced it. I'm still running the factory rear driveshaft but it's always on my mind.

Re: I Found a Shop That Can Replace WK U-Joints…

We set out to find methods, shops, parts, or rebuilt units that would be cheaper than following popular belief. Either way you look at it we have many more options than just buying one for over a grand then when we started. Also we have proved it isn't impossible a few have been rebuilt so it may become a norm just like most things that were deemed impossible at one time. I call that a win.
For those like Justin who are trying this I believe the afore mentioned U joints that were epoxied had a groove around the cup about halfway up, and there was the same groove on the yoke side.

Im pickin up what your putin down.

BTW, I paid 260ish for bearings, races, seals, orings, pinion nut, and crush sleeve when I did mine then add in a couple qts of synthetic 75w140. I got parts from the dealer but was an employee that paid 10% above cost. Also if you dont have the "special tool" to properly set the backlash and carrier bearing preload done by threaded adjusters, the tool reaches down the axle tube and engages the adjusters, you can expect to be overhauling them anually.

Re: I Found a Shop That Can Replace WK U-Joints…

For less than $400 as I linked to earlier, this is the way I would go.

I have a new driveshaft that was made for the 3.7. It is available and worked just fine when installed on my jeep. No vibration at all.

Hi Mate,

Im reading up on this same issue cause i may be having this same problem soon with my mileage.
Have you trawled Pirate4x4 by any chance? i pulled this posts mid-thread which might be of interest.

"I never tacked a washer on (damn good idea) but I have tacked the caps to the actual shaft. Usually makes a d30 joint last about twice as long for me (every other run). However you do have to grind the welds to change the joint. I just carry two sets of spares and change the joints at home.

Some of my friends in the Carolinas live by this. They tack in their 60 caps. "
--------
another post
--------
"For those of you that kinda want a visual for this..take a heavy washer....big enough in diameter to cover your axle joint cap.
place it over the cap...so it is sitting centered on the yoke of the axle. tack weld on four sides...
what this does is basicly what the full circle lock rings does...it keeps the joint from popping out...even if your lock ring does pop off..it also allows the cap to move freely inside the yoke of the axle...because stock shafts will flex and break the welds if you tack the cap itself to the axle.
one thing to think about is...this is free...other than the cost of the washer.so....its not like you have much to lose by trying it."

for the Aluminium yokes, wouldnt an AL washer tacked with a TIG work just as well?
Replacement will still mean grinding out the welds, or go for a greaseable joint perhaps?

This is just a suggestion, i have no way of validating this info beyond what i read.
