Anyone ever rebuild a Double Cardan Joint (CV)?

I'm 90% sure the little ball joint in my double cardan is toast. Anyone ever replace one? Napa aparently sells replacments.

I'd rather fix a driveshaft I have than buy a new one.

Go find a used one in good shape for cheap. pain in the ass without the right knowlege/tools (im not slashen your ability) to take it appart. and theres no point in pulling it appart unless you replace the U joints aswell, murphys law they'll have slop 3 months down the road if ya don't. For the money you'll have into it, Ive picked up good ones for a case of [31]. if ya want it rebuilt, its worth the $100 to have a day to yourself and let somone else piss around with it. :D

I agree, i chopped mine up and run a single u- joint to avoid the hassle, but i was only able to do this because ive got a square tubing drive shaft. If you find a used one check it over real careful.

I don't really want to climb under every Toyota I find at the junkyard (if I can find one:() looking for a decent shaft. I doubt I'll even find a decent one. I have 3 of driveshafts, all of them do the same thing.

But, for 100 bucks and a Saturday, I can have a basically new driveshaft.

I think the U-joints themselves are okay, it's just the double cardan that needs work.

@ wade and cleatus
You get any vibs with the square shaft? Even with the single U-Joints?

its fairly easy to do ...

cant remember the part #'s off of the top of my head , but I always use "Precision joints and ball kit" ... I have some pics I could email you if ya want .

hard part is getting the old "ball race" out .

Where did you buy them from?

Napa is showing 2 sizes, .467 ID and .513 ID. I guess I'll have to pull it apart to get the size first.

How did you pull the old one out?

BTW, how goes the hotrod?

lordco has em ...

ujoints are # sorry .. dont remember (i can get it if ya need)
center kit is # 513 or 514

I ended up welding a bolt ..into the space where the shaft goes (you'll see when ya pull it apart ) and "yankin' " it out that way .



"hot rod" is goin' slow .

do are you getting vibrations? if you are it is the driveshaft binding, and that will happen on all of them unless you run a shortened driveshaft froma long box toyota, that is what i am running now and with dual transfer cases i dont get the slightest vibration, that cv is stupid anyways, it puts all of the angle on the pinion u-foint, and doesnt give you a better angle at all.

Thanks. I'll be allright with the u-joints. I just wasnt sure on the ball.

The driveshaft I have on now vibrates pretty bad, but it's cause theres to much slop in the double cardan. The Joints are bottoming out.

The double cardan does serve a purpose, but if you're running dual transfer cases it isn't as important. Heck, if this doesnt work out, I can always shorten the extra rear shaft I have. Shouldn't be to hard.

So how tight is that ball suposed to be? The ball practically fell out of mine...[16]

As for the race, that thing is stuck. Where did you weld the bolt too?

I noticed that the dust shield or whatever is pretty chewed up, guess I know where the sound was coming from.

the cardian joint sucks. just shorten a rear shaft, or if ya want a stock stile shaft i'm pretty sure i've got a good one. 83 short box length, if your interested i can measure. i think it even has new u-joints on it

How much slip does a rear shaft have? I'm considering throwing the extra rear shaft I have on the chop saw to shorten it up. Doesn't the double cardan have a different bolt pattern?

But I'd still rather rebuild the one I have. I have it torn down enough to pull the ball race out.

I welded in the bolt .. to get the ball out .. yours fell out = TOAST

race is a bit more of a problem .. I used a hammer and chistle to get the old one out .. if your not takin' out the u-joints .. little bit more of a problem .

I have also scuffed up the race , and welded a bolt to it , and used a puller "type" hammer to yank it out .

after your done ... you'll be happy .

I have done a bunch of them now , including my own , and never had a problem with longjevity ... Provided the splines are in good shape , its a quality repair if done right .

Ya, that race is in there good. But I'm sooo close.

Does the race look like this when it comes out?

Yeah, i get some vibes but i only use 4x in low speed situations, although i have had it up to 70 on the beach without any death rattle. I think i get more vibes from my pooched rear shaft[27]

You get any vibs with just the hubs locked? I'm asking cause this is my winter transportation, gotta be able to drive with them locked.

I get no vibes ... just crappy fuel economy when hubs are in .

With the hubs locked the vibes are worse and the square tubing makes a lot of racket. Its not really a good set up for your application.

So I picked up a new ball from Lordco today. I couldn't belive they had one in stock. Came to 85 bucks after 30% discount:eek: .

For my 83 it was:
Precision 613

they are easy to re-build, just rember to replace the seal where the pin rides between the two u-joints

Amiel Voth
12-08-2006, 04:48 PM
Well,I got it mostly together.:D
I have to scrounge around for some c-clips tomorrow.

I had it almost together when I realized I forgot the seal.[27]

For anyone interested, the old ball race looks like it is brass. I chiseled through it and it came off easy. I'm not surprised it wore out. The new one is steel, should last a while.

Thanks.

If anyone is curious, I re-used the old Ujoints as there was no slop in them.
