Re: Troubles with Double Cardan Joint
The part you are trying to name is a centering yoke. I replaced one on my 89
XJ before. What a PITA. Be exeptionally careful with the little red cap on
the back of the new one. I'd probably just go pull a used shaft from a
junkyard XJ, slam 3 $10 U-joints and a $60 centering yoke in it and be done
with it. Keep the offending unit as a trail spare.

I actually bought the new center yoke and two U-Joints (I need three joints,
but one of them has the the yoke holes so mangled that I can't get that
joint out.) When I reinstalled the shaft, I noticed that the various yokes
very nearly strike one another at normal ride-height, and when the axle
drops, then a strike is assured. I have to look at my current Trail Spare
(and get it trail worthy) and see if there is an machining difference in the
old parts and the new ones that causes the strike opportunities. My old
drive shaft did not have the problems with strikes, but the splines have
worn out so I bought a new drive shaft a few years ago, and now the worn
splines are the Trail Spare.
I could go pull a used shaft from an XJ, but I think it would be about a
foot too long to fit my CJ5.

Re: Troubles with Double Cardan Joint
Sorry, Jeff, I thought you had an XJ. Can you get an angle finder and
measure your pinion angle? I can see the double cardon flexing too far if
your angle was *really* bad but I think it would be easy to visually
confirm. Is the pinion pointed straight back or is it pointed at the output
yoke of the t-case? Can you get some pictures of the pinion, CV joint, ect?

measure your pinion angle? I can see the double cardon flexing too far if
your angle was *really* bad but I think it would be easy to visually
confirm. Is the pinion pointed straight back or is it pointed at the output
yoke of the t-case? Can you get some pictures of the pinion, CV joint, ect?

Re: Troubles with Double Cardan Joint
To be honest, I don't know what the angle is.
I bought my Jeep as it sits, then broke a spring so I replaced them all with
the same amount of lift. The driveshaft had worn splines, so I bought a new
one. The new one is the one that keeps eating the center joint. The original
shaft never gave me a moment of trouble, but it is unable to hold grease
anymore, and I was worried that the splines would let go at a very
unpleasant moment, or let go and turn a wonderfull moment into one of the
most unpleasant imaginable.
In any case, I think the body of the H-yoke and the various other yokes are
somehow different shapes by an 1/8 inch or so, and this 1/8 inch is vital.
