Jeepers!
driveshaft upgrades. 258 T176 model 300 to 20 & 30 axles w/lockers. What
do I need in the way of upgraded driveshafts?

Whut wus rool nummer teyun all bout anyhow?
Back to my professional voice now, not the one I was born with ;^)
If it's still stock height, I have had good luck with the OEM units, but
whatever you do, get rid of the strap style Ujoint yokes and put some ubolt
style ones on. That is usually the weakest point of the stock driveshafts
from later years. My rear driveshaft is so short and at such a steep angle
that I had to have a CV style made by Tom to keep the back wheels turning.
The OEM was fine until the T18a and 4" lift.
The most important part of a good driveshaft in my humble opinion is to use
top quality Ujoints. The only ones I have found to hold up long term are
genuine Spicer or Neapco. There may be other good brands out there, but
these two appear to have hardened cross shafts and caps, and hold up many
times longer. The chain parts store's house brands just don't seem to cut
it.
Hope this helps,

and a double-Cardin joint? I can't find any difference myself but the
terms aren't always used interchangably in some publications.

So whats the advantage of a CV, if any?

transfer case to help get a better driveshaft angle without
vibrations. With regular U-joints, the rear pinion has to be
parallel to the t-case output, or else you will get vibes. With
the CV, the pinion should be in line with the driveshaft. (I try
to set the angle down about 1 or 2 degrees, planning on it
becoming straight when there is power to the axle. Small point,
but its worth a try.)
As for driveshafts, I had a Grand Wagoneer front CV driveshaft
cut down for a customer, and installed it in the rear of his
lifted CJ-7. He had vibrations when he came in with the spring
lift and angled shims installed that came with it, and the
original driveshaft. We got rid of the shims, angled the pinion
in line with the new CV driveshaft, and no more vibrations. The
driveshaft has pretty thick tubing, so it should be pretty
strong. Cost: $35 for shortening the shaft. We had to use an
early-80's downsized Cherokee front driveshaft transfer case
yoke to mate the Wagoneer CV joint to the Dana 300. Bolted right
on and everything worked slick.

Sounds like good information. So, do you think a CV is a necessary upgrade
on a CJ w/ a 4.5" lift?

Cardin's. However, there are other CV's (like you'd find on an independent
suspension) that are not. Those are a ball type CV.

a 4 or 4 1/2" lift. I'd say that for the cost, using a GW
driveshaft would be a good upgrade. Even if you bought a used
driveshaft and put in new U-joints, you should come out of it for
under, or near, $100. It should help the U-joints last longer
also, since they are at less of an angle. Depending on the lift
and transmission you are running, you might even get away with
using the driveshaft at stock length. We only had to take out
about 2".

What if I'm lazy and want to walk into my local driveshaft shop. What do i
tell them to make me? IOW what diamater? Also how do I determine length?
1983 CJ-7
Proposed Fuel Injection on rebuilt 258
T-176 4-speed
dana 300 T.C.
Superlift 4" lift
Model 30 Axle front new Warn hubs and soft locker
Model 20 Axle rear new Warn manual hubs, float kit, disc brake kit, detroit
locker
Right now the vehicle is a painted frame with the painted lift and painted
axles bolted on, sitting on jack stands in my shop. I have not decided on
the transmission yet (NV4500) $$$ But at this point it's time to plan the
rest of the drivetrain & I had heard that a CV upgrade was beneficial.
