yokes 4cyl vs V6

So I noticed the driveshaft and axle yokes are bigger or wider or something on this 55 4 cyl CJ than on any V6 powered CJ I've ever seen. I'm wondering which is stronger or better. Should I save the yokes off this 55 and put them on my 71 V6 JEEP ? I may doing some serious mods this winter and so that would be a good time to incorporate better, stronger yokes if it's worth it.

 

yes it is worth it, the larger U-joints are better. They changed 62,63 or 64 cause I got a '60 with the larger and a '65 with the smaller. Both F heads

Wonder if you could make a switcherooo at the slip joint/splines and actually run part of one shaft and part of the other together. Sounds kinda butch I guess. There I go thinking again.
Guess I'll have to change the yokes on both axles and the T/case. OOOPHHHhhh. Wonder if all that will just slip right on '68 t/case along with twin sticks from the 55. Asking a lot ain't I. Nothin's that simple.

 

Wheelie I've changed yokes with no probs. Just make sure that the spline count is the same, and maybe while you're at it replace the seals.

 

now the next question why is the 4 banger bigger than the v-6? my theory is oil pan clearance...

Prolly because they were designed before manufactorers started to design for "just good enough" Maybe the older ones were "overbuilt" for a reason. That's why we've been able to put bigger engines and tires on 'em for years.

 

Part of this may be the type of steel and how there made. Just because it is larger doesn't mean its stronger, one could be cast iron and one could be forged iron or forged steel and 95% of the people looking at them wouldn't know. Look at connecting rods in a racing motor, the aluminum ones are about 25% bigger but they are not stronger just lighter, forged steel rods are stronger than cast iron or forged iron rods and they are smaller by about 10-15%.

 

good theory too.. I was looking one day at replacing my yoke wiyh a larger one from a willys wagon and It looks like with the stock suspension and a good bump that the larger one would take a bite out of the V-6 oil pan.....

cccc

What to do, what to do. I figured they might be stronger cause of the torque induced by 5.38's. Geez, now I dunno. I'll probably swap em. If nothin else, it'll make conversation with someone oneday.

 

switch yokes on the axles.

 

Leave the current ones on and toss one of the big ones in your tool box as a spare.
