Default SYE and front drive shaft question...

I am planning on installing a SYE on my 2001 Cherokee.

On the Jeep forums, I frequently see it recommended to use a front drive shaft with a SYE. In crawling around under my Jeep, it appears that the front drive shaft is quite a bit thinner than the rear drive shaft.

If I replace the rear drive shaft with a front drive shaft, am I losing strength in the rear shaft? If so, is it anything to be concerned about? It is my primary winter vehicle, not just an off-roader, so it sees a bit of road time in 2H.

In case it matters, the Jeep has a 3.5" RE lift, 4.56 gears, NP231 TC, chryco 8.25 rear axle, and 32" tires.

You have put some money into your jeep, Your DS would become your weak link. I would recco. buying an aftermarket one. If you were working on a budget build then yeah go for it. But with your set-up I think a aftermarket DS would be best for you.

Have no clue on SYE sorry I have a 242 T-case no SYE needed. Tom Woods makes a great drive shaft from what I understand though.

Why would the front drive shaft be stronger? The rear drive shaft gets more use, and the front is thinner.

Here's a combo kit that includes both the SYE and a new driveshaft. I'm no expert on this, I just did a quick search for you. This one is from Rugged Ridge and has a RE shaft...

And here's the Rubicon Express kit, I think it's a hack and tap though, which as far as I know is a bit different, but accomplishes the same goal...

I do know for sure that you will have to shim your axle to correct the pinion angle for the new shaft though, as the pinion angle needs to be inline with the shaft with a CV driveshaft, not parallel with the output as with a normal driveshaft. Hope this helps.

for a 231, check out Advanced Adapters SYE and a Tom Woods DS.
best setup in my opinion.

Does the transfer case need to be removed to do the conversion?

it does for the AA as you replace the output shaft instead of just hacking your stock one off.

That's what I figured. Probably makes it a bigger job than I can handle myself.
