There isn't a detailed description on jeepinoutfitters as to what the differences are between this SYE kit and he others listed, and the pictures leave something to be desired.

It seems like a pretty good price, assuming I can locate the DS and spicer part locally.

with the HnT you need the spicer part unless you are buying a tom woods custom drive shaft in which case you can ask him to put one on for you but your still going to have to pay for it.

but basacally the spicer flange is the only thing that can connect to the HnT flange (there is one other but i wont go into that)

thank you for your support. it is a sticky in the tech/faq sticky located at the top of the cherokee technical forum. but there are enough stickies as it is, it would start getting cluttered if this one was added to the top. even though i think it would be very useful for a lot of members to see it there.

again thanks, and im glad you like it

thanks a bunch for posting this thread. Ive read it several times in the last few months, and i think im about ready to get a SYE now. After reading, im pretty sure i have this right, but just want to double check. I plan on purchasing this:

http://www.jeepinoutfitters.com/scri...?idproduct=567

which replaces the output shaft. one of my buddys has several front driveshafts from various cherokees and grand cherokees, so as long as they came out of a 91+ cherokee or grand cherokee with an auto transmission, this drive shaft will work just fine correct? id eventually like a tom woods DS, but for now id like to save some money for other things (like my wedding in april!). sorry for bringing and old thread back to life, i just wanted to make sure i was correct before i start shelling out the cash. also, i have an 8.25 rear end, not sure how much that matters. right now, i think i will need the HD SYE kit and a front drive shaft. anything else im missing?

thanks for the help!

Just read through this, great information. It may have been mentioned, but I don't recall, it's my understanding the OEM front CV drive shaft won't work unless you have a fair amount of lift, like 3.5 to 4 inches or more because it's too long, in particular on the later models like mine with the 8.25 rear. So it's a bust for say a BB of 2-2.5 inches on these later year models which seem subject to problems with even minor lifts and you end up having to buy a shorter custom CV shaft when you install an SYE. Am I correct in this?

Fortunately they WILL work with as little as 2" of lift. I have 2" of lift and run the hack n' tap/front DS just fine. I have the 8.25 rear axle and np242 t-case which both effectively shorten the rear DS and it still works. If you had a d35 or d44 it would work on stock height. I had to extend my bumpstops about an inch to be safe on bottoming out the DS but I probably would have been fine on stock bumpstops too.

The cherokee and grand cherokee front DS are different. I would find one off of a regular ol' xj since you'll know it will work. I've heard of people using GC front DS on higher lifts since they are longer though.

91+ auto 4.0 xj front shaft is what you want. It will work perfect with 3.5" of lift and the 8.25 axle. You'll want to rebuild the front DS before you put it in there.

no worries about bringing the thread back, i encourage people to do so.

your setup sounds fine, get the HD sye and put a front DS from an auto tranny XJ back there and you will be just fine. As dopod said make sure you rebuild the new front DS with new ujoints.

ok, I've read through all the posts, I think- got a question. My setup- 2 inch spacers up front, 2" AAL in the rear, (stock shackles) 30x9.50 tires on stock 15x7 rims. 96 4.0 w/ aw4 auto tranny, 8.25 rear, 231 tc. Got vibes immediately, so I bought the RE hack-n-tap, spicer flange and front shaft out of a 93 xj. Got everything in the garage, waiting to go in. So, those with experience with this setup, will I need any shims to get the angles right, or will the axle to shaft angle be where it needs to be? thanks

**XJK** · 11-04-2007, 07:54 PM

with 2" you should be all set to go with just the SYE. Your pinion angle wont be too much of an issue at 2".

-Kyle

citRon · 11-04-2007, 08:07 PM

cool. I got about 2 1/2 inches from the AAL's, maybe they'll settle some, maybe not- I'm impressed with the Black Diamond stuff- pretty thick leaf, and rides nice too. Oh, yeah, new shocks too - I did the Rock Lizard suggested Monroes and used rear swaybar mounts for BPE's. I'm pretty happy with it so far. I think I'll be really pleased with it when I get the front shaft and sye on.
