If I was to install a SYE, would I need to modify the drive shaft at all or should it just bolt in place(after removing the slip yoke from the drive shaft that is)?

Thanks! 94 Cherokee 4x4 5spd Man 4.0

No, you will have to modify the driveshaft or with some of the sye kits you can use another front driveshaft for the rear

Depending on handiness, you can do a hack and tap SYE. you cut your output shaft to about half length, tap it, install kit.

You cant yourself modify the drive shaft, unless you can balance it and really weld ( and not the backyard welding) you either can have one made or do like the two above suggestions.gl

You don't mod drive shaft, you mod the output shaft with splines on it..

If you go with an SYE you absolutely have to change driveshafts. You will go from a single u joint upper joint to a double. You will have to do this because only the double cardan u joint will bolt to the yoke on the tcase end. The little straps will not fit without modification. And even if it did, you now have to have a slip joint in the drive shaft anyway.

You will also have to tip the pinion up to where the other joint has little or no angle between the shaft and pinion.

the double u joint, is it the same as the front drive shaft double u joint? trying to picture what you are talking about. didnt realize all this would be involved.

just read this ( http://liftyourxj.com/sye ) and its answered a lot of questions. thanks for input everyone!

Yes.

was just checking out the tom woods web site for drive shafts, $300 and im set. think i will be calling in an order soon =)

Is this due to the shorter drive shaft that will be put in, causing the angle to increase, thus tipping the pinion angle upward to compensate? or am I totally off on that...

how would you classify me. I know I can really weld, in my backyard, or front yard, or garage. (see links below)

I cut down a driveshaft and re welded it myself on my hot rod s10. 7000 rpm 130mph NO VIBES. shes smooth as a babys bottom, But ofcourse this wasnt my first time at the ball lol.

This being said, unless you know what you are doing and can really weld. Don't bother messing with driveshafts.

As for the SYE question. get a hack and tap, they are cheaper, and then a FRONT driveshaft will BOLT in place of the rear shaft.

I just did the dirt bound hack and tap with a front driveshaft in my rig this week.

Hmmm I can't classify you if I don't know you now can I. I was stating a simple fact that applys to 9 out of 10 people, now stop being an (j/k) nothing was met to insult anyone, just that to many people try to do things they know they shouldn't do. A drive shaft done wrong could result in a breakage at 60 mph an kill them or someone else or just cause injury. ( don't wish it on anyone) but it does happen.So again no insult meant but common sense is needed and from what I've seen in the generation currently it is lacking big time.

Tom Woods is a good outfit and makes nice heavy shafts, much stronger than the stock shafts. You won't be disappointed.
