SYE and CV drive shaft- Rough Country

Alright guys, help me out here. Rough country makes a SYE kit and a CV drive shaft to go with it. I have a 2001 XJ with a 3" lift, an NP231 TC and a Chrysler 8.25 rear axle. I am thinking of buying this kit because I am still getting some vibrations at or around 65+ MPH on the high way. Also, when I engage my 4x4 every now and then it doesnt want to disengage. Not always but every once in a while.
Would the SYE help with this issue disengaging issue?
Would this help with the drive line vibrations I am feeling at 65+ MPH?
Does anyone know if these are good parts? I cant find any reviews on them.

Help point me in the right direction, please.

The 4x4 disengagement thing will not be helped by adding an SYE kit (at least not that I have ever heard of or can see how it would). Mine does that too sometimes, I simply stop, back up a little bit in reverse and then drive forward, pops right out. Same thing, not all the time but once in a while.

The SYE will completely remove all vibes and drive-line noise. This appears to be the Advanced Adapters HD SYE and the Tom Woods DS. Both are top notch components. I have had the AA SYE for 4 years now, works amazingly well and is well worth the money/effort.

If you want to go cheaper, you can grab the AA SYE and a front driveshaft (double cardan style) from a 4WD Cherokee XJ and use it as a rear shaft with this SYE. I did that, and have picked up a spare, so I have 3 identical drive shafts and I got both for $100 bucks.

I have read, and been told, that high speed vibrations are caused by balance issues.
SYEs address driveline angles, which cause LOW speed vibrations.

When you say you are *still getting* vibrations, have you tried to mitigate them somehow and it didn't help?

And some people think it's easier to install the SYE w/o removing the T-case (presumably with the Jeep on a lift!).

OK help me out here....I am researching an SLE for my 2000 XJ. I see many kits come with a CV shaft. What am I missing. That shaft is obviously shorter than the stock shaft. is there another component I am needing? While I have access to a lift and have always done all my own repairs, I would prefer to buy a complete kit and not have my jeep sitting on my brothers lift while I wait for more parts to come.

I found this web site what asks for the measurements. http://www.rockridge4wd.com/Jeep-XJ-...cv-sye-kit.htm. Are these any good?


I don't have any vibration but I do have a droning at 60 mph which could also be my pinion bearing or just a pinion angle (which I will be measuring tonight). But I should have a SLE with a 4.5" lit so I figure what the hell...

Ok I have a 96 xj and I've been having very bad sounds coming from my t-case.

I currently have a 4.5" lift and I do I have a T-Case drop kit installed. This helped with vibration issues but I am still having others.

I hear a clanking sound in the tcase when stopped then when I let off the brake and go at idle speed it's silent and feels smooth.

Then if I hit the gas and accelerate it's makes like a "wawawawa" (lol) sound that gets faster as I accelerate then fades away.

I also hear a droaning at high speeds

My question is, will a SYE resolve these problems and if so, what kind should I get?

I have a 1996 with an auto transmission, a NP242 transfer case, and an 8.25 rear axle.

See http://i.imgur.com/2LzzsKo.jpg this is a 28" drive shaft.

If I'm only lifting 3" do I need to consider this slip-yoke mod, or am I OK? Looking to put on Rough Country 3" lift.

i tried to read all in this thread, and behold... more i read more i got lost...

i have 91 xj 3,5" lift, 8 1/2" rear and 242 with homemade H&T sye, i been using stock front DS in rear but those seems to be a bit too short, im over extending my shaft when flexing out, slip joint is nearly on its end when in normal ride height and outflexing makes slip splines coming out of the dust seal, i have allready broke dust seal and my old dS that seal constantly popped off from its place, slip worns out rapidly and allready the one i have in now vibrates badly, uphills i have to use 4wd, wihtout whole car starts violent shake, good joint usually lasts about 1000 miles and then its toast.

i could extend one myself but balancing cv shaft is a bit tricky at home


some zj shaft seems to be longer but not so easy to find i think, and after all reading not sure at all if it fits or will it be too long and ill bottom it out, or did i just read all wrong here.
