i have been running my Jeep with out an SYE for about 10 months now, i didnt install one when i lifted the truck cause 1) i didnt know i needed it. 2) when i found out i did need it i didnt have the money. 3) to start off my vibes wernt that bad, over time the vibs started getting worse and that usualy means eventually something will brake right? so what am i harming by not doing this SYE or T-case drop for that matter, is my T-case going to blow up soon?

i know i shouldnt be sucha lazy *** and get a sye or drop under there but i really cant find the funds for even a hackntap, do i got to bite the bullet and put something on the charge card or is it just the noisy vibrations that happens from not doing the sye


00 XJ
4.0
3" lift
np232

with only a 3'' lift just put a t-case drop on it, and if they dont quit, then its somethin else like bushings or your trackbar

 

At least do a t-case drop you can even make it your self. it consist of 4 longer bolts and 1 inch steel spacers.

 

I would also like to know if its just a noise thing or gonna mess up the tcase???

 

i actualy made one but didnt put it on rightaway and have since lost it


i dont have many tools around the house and my job has been telling us we cant work on our own cars there, i guess i can make another drop and see if the vibs go away

im still trying to find out if i could have already damaged something

 

either way if there is noise or vibration something is not right so sooner or later something will go bad take care of it now before it cost you in the long run.

 

Pick your posion a T case drop will kill your trans and motor mounts but the SYE costs a lot of money.

 

you can use steel shims.

i think with not running an SYE, you will blow a ujoint in the rear ds before your tcase actually blows up.

 

Shims are a good point im throwin some in when i put on my lift just to be on the safe side.

 

It's most likely bad u-joints. However, I'd do either a SYE or Tcase drop once you put new u-joints in so as to avoid the problem. I doubt it's your actual tcase.

Xmas isn't too far off, put a HnT, Spicer Adapter (Part No. 211229x), and front XJ driveshaft on the Xmas list. My SYE setup (the aforementioned) cost me something like $150-175 including shipping for all three parts.

 

Do what i did, 1" t case drop (home made) my rear driveshaft yoke shortened by about 1", put that on a 88 cherokee shaft(this shaft is slightly longer and thus reduces the angles.) works well with my lift no vibes at all!

1998 xj , 3" pro comp lift , aw4 , 8.25

 

I had some massive vibs today, so i think something finally gave out i took a peek under it but nothing seemed broke i will have to take a better look later on a lift at work, im thinking the u-joints for the front drive shaft are toast

part #32 is probably the culprit. i had 2 of them go bad within 1 year even with a t-case drop. crawl underneath and try to move the yoke. if there is a lot of play, then that bushing is bad.

 

part #42 is what you probably need it a hi angle yoke
if your yoke looks like the one on the left you need one like on the right part #42

 

Thanks guys i will have a look at it later and try and get one of the tecs "trained" eyes on it also

mike, is the difference there just the clearance i haven't looked at it to know which one i have but i will keep it in mind
