sye

I have a '92, i put on a 4" rough country lift here recently and it called for me to lower my transfer case. If i get a sye can i raise my transfer case back up to where it was?

Yes if you put an SYE and new CV Drive shaft on you will be able to remove the TCase drop.

Sorry to bring you bad news but---rough country has issues with there leaf springs. I installed that kit in July 2006 and my springs have gone flat It has also caused damage to other parts of my drivetrain. Keep an eye on your angles especially if you start getting vibration when you first take off. Also if your rear universal joint is impossible to change because it is soo jammed in there. Buying an SYE will benefit you in a future build which is always a plus or, you can go with 1/2 the spacer you have now in about 8 months when you have my issue

The actual TCase was bouncing? Or was it just the drive shaft at the TCase end moving around a bit? That's a typical problem with any jeep that's lifted and still uses the stock slip yoke.

If it's the case moving around then you might want to take a look at your tranny mount to make sure it hasn't given up the ghost.

yea, i looked up and under it and the tcase was bouncing around i figure it was because i got some bad angles so im hoping a sye would make it quit

Well definitely take a look at your stock rubber tranny mount. It could easily be causing the problem of your TCase/Tranny bouncing around. However the vibes yes you are going to need an SYE and CV Shaft to eliminate those.

If your kit is new, something else is wrong. At first I had no problems. When my springs started to flatten out is when my problems started. Check into it further first.

typical..the stock slip yoke is intended to slip in and out lateraly..when you first take off from a stop, the pinion yoke (whole axel) tends to rotate up under torque load..if the angle on your slip yoke is to great, instead of slipping in..it pushes your t-case up too..an sye will certianly help

Sye

ok, well i am going to go ahead and get the sye, but i am going to go ahead and get my jeep as high as i can before i get the driveshaft. that was the only reason i went with the 4" lift because i wasn't going to get a new shaft. i think i am just going to get the shackles that will give me 1 1/4" lift, that won't give me any more problems will it?

No, you should be fine. You are right in waiting until you are at your final ride height to order your DShaft.

my two cents...i have a four in lift..i have 8degree shims on the rear..i have an sye,,without the drop spacers..the angle of my rear driveline is too great..so i droped it back down...with an sye..the rear pinion yoke-should point almost straight at the t-case yoke..a few degrees low is actualy perfect (spring wrap) you really do not want an angle to your d-line out of the pinion...if you must keep your t-case up without spacers..i would go with a 'super short" sye..and possible spring perch re-mounting to swing the pin yoke up...
