Why do we lift our Jeeps? More than likely its for the same reasons. Jeeps where not bought to have tiny tires and wheels on them. After you lift a Jeep you raise the body higher off the wheel giving you more room to stuff bigger tires under the fenders not only for higher ground clearance, but as well the look they provide.

After you install your 3 or 4-inch lift or even larger you will notice when you accelerate and decelerate there is a slight vibration coming from your rear end. What is it? Its your driveline vibrating from the extreme angle you've put it in lifting your Jeep. You look at your driveline and it doesn't look to be very extreme. In your mind it isn't, but to your drivetrain anything over a couple degrees from the rear end to your transfercase is extreme.

There are a number of things you can do to correct this small but possibly damaging to your U-joints and other drivetrain sections. You can revert to stock, you can lower your transfercase with a few 1-inch spacers, you can install a bodylift/motor mount lift combination, however the only true and real effective way of correcting this problem is to install a SYE "Slip Yoke Eliminator" Stockers come with a slip yoke in the end of the t-case for the driveshaft to slip into. With bigger lifts, usually around 3" to 4" and higher, there is a bind. The SYE does 2 things, it replaces the end of the T-case with a fixed yoke (what the driveshaft attaches to) to allow for a longer driveshaft and allows the rear shaft to be removed without loosing fluid from the T-case. However not only will you have to purchase a SYE kit, but you will have to purchase a new longer driveline with a universal joint.

SYE was purchased from our friends over at Northridge4x4.com, Dave gave me a great deal to get me started on this project as well I am matching the SYE with a driveline from him. Write-up by kizer, if you have any questions or comments about this install visit.
