Jeep Wrangler TJ Rear Driveshaft for SYE Lift Kits 936-085

This is a rear driveshaft assembly built for the 1997-2006 Jeep Wrangler TJ 4WD on the short 93.4 inch wheelbase. It is listed as a replacement for reference number 936-085 and is meant for lifted TJs, not stock-height trucks.

Two requirements before you order: the Jeep must have a 2 to 6 inch suspension lift, and a slip yoke eliminator (SYE) kit must already be installed on the transfer case. It will not bolt up to the factory slip-yoke output. It also does not fit 2WD Wranglers, the 103.4 inch wheelbase TJ Unlimited, or any 2007-up JK or JL.

The reason people run this setup is driveline vibration. Lifting a TJ steepens the rear shaft angle, and the stock single-cardan shaft on a slip yoke starts to buzz and shudder at speed, and the slip yoke can pull partly out of the case when the axle droops. An SYE with a double-cardan shaft like this one fixes the angle problem and moves the slip section into the shaft itself.

Install: support the rear of the Jeep, mark and unbolt the old shaft at the pinion and the SYE flange, bolt this one in, grease the joints, then set pinion angle so it points close to the transfer case output before the road test.
