I have a 95 YJ w/ a 4 inch RC suspension left and 1.25" lift shackles. I run 33x12.50 KM2's. Stock 4 banger with 4.10 gears.
I recently have removed both track bars and front sway bar. When the Jeep is stationary and let the clutch out in first, the whole drivetrain seems to shake pretty vigorously. This is worse when stationary and I start rolling in reverse. I'm going to go over the whole rig tomorrow to make sure all the spring bolts and U-bolts are still tight. It started before the removal of the bars, but now I believe it's more pronounced. Also, sometimes it happens and sometimes it's pretty smooth.
Is this axle wrap or wheel hop? How can I reduce or eliminate this because I don't need to be breaking any drivetrain parts.
Track bars on a YJ...hmmmm.... I drive a TJ but had to help a buddy with a YJ. Yup, axle wrap. On a lifted jeep the only method I know to stop it is with a truss kind of control arm. You have got to stop the axle from rotating. If you dont the next thing to break is a U joint or the leaf springs.
"If you have significant difficulty here, dont go any further....it only gets worse".
Is your drive shaft stock? Do you use a t-case drop? Sounds like your DS angle might be the culprit, take a couple pics of it and we will be able to help out more
Edit: Is your lift SOA or SUA? With an SUA lift your not going to have much of a problem with axle wrap and it's definitely not wheel hop that's your problem if your jeep is shaking when you take off, I've been driving my YJ without track bars or sway bars for over a year and a half and no problems, I do however have bad axle wrap because my springs are worn and I'm running a SOA lift.

From your pics, it almost looks like the pinion is not in line with the drive shaft and actually pointed up. When you get on the throttle, your pinion will go up even more, and possibly give you the vibe. Mine is pointed down 3-4 degrees so when I am on the throttle it will rest in a neutral position. A 1" t-case drop and a SYE will also help. I had to swap rear u-joints every month until I did the SYE because of the severe angle.
My suspension is sua. The springs are 4 inch lift springs. Im experiencing a shudder when accelerating also. I'm running a 6.0 vortec with a couple power adders, bout 330 hp. Is it possible that the springs just aren't stiff enough to handle the torque of my engine?
