Axle wrap? Wheel hop?

Quick question.

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.

Thanks for the help guys.

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.

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.

Stock shaft, using the RC t-case drop. Never really had this problem when I first installed the kit. I'm wondering if I put the track bars back on if it would stop the problem.

do your shifters bounce left and right if so it is probably the tranny mount and stabilizer. If these are bad check the engine mounts they usualy aren't far behind

Also, when in 4WD, it's almost non-existant. Check the spring bolts and u-bolts, those all seem to be tight.

Yes, it does, pretty bad actually.

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.

Thanks for the input. I've been running my setup since last fall. If it was the pinion angle I think it would have started back then?

I'm going with the mounts first since they're pretty cheap. 150,000 miles on the rig, probably worth changing them anyway.

i doubt your 4 cyl is causing axle wrap and wheel hop lol. maybe a sbc and soa and youll have that problem

also check your driveshafts because if your u joints are shot that will cause that vibe..my front driveshaft is about to snap in half and i get alot of vibes from it lol

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?

In a completely different track, how's the clutch?

If you get oil on the clutch, like from a bad rear main seal, it will make the clutch shudder when being engaged. It will feel like the drivetrain is shaking, but it isn't a vibration.

If it smooths out when the clutch is out, and only shakes when you are starting out, it might be clutch related.

You might also have someone watch your driveshafts and u-joints when you start out to see what looks like it is making the shake.

Your angles look fine and your slip yoke is dirty so it does not look like it's riding out any further than it has for a while. I am thinking clutch shudder or maybe trans mounts?

Could the short length be a factor?

Wow forgot about this thread. Ended up being a chatter from a bad clutch. Hotspots on the flywheel as well. Replaced with a stock Sachs clutch and flywheel. Back to normal.
