I posted this in the general discussions forum also, I actually meant to post it here initially.


Hey guys, I've got a vibration that just showed up on a 2002 Liberty Sport that I need some help figureing out the cause.

192,000 miles, OME spring lift, Moab wheels, 265/70/16 Goodyear duratracs.
I've just recently had some work done, and will give you a quick recent repair list, in case it gives you some needed info to diagnose this.

Within the last week or so......
Changed left side cv axle, right side cv axle, intermediate shaft and added a clevis lift.

Everything was good for a few days, then my starter went out.
Took it back to the shop to get the starter changed, and while it was in there, replace the front pinion seal, and rotate tires.

When I got it back, it has a pretty good vibration that starts at approx 40 mph, vibrates thru 50-55 mph, clears up a little, but is still noticeable.
Probably the worst at 45 mph.
Vibration is kinda like a washboard dirt road vibration, but not that drastic.
If you stay at that speed, it will make a droning sound.

Assumed it was a tire out of balance, although it drove good before the rotation.
Went back and balanced all four tires, but the vibration is still there.

Came home and pulled out the front driveshaft, and the vibration is gone while driving without the front driveshaft.

Any ideas?????
Please let it be something simple.
Within the last 3000 miles, I've also rebuilt the heads, and replaced the radiator.

Thanks for your help.
