Another Vibration question ...

I've been looking through the vibration posts, and I haven't yet come across one that seems to match my current problem.

Recently, I've been getting some vibrations from what seems to be the front end/engine area, primarily when accelerating. The vibrations tend to let up when I take my foot off the gas. Along with the vibrations, my engine, or something in my front end, is a lot louder than it once was. The only thing I can compare it to is when your muffler first starts to go. My Jeep sounds meaner, but I know something isn't right.

I am also feeling the vibration up through my steering wheel.

I took my Jeep to a local mechanic. They're good guys, but not necessarily Jeep experts. They couldn't seem to find any blatantly wrong with my suspension components.

My Jeep is a 2000 XJ, with a 3" Rancho lift, 31x10.5x15" tires, a Rubicon adjustable track bar, and my transfer case was dropped a few years ago after I had to get my axle rebuilt.


Anyone have any ideas of what could be causing this? Is this something I can have my local mechanic take care of? Or would I be better served to travel the 25 miles outside of town to see a Jeep/4x4 specialist?

A front driveshaft that was not greased right. Mainly the slipyoke shaft. My other guess would be to check your motor mounts. Sounds like they may have shifted the motor thus causing your exhaust donut gasket to leak or crack your manifold which is not as common on your manifold style.

Ditto on the motor mounts, was my first thought after reading the symptoms....

Thank you for the quick reply. I've made an appointment with my local mechanic to have my motor mounts/driveshaft/front end looked at. I need a tune up anyhow. Might as well have everything thoroughly inspected.

I'll follow up once I find out what the issue is.
