I have a vibration in my 95 YJ beginning at 25 MPH. It's not the front end because when I can put in neutral the vibration will go away. I've posed this question on this forum before but all I got for replies was "change the U-Joints". The U-joints are fine and tight. I can't figure it out.

drive line angle. drive line out of ballance. tires out of ballance. does it feel like the vibration is more in the steering wheel, or in the seat. I would check tires first. most tire places do a poor job on ballancing.

another thought. check the two bolts under skid that holds the tranny mount, the mount itself, and theres a small rubber mount off the t-case, check if tight or still there.

I agree with Flatline - something is bent or out of balance

I don't know if you were referring to my question or the other guy's problem but I will check that tranny mount. Where exactly is it? When I'm underneath the vehicle the only thing I see is the skid plate. The tranny is pretty much obstructed by it.

I found the tranny mount and it appears to be fine. One thing I didn't understand though was that beside the tranny mount there's a bolt with a rubber bushing that doesn't seem like it does anything. It's tight and all but it appears unnecessary.
