I was reading on your site about a fellow who was experiencing a problem with his 1999 Jeep Cherokee. Here is the link to the thread.. Noise and vibration with my Jeep Cherokee
I am experiencing the same problem (all the way down to the speed at which he experiences the noise – 65-70 mph). I wanted to follow up to see if he ever got back in touch with you to let you know how/if he resolved the problem.
Your information was thorough and informative and I’m hoping he took a moment to let you know the outcome (and that you’d be willing to share that with me).
P.S. I replaced the two front tires and had a “factory” alignment of all 4 tires. I also had the lubricant changed in the front and rear differential and transfer case. I’m still getting the sound (although it’s perhaps somewhat less than before).
Thanks in advance,
If the noise changed…or you think it changed, I would switch the new front tires to the rear of the vehicle and see if things are worse or better…or stay the same. I am still going on my hunch that this is a tire tread noise issue. Keep me posted.

I wanted to follow up with you regarding the problem I was experiencing with my Jeep (see the thread above). After much frustration, I took the vehicle back to the original mechanic who replaced the front left wheel bearing. He looked at it and thought something might be wrong with the bearing in the front differential and recommended another mechanic who specializes in these issues.
Brought the car to the new mechanic and got a call from him a few hours later. He replaced the front right wheel bearing and the car rides perfectly silent now!!! Apparently the sound/vibration from a bad bearing on that side travels right through the shaft and can deceivingly sound like it’s coming from the differential. So it rides fantastic now and for only $225 to replace the bearing!
I thought you would find it interesting and perhaps helpful for anyone in the future.
Thanks again for all your help,
