Over the last six months I started hearing a cracking/popping sound coming from under the van on every bump. I comes from bump I hit no matter the wheel. It has an sensation of the floor warping or wobbling as I can feel it through the floor under my feet. At first I thought is was the spare tire under the van's rear shaking but it is not loose. The exhaust pipe does not seem to be the problem either. It has gotten much worse now and I have not a clue what it is.

Hello,

This sounds like you have a sway bar mount or link that has gone bad. Is there a chance you can record the noise on your phone and upload in here in your reply so I can know for sure?

This video will give you an idea of what to look for and how to do the job.

Please let us know what you find.

Cheers, Ken
