Over the past few weeks my runner is testing my patience. This new noise has me close to the edge. I left work yesterday. It was raining pretty good and with the wipers on, Defroster, and radio I thought I heard a thump, thump, thump. So I stut everything off and sure enough.... rock in the front passenger tire. Pulled over and looked......and looked, and looked some more. No rock. Got back in and drove a few more miles. I can not get the noise to repeat itself, it just kind of comes and goes. turning doesnt affect it, braking doesnt affect it. throttle doesnt affect it. But it is a rotational "thud" like a rock in the tire. Got home and looked over everything. I figured maybe a band clamp on my CV boot was broken, something caught in the driveshaft, loose molding, nothing. only thing i found was my front wheelwell liner was torn. Ripped it off and i still have the noise. So this morning I drive to work and the noise seemed to get louder on the way to work. Then tonight the noise is even louder and it seems to be coming from "under" the console. I can not see anything but everything see,s to be working fine I just have this thumping. Any Ideas?
