I have a weird “thumping” noise coming from the rear drivers side wheel area.
It does it only when I hit a bump and seems to do it more when I am slowing down/breaking. The very odd time it goes from a loud single bump to almost a vibration. I have only heard it do this once, but my wife said it has done it a couple of times. The vibration only seems to do it while braking over a large bump, but again it is rare.
It sounds more like it is coming from the inside than the outside. I took the wheel off and checked suspension. I thought it might have been a loose shock mount, but everything is tight. I had my wife drive while I sat in the back, and it is almost like it is coming from the inside, but I have no idea what it could be. I might have thought it was the sub with a loose connection (is it in this area?) causing it to “thump”. When I had the tire off it appears the brakes are new (new pad and rotors)
It is not the access panel to the jack or the jack itself, as I removed them and it still did it. I also tighten the spare tire as I thought that might have been bouncing.
Mine is loud enough. Whether or not it's normal--I'm not sure, but mine has been great so far. I don't know how loud your radio was at the time, so I can't comment on that.
Radio was not really that loud. can still have a convo with the passenger.
as I was pooking around tonight trying to find the source, my son slammed the passenger door and I heard the thump in the rear. So I am leaning away from suspension. the more I think about it the more I am thinking sub with a short.
Is the sub in the rear drivers side under the window?
