I had a thump or clunk sound. Check your shocks . Make sure they’re mounted up tight . My left drivers side was found loose.I have a 21 platty tremor with 11K miles on it now. The truck runs and drives great, no complaints with it except that it has developed a dull thumping sound under the truck in the last couple thousand miles. I only notice it at low speeds while driving over bumps. I think its in the front end but the truck seems to transmit sounds through the frame so its hard to pinpoint exactly where the noise is coming from. I don't hear it at higher speeds but I think it's there but masked by road noise. The dealership did a quick look at the truck (whatever that's worth) at the last oil change and said everything looks good to them in the front end. Anyone else have any experience with this or know where I should look first?
I’m going to investigate the spare tire
