Thump/Bump sound underneath driver floor?

[Forza]

I frequently hear a thump/bump sound right under the driver floor. Usually here when I move or come to stop. Anyone else hear it on your '05 SR5?

Forza it may just be your seat rails/mounting. I think I have the same sound going on right now and haven't had a chance to check but try sitting in the chair and moving back and forward somewhat frantically. I mean, don't hurt yourself, take it a little easy but go ahead and move your upper torso forward and back with moderate vigor.

I'll try it..but the sound seems to be coming from underneath..will try.

Let me know how it goes.

I had a similar issue a while back, it turned out to be a sway bar bushing that needed replacing.
