loose lugnut, wheel bearings, cv joint, u joint, bad tire(s), it could be many problems. i would start in the order mentioned and go from there. just dont go to a mechanic saying "i dont know what this noise is.." they are likely to soak you with more to spend.. hope that helps..
water/friction
A continuous thumping noise and floor shaking while driving on a 2000 Honda Accord could mean a loose exhaust system. It could also mean a bent frame or a broken spring.
Bass
the noise coming from this truck is the uv goints
Bad tire? Rotate and see if thumping changes
Type your answer here... Rims bent
Maybe that thumping noise is the sound of another car smashing into the rear of your car.
worn cv joint =[
IT COULD BE A BREAKDOWN IN THE TIRE CORDS, HAVE A TIRE SHOP CHECK IT OUT. IT HAPPENED TO ME.
worn torsen differential
Need new lifters
Have that tire checked sometimes the belts inside can break and cause a thumping noise
