im getting this feeling in the body at like 1-20mph like im going over a bump in one of my back tires

i did a bit of research but majority of the people are saying steering wheel shake but its the a body shake

tires look fine.

maybe i need to balance them, but i would think that you would feel that more at high speed. rim looks fine, florida roads dont have much pot holes,
would warped rotors do thats? suspension seem fine too,
maybe a sway bar, bushings? dont have much money to try and fix something and its not there? any ideas guys?

 

no noise for wheel bearings, and checked all the ball joints and tie rod

 

It sounds like flat spotting or separating tread.
If there is any sort of bump visible anywhere on the tire sidewall, the problem is the tire. Might be a bent rim, too; IDK if that gets worse at higher speeds.

Rotate the tires from the front to the back and vice-versa. If the problem moves to the front, it's a tire/wheel problem. If not, it's something in the rear suspension.

Any mods to the suspension or shocks?
