ok so its a soft thump at low speeds and louder and faster as i accelerate, but doesnt go away. when i rolling around 10-15mph it thumps consecutively and the front driver side lifts up like someone is jacking it up about two inches and dropping it back down repeatedly. when i go faster like on the freeway itll shake but not violently. i can also feel it in my steering wheel but slightly.

i switched the back wheel to the front and its still doing it. ive checked lower ball joint (replaced a couple months ago), tie rod (looks ok but almost beat up, no play in it tho), axles, rotors, and pads

any suggestion i should look for

 

Shock blown?

 

i dont think so. shocks aren't leaking and car doesn't flop around when i hit pot holes or dips. it rides like stock even though its on tein s techs

im gonna change out all four wheels with another set i have in the garage hopefully that thump sound and vibration goes away

 

Make sure it's not blown. Don't guess.

 

issue resolved! it was my tire it has a dimple about 1/2 inch inwards, barely noticeable.

 

But if you switched wheels front to back that doesn't make sense.

 

yeah i checked again and theres a nail on the front driver and the other has a dip in it. didnt make any sense as to why it made the sound and vibration but it all went away when i changed all four wheels (15in LS mesh). then again maybe bc the original wheels (14in steelies) on there werent balanced, but then again ive been driving like that for a couple months without the issue.
