first, make sure you're not driving a tj.


seriously tho, if it's coming from the front, check your ball joints and hubs, if it's from the rear, check your shackles to see it they're seized.
maybe you have nitrogen shocks, i don't like them as they will give a harsher ride than hydro shocks.

new ball joints uper and lower and shackles move freely re super ride so it should be hydro shocks

Go with the RC kit!
