for me:

there is an e-brake cable on the driver's side that was ziptied down to the control arm. the ziptie broke allowing the wheel (which had the wheel weights on the inside of the wheel) to hit the line. everytime it came around i got a "fwapp". put a new ziptie and all was well.

get down on the ground and look.

there's also a clip you can get to negate the need of zip ties
