I recently had a shop install BMR lower control arms, adjustable third link, and panhard bar. Ever since then, whenever I begin to accelerate, I can hear one thumping sound coming from the suspension. You dont hear it anymore when you are driving, until you begin to slow down, then you hear another thump noise, and so forth. Is this normal because the bushings on the BMR are different than the factory ones originally installed? I just want to make sure my car isnt going to fall to pieces on the Interstate.
