    Rumor has it that there's a plastic star gear at the bottom of the steering column, but the parts diagram doesn't show that part. I already replaced all the tie rods and lower control arms but that sound is still there over bumps and can be reproduced when jiggling the wheel back and forth. Any opinions?
