just noticed when i was putting on new control arms that my gromets are missing on my caliper bolts.when i go down the road i always here a "clang"type sound and when i hit rhe caliper w a rubber mallet i can hear same sound.might be the cause?sount is coming from bolt hiting the bracket.

you talking about the little rubber bellows that slide over the bolts, if so I dont think that would cause a clang sound

But maybe the dust shield is rubbing on something or loose.

well replaced gromets and a mounting braket that was keeping the caliper from moving and made pad loose and it fixed my problem!}( but now i have a brake bleeding prob

Brake bleed problem huh? Whats the problem?

Well ive already fixed that problem to!lol
