for a couple weeks now ive had an annoying metalic noise when going over bumps slowly.

I had applied a rubber mallet all over the rear end components but could not replicate the sound.

Warm weather today inpsired me to take another look. . i noticed the driver side caliper mounting bracket was a tad loose.

Jacked up the car and removed the wheel, and i was able to tighten the lower nut a good half turn which solved the noise and secured the bracket.
