Hey all, have a 90 Z32 N/A recently started hearing some vibration on the rear driver side which turned into a clunking/vibrating sound. I can hear the sound when i am either coasting or very low acceleration. It will stop when i accelerate more. I can start with wheel rotation and other basic diagnosis but want to check if anyone had a similar issue. Thanks.

 

Fist check to make sure your lugs are tight.
Otherwise it sounds like:

1: the dust shield has something caught in it against the rotar
2: the dust shield is bent
3: something blew apart in the ebrake assembly
4: the caliper is sticking

Let me know if that helps.
