Hey guys no luck with a forum search so I figured I'd ask. I own an 84 Rx-7 gs with around 93,000 miles, and sporadically, while driving at low speeds (5-15 mph) I'll hear a rhythmical clicking from what sounds like the rear end of the vehicle. The sound is hear when my window is down, so it's definitely not coming from inside the car. (For a minute I almost thought I wired something wrong with my speakers)

 

Check to make sure you haven't picked up a rock in your tire tread.

Seriously.

 

i would say if there is no rock it would be a bearing getting ready to go.

 

Haha I get the rock all the time, I've learned to ignore it. For some reason the RX-7 is the only car I've ever been able to hear rocks clicking in :P
