I have an intermitant noise that is a rythmic clunking coming from the driver far rear, sounds like the muffler/exhaust area.
It happens once driving every few weeks, but once it starts it doesn't stop until I come off the go pedal, or stop. I have thought it was the muffler banging the underbody until today, when I was driving with it thumping, it sounded more like the noise was in tune with the rear wheel turning speed. IN other words it increased and decreased with the rotation of the wheel I thought. But coming off the pedal it would stop.
In my 45 minute commute I only heard it start the last 10 minutes...

I've never paid much attention to this mount but it sure has my attention now!
It looks to me that 2 bolts attached this arm to the mount but they are now gone. Does anyone know the size of these bolts? I'm thinking I should be able to go to the hardware store and get the proper size and length bolts and nuts and be good to go.
Anybody ever had to deal with this issue?
Thanks
