I must have had a rock or a piece of gravel in my rear wheel because there was and awful clunking noise and the brakes were acting weird. After I drove it into a parking lot and went forward and backwards for a while the problem stopped and now it's back to running normal again. It really had me worried there for a while, it felt like my wheel was coming off.

My driveway is gravel and maybe it picked up a stone while I was backing in, cause the problem started right after I left my driveway. All is well now.

 

My rocks like to fly off right when I hit 60mph on the highway, sounds like someone is shooting my truck.
