All of a sudden my sway bar has started rubbing on one of my after market bumper bolts (driver's side near the stearing gear box bolts). I haven't changed any parts in over a year. I checked the brackets that hold it to the frame and they are all still tight. I don't see any cracks in the frame around the stearing box. Any idea where I should look for a cause? Can I just tap it with a hammer to shift it back? In case it matters, I'm using JKS quicker discos.

 

Tapped it over 1/8" using a 2X4 and no more rubbing. Unfortunately that didn't seem to be the cause of the clunking sound that i get when I apply the brakes when reversing. Bummer...
