I am having a problem with my 02 GP. When I turn right I hear a single loud thunk. Sometimes I "think" I feel a slight vibration in the steering as well. I also get a less loud thunk when I go over a bump. Any suggestions as to the most likely culprit? I thought to check the ball joints, but ALLdatadiy says I need a dial indicator to do this and I don't have one. Any other method to check them? Thanks for any help. I did a search and did not find another post like this one.
