Hello,

If the front shaft U-Joint has play in it the most likely that is the cause of your thunking. To confirm all you need to do is remove the front shaft and test drive. If thunking is gone replace U-Joints. Yes, replace both joints cause I have found that if you only replace the bad one the other will go bad with a month or so.
