Hey everybody, I'm hoping for a "collective diagnosis" from you guys. After a highway trip the other day, I was taking a slow corner at a stop light and heard a 'tunk' sound coming from the driver's side rear wheel. After investigating a bit, it seems to only happen at slow speeds when I'm turning. When I'm over 10 mph or so and/or going in a straight line, it's not there. It goes 'tunk', 'tunk' at a slow, unpredictable rate, almost like the axle or wheel is getting hung up internally. What do you guys think? I'm a shadetree mechanic with my trusty service manuals, so any help saves me from paying to get it looked at. I can usually fix things if I know what the problem is... THANKS!
