Noticed a growing frequency of a "clank" or 'clack' sound when starting to drive from park. I think it is from the front end or mid, but not from rear as far as I can tell. Just had a 90,000 service done, and it was occasionally making the sound then. Tech found nothing, torqued the drive shaft bolts etc, but still making sound. Now, though, it does it forward and reverse, and mainly after it has been parked for a little bit. It does it most when the wheel is turned, and then moving. Any ideas or anyone else have this?
