Wow lots of replies. lol. Thanks for the input guys. i hadn't really considered the possibilty of driveline damage. I'm still not quite used the to the all wheel drive thing. this is my first all wheel car. I have a prob though. lately my car hasn't been wanting to lock into all wheel unless its in power mode which it hardly ever goes into. This is great for big smokey front wheel burnouts but somewhat disconcerting when you realize you just did a big smokey front wheel burn out in an all wheel drive car. I'm also getting a lot of rear end noise Im afraid the two things may be related. Any ideas on what might have happened?
