my car is there right now because i was an idiot and slid it into a curb doing about 40 havin some fun during the storm. everything is cool with insurance but the dealer wants to replace 2 tires instead of all 4 like it says to in the manual. i dont want it to screw up the diff's by them now following procedure. anything special i should tell them or call someone and let them know in case something does go wrong?
