On my way home today from work im driving along i hit and bump not even a big bump at all i then hear a rattleing type noise then BAMMMMMMMM!!!!!!! my rear end blew...no signs no noise before this nothing...Im thinking Something to do with the ring and pinion?...the car goes into gear the drive shaft just spins....the rear is free moving...then when i put it back into the park you hear the trans parking brake clicking because there is no way i can stop the driveshaft from spinning no rear brakes to stop it......So the car is an AOD with 3.27's should i do the stock gears or go bigger this is my daily tho by the way...Now I have 2 mustang's in the stable...and no way to get to work this sucks!!!!!
