Just about everytime i take a turn i hear a clunking noise.. im not sure if it is coming from the front end or the back. but when it does it it almost feels as if i got hit and it jolts sideways. the 4WD seems to be working fine and the CV axles and tie rods seems fine. any other ideas would be appreciated. it is an 02 with around 72000 miles. only mods are sound system and thrush exhaust.
