during acceleration there i feel vibration between 40 and 60 mph, and then equalizes after that. im thinking its eaither my warn suspension or my drive shaft. my speculation about my suspension maybe so because when a make a deep turn (as if im making a u turn) there is a loud clicking sound coming from my right side. i dont know what part of the suspension that is. my speculation about vibration while acceleration is because i felt it violantly one day and i say that 2 bolts where missing from the U joint, and the other 2 where ready to go. i replaced the two bolt that where missing and tightened the other 2. all 4 are still there, but still there is vibration. please bestow me with ur wisdom,:icon_surp
