limited slip diff
My friend has a 02 superduty and i noticed that is has small vibration or wheel hop if your taking off and turning at the same time could this be from the limited slip diff or maybe something wrong.Mine has open wheel i believe and i dont feel that.I did notice worse when it was cold in his truck and as it got warmed up it wasnt as bad.It only last about 3 secs and only at very low speeds like when you first take off after that you can haul but beat it and what ever and dont feel a thing.But i thought i would ask everyone on here for him before something major happens.Thanks

Just go to the Ford parts dealer and get a bottle of friction modifier and put a little bit at a time in and test drive until it's smooth as you want it. It just makes the clutches in the LS less grabby. The more you put in the less the LS will work though so don't put too much in.
