2005 F250 FX4 limited slip rearend makes vibration
I have a 2005 F250 Fx4 with a limited slip rearend. It makes a vibrating noise when going around corners when it is warm. I added fords friction modifier and it helped some. I have heard I have to change the "clutch packs" in the rearend. Is that true and if so how hard is it to do?
