[QUOTE=""Risky Bizness", post: 1037121, member: 74652"] [B][I]I had 3:55 gears in my 2010 F-150 with a 5.4 V8. It had the dreaded "rumble strip" vibration when turning. The truck called for friction modifier. The tech at the shop told me that instead of "1" bottle of the modifier, to use "2". ALSO, to take my truck to an empty parking lot, and turn sharp turns/circles about a dozen times each way to break the clutches loose. I did as he said, and the "rumble" went away. Find out and see if you have a L/S rear end, and get the proper modifier if needed, from FORD. As I recall it was around $8.00/bottle.[/I][/B] [/QUOTE]
