i have an 01 5.4 4x4 lariat with only 16,000 miles on it and i do my fair share of off roading and mudding. i have wd-40ed most of bushing pieces in front suspension and other parts where i could imagine where it would be but no luck yet.
-what could it be mayb shocks? idk not enough miles in my mind?
- the truck had been sitting for a good 7 years(reason for low mileage)dry rot bushings?

as for power sterring i was thinking it couild be pitman arm needs to replaced or greased up not sure. its loudest when moving tires stopped and slow turns.
