Tailgate opens, & closes hard. Torsion bars or what ever need oil, how?

 

also, engine light on, autozone pluged in and said O2 sensor, which one there's four? Is it cheaper to go to ford dealer. or replace all 4?

 

I had to oil my torsion bar. What i did was open the tail gate and you will see a panel you can remove on the backside. Maybe 8 bolts to remove. Once you remove the panel squirt oil down into the bottom of the tailgate and cover the bar in oil.


Did you copy the codes they gave you? The code will indicate which o2 sensor needs replacing. Whats your mileage?

 

No i didn't write the codes down. I have only 50,000 miles on the truck
