Does your rear axle sit more towards the passenger side than the driver side? Mine seems to sit slightly towards the passenger side and I was wondering if this is normal on these F150s.

 

should sit center should it not?

 

mines a hair towards the pass side, you dont notice it until aftermarket wheels or bigger tires really

 

I didn't notice mine until I went from the 275 to 305 tire.

 

Unfortunately, it's normal and deemed "acceptable" by Ford. They have very wide body part locational tolerances. I think they are either +/- 0.5" or maybe it's as extreme as +/- 1".

You could try to adjust the position of the bed. Some have good luck with this others make it worse.
