Hello Everyone. I have a 2010 Ford F150 HD 4x4 that is Black Lava. I bought it used as it had low miles and previously owned by a church. I believe it has been lowered some especially in the front. I want to correct it back to factory ride height because I feel the ride quality is too rough when I come across bumps/pot holes. What should I be looking at? I have compared my spindles to those of similar f150s in the junk yard and they appear to be factory spindles. Is the only other possible factor the springs? Thanks!
