I purchased a 2011 F150 FX4 last year. It had a 3" leveling kit and 35" nitto tires on it. After a few months I kept going through cv boots. Took it to a a place that specializes in lift kits and accessories. They said the boots were out of line because of the leveling and to either put a 2" leveling kit or a 4" lift kit. I decided to lower it for ecocnomical purposes. Long story short same problem. I don't do any off roading and only have it 4wd on rare occasions. Any suggestions? If I put the rough country 4" lift kit will my problem be solved?
