Hi, i'm new to the forum and hope to get some help.

I have a 2005 Ford F150 FX4, it has a 6 inch pro comp suspension lift with a 3 inch body lift. I have 37 inch BF A/Ts on 17 inch rims. I have had a pile of alignments done and I also end up with a negative camber after driving for awhile. I haven't been doing a lot of offroad driving and it still happens. I orignally thought it was cause of hard bumps and things but it still happens on road driving.

Is there something I can do to at least stop it from happening so often? I really want to keep the truck but tires can be expensive when they wear out. As well as the constant wheel alignments are adding up, and I don't have much time during days off from work to get it done.

Any help would be much appreciated.
