Solutions are in listed in the order they should be performed
Body roll, most noticeable when entering/exiting driveways
Adjust tire air pressure per vehicle weight, replace/upgrade shocks, check bushings, replace/add anti-sway bars
Rough ride when pavement is rough
Adjust tire air pressure per vehicle weight, replace/upgrade shocks
Continuous steering corrections
tail wagging, wandering, road ruts, side winds, passing gusts
Adjust tire air pressure per vehicle weight, check bushings, replace/upgrade shocks, add track bars (if leaf spring suspension), add steering stabilizer
