1. Incorrect wheel alignment: Even though you had a wheel alignment done after the work was completed, it's possible that it wasn't done correctly or that the alignment settings have shifted since then. Have your alignment checked again by a reputable mechanic to ensure that it is within specifications.
2. Uneven tire pressure: Check the tire pressure in all four tires and make sure that they are inflated to the recommended pressure. Uneven tire pressure can cause your truck to pull to one side.
3. Worn steering components: In addition to the lower ball joints, there are other steering components that could be worn and causing your truck to pull to the right. This could include tie rods, inner and outer tie rod ends, idler arm, Pitman arm, or steering rack. Have a mechanic inspect the entire steering system to identify any worn or damaged components that need to be replaced.
4. Brake issues: If one of your brakes is dragging, it can cause your truck to pull to one side. Check to see if one brake rotor or wheel hub is hotter than the others after driving for a while. If so, you may need to have your brakes serviced.
5. Faulty suspension component: A bent or damaged suspension component, such as a control arm or strut, could also cause your truck to pull to one side. Have a mechanic inspect the suspension system for any abnormalities.
It is important to have your truck inspected by a qualified mechanic to diagnose the exact cause of the problem and ensure that it is repaired correctly.
