Wheel alignment out of spec is the single most common cause of a BMW pulling or tracking to one side during normal driving. This happens when the toe, camber, or caster angles drift outside factory tolerances, usually after hitting a pothole, curb, or accident. Even small deviations throw off the steering geometry and force the car to fight you on the highway or in a straight line.
What it feels like
You'll notice the car drifting or pulling to the left or right, even with hands off the wheel on a flat, straight road. The pull may worsen under acceleration, braking, or cornering depending on which angle is out. Some owners report the steering wheel sitting off-center to compensate. If the pull happens mainly during braking, brake drag or caliper problems are more likely, but alignment issues typically show up during cruise and require constant correction to stay in your lane.
How to confirm it
- Drive the car on a flat, empty road at steady speed and note which direction it pulls. Check if the pull changes when you cross the road crown or change lanes, since road slope can mask a real alignment fault.
- Look for signs of recent impact: pothole strikes, curb contact, or accident damage to the front or rear suspension. These are the most common triggers for alignment shift.
- Check tire pressure on all four wheels and rotate the tires front to rear. If the pull follows the tire and pressure is correct, a tire defect or conicity is more likely than alignment.
- Get a four-wheel alignment printout from a shop and compare toe, camber, and caster readings to your BMW's factory spec sheet. Out-of-spec numbers confirm the diagnosis.
