A vehicle pulls slightly to the left at all times. The cause could be:

The key idea is that steering geometry being unequal from side to side can pull a car in one direction even when you’re driving straight. Caster is the angle of the steering axis when viewed from the side, and it helps with straight‑line stability and self‑centering of the wheels. If the left and right wheels don’t have the same caster, the steering forces aren’t balanced. The wheel with less caster is more easily deflected by road irregularities and road load, so the vehicle tends to drift toward that side. That’s why a persistent pull to the left can be caused by unevenly adjusted caster. Other issues like unequal tire pressures, a sticking brake caliper, or misaligned toe can also cause pulling, but they produce effects tied more to tire contact, braking, or toe alignment rather than a consistent straight-line pull due to unequal steering-axis tilt. To fix it, check and bring caster angles on both sides into specification through proper front-end alignment and inspect suspension components for wear or damage.
