Incorrect alignment settings can adversely affect handling. Tolerable camber, caster and toe settings can be verified by a print-out from your alignment/Tyre shop or vehicle dealer. Check for unequal tyre pressure, brake system.
If the Tyres are evenly worn, the alignment is in order and there is still a pull, the front Tyres should be criss-crossed (as long as they are not a directional tread design) to see if the pull changes directions.
This should be performed by authorised dealer.
Others reason for pulling may be:
- Front tyre OD variation
- Pulling may be due to defective suspension system
- Jam of Braking shoes
- Unequal braking forces at different wheel (left side vs. right side)
- Different tyre pattern / different worn out tyres / different size or aspect ratio put on left side vs. right side
