Tire Pressure:
Uneven tire pressure can cause a car to pull to one side. Check the tire pressure of all four tires and adjust them to the recommended levels indicated in the vehicle's owner's manual.
Wheel Alignment:
Wheel alignment refers to the angles at which the wheels are set. If the alignment is off, it can cause the car to pull to one side. Wheel alignment should be checked and adjusted if necessary by a qualified mechanic.
Suspension Components:
Worn or damaged suspension components, such as control arms, tie rods, or ball joints, can cause the car to pull to one side. These components should be inspected and replaced if necessary.
Brakes:
Uneven wear or malfunctioning brakes can cause the car to pull to one side. Check the brake pads and rotors and ensure they are in good condition.
Driveline Components:
Issues with the driveline components, such as a worn or damaged driveshaft, universal joints, or differential, can also cause the car to pull to one side.
If you have checked all of these potential causes and your car is still pulling to the left, it is recommended to take it to a qualified mechanic for further diagnosis and repair.
