What can cause of pulling left after a steering shaft changed?

Pulling to the left after a steering shaft change can be caused by misalignment of the wheels, improper installation of the steering components, or worn suspension parts. If the steering angle sensor is not calibrated correctly, it can also lead to pulling. Additionally, uneven tire pressure or tire wear can contribute to the issue. It's advisable to have a professional inspect the alignment and steering system to identify the exact cause.
