DIY wheel alignment may not be reliable.

Professional wheel alignment is a precise and complex process that requires specific tools and expertise. DIY attempts often lack the necessary accuracy and can lead to various issues.

For a proper wheel alignment, accurate measurements and adjustments are crucial. Specialized equipment like alignment machines is used to measure angles such as camber, caster, and toe precisely. In DIY settings, obtaining these precise measurements is challenging.

Also, understanding the correct adjustment values and making them accurately is difficult. Professional technicians have extensive training and experience to handle these tasks. They know how to interpret the measurements and make the appropriate adjustments to ensure optimal vehicle handling, tire wear, and fuel efficiency.

Another factor is that incorrect wheel alignment can cause uneven tire wear, affecting tire lifespan and vehicle safety. DIY efforts might not detect or correct these issues properly.

To sum up, while DIY can be attempted for some minor car maintenance tasks, wheel alignment is best left to professionals to guarantee reliable results and the safe operation of your vehicle.
