Why do you need a front end alignment when replacing struts?

A front end alignment is necessary when replacing struts because new struts can alter the vehicle's suspension geometry, affecting wheel alignment angles. Proper alignment ensures that the wheels are positioned correctly relative to each other and the road, which helps prevent uneven tire wear, improves handling, and enhances overall vehicle safety. Additionally, a misaligned vehicle can lead to further suspension issues and reduced ride quality, making alignment a crucial step after strut replacement.
