What is the major drawback of a MacPherson strut suspension?

The major drawback of a MacPherson strut suspension is that it reduces the ability to adjust camber and caster angles. This suspension design integrates the strut and spring into a single unit, which simplifies construction and reduces weight compared to more complex suspension systems. However, this design can limit the adjustability of alignment angles, making it more difficult to fine-tune the vehicle’s handling characteristics.

In vehicles equipped with MacPherson strut suspension, any changes in alignment often require replacing components rather than making straightforward adjustments. This limitation is particularly significant in performance applications where precise alignment is crucial for optimal handling and tire performance.

Understanding this characteristic is critical for technicians who may need to address alignment issues, as the limitations of the MacPherson strut design can impact the choices they make in vehicle service and repair.
