Which of the following may cause premature wear of suspension components?

Frequent short trips can lead to premature wear of suspension components primarily because the vehicle may not reach its optimal operating temperature during short journeys. This can prevent the proper functioning of various parts and lead to increased wear. Additionally, many stops and starts place extra stress on the suspension system as it quickly responds to changes in weight distribution and road conditions. This repeated strain can accelerate the degradation of components like shocks, struts, and bushings.

In contrast, proper vehicle alignment and balance help ensure even tire wear and consistent handling, which are essential for maintaining the integrity of suspension components. Driving on smooth roads generally reduces the impact on the suspension system, minimizing wear. Regularly checking tire pressure contributes to better handling and prevents uneven wear, further extending the lifespan of suspension parts. In essence, frequent short trips contrast sharply with practices that promote the longevity of the vehicle's suspension system.
