What can cause a vehicle's suspension to sag?

A vehicle's suspension can sag due to several factors, primarily involving worn springs, heavy loads, or damaged suspension components. Over time, the springs in a vehicle are subjected to repeated stress and can lose their ability to support the vehicle’s weight effectively when they become worn. This can lead to a noticeable sagging of the suspension.

In addition, carrying excessively heavy loads can exceed the designed capacity of the springs, leading to sagging. It is important to note that the suspension system must be able to keep the vehicle level regardless of load conditions, and when this system is compromised, it can result in a decrease in ride height.

Furthermore, damaged suspension components, such as struts or shocks, can also affect the overall integrity of the suspension. If these components are not functioning properly, they may not be able to maintain the correct vehicle height, contributing to sagging.

High tire pressure, improper wheel alignment, and frequent oil changes do not directly cause suspension sagging. High tire pressure might create a firmer ride but would not contribute to sagging. Similarly, improper wheel alignment affects tire wear and handling but does not influence the height of the suspension. Frequent oil changes are unrelated to suspension performance. Thus, the focus of sagging issues should
