If a vehicle sits lower on the left rear than on the right rear, what could be the most likely cause?

When a vehicle exhibits a lower stance on one side, such as the left rear being lower than the right rear, it is often indicative of an issue with the suspension components that support that side. A weak left rear spring is a likely cause because springs are essential for holding the vehicle's weight and maintaining ride height. Over time, springs can lose their strength due to fatigue or wear, leading to sagging on one side.

In this specific case, if the left rear spring is weak, it will not provide adequate support for the vehicle's weight, resulting in that corner sitting lower compared to the right rear, which is likely supported by a functioning spring. This condition can also affect the overall handling and ride quality of the vehicle, potentially leading to uneven tire wear and alignment issues.

The other choices represent potential causes that could impact ride height, but they do not directly indicate the same level of immediate spring-related support as a weak spring does. For example, while a weak shock may lead to changes in ride performance, it typically does not result in a noticeable difference in ride height when compared to the other side. Similarly, if only one shock was replaced, it might cause handling differences but wouldn’t create a significant height discrepancy on just that side. W
