A vehicle has worn jounce bumpers. Which of the following could be the cause?

Worn jounce bumpers are often a result of ineffective shock absorbers, which can lead to excessive bottoming out of the suspension. When shocks are leaking, they lose their ability to dampen the energy from bumps and impacts on the road, which can cause the vehicle's suspension to travel further than it normally would. This increased travel can result in the jounce bumpers being compressed more than intended, leading to accelerated wear.

The condition of the jounce bumper is directly related to the functioning of the shock absorbers because they work together to control the ride and handling of the vehicle. If the shocks are unable to perform adequately due to leakage, this can lead to a harsher ride and can cause the jounce bumpers to wear out more quickly from frequent contact with the suspension limits. Thus, the situation of worn jounce bumpers being linked to leaking shocks is a sound understanding of how the suspension system operates.
