If your 1996 Cadillac DeVille is bouncing all over the road, several things could be the cause:
* Worn-out shock absorbers: This is the most likely culprit. Worn shocks can't effectively dampen the suspension's movement, leading to excessive bouncing.
* Worn-out springs: Springs can sag or break, reducing their ability to support the car's weight and contributing to a bouncy ride.
* Damaged suspension components: Other parts of the suspension, such as ball joints, control arm bushings, or tie rod ends, could be worn or damaged, affecting the suspension's stability and causing bouncing.
* Low tire pressure: Underinflated tires can make the ride feel bouncy and unstable.
* Heavy load: If the car is carrying a significant amount of weight in the trunk or backseat, it can affect the suspension's performance.
You should have a qualified mechanic inspect your vehicle's suspension system to diagnose the problem. They can identify the specific cause of the bouncing and recommend the necessary repairs.
