* Worn-out shock absorbers (struts): This is the most common cause. Shocks dampen the oscillations of the springs, and if they're worn, they won't control the rebound, leading to excessive bouncing. They leak fluid and become less effective over time.
* Worn-out struts: Similar to shocks, struts are a combined spring and shock absorber unit. Worn struts will cause bouncing.
* Broken or worn suspension springs: The springs support the weight of the car. If a spring is broken or weakened, it won't provide proper support, leading to uneven bouncing or sagging on one side.
* Worn-out or damaged bushings: Bushings are rubber components that connect various suspension parts. Worn bushings allow excessive movement and play in the suspension, leading to instability and bouncing.
* Worn ball joints: These connect the control arms to the steering knuckle and allow for steering and suspension movement. Worn ball joints can cause instability and bouncing, especially noticeable when turning.
* Worn tie rod ends: Similar to ball joints, these connect the steering rack to the wheels. Worn tie rod ends can lead to excessive play and bouncing, particularly noticeable during steering maneuvers.
* Problems with the sway bar and its bushings/links: The sway bar helps control body roll in turns, but if it's damaged or its connecting components are worn, it can contribute to bouncing.
* Wheel alignment issues: While less likely to cause *bouncing* directly, significant misalignment can make the car feel unstable and contribute to a sensation of bouncing.
To diagnose the problem:
1. Visual inspection: Carefully examine your suspension components for any obvious damage, leaks (in shocks/struts), or broken parts. Look for rust, cracks, or excessive wear.
2. Bounce test: Gently push down on each corner of the car. If it bounces excessively or continues to bounce for a long time after you release it, it indicates worn shocks or struts.
3. Professional inspection: The best approach is to take your LeSabre to a qualified mechanic. They can perform a thorough inspection, diagnose the problem accurately, and recommend the necessary repairs.
Ignoring a bouncing suspension is dangerous. It can lead to loss of control, especially at higher speeds, and increased wear on other components. Get it checked out as soon as possible.
