* Worn suspension components: Shocks are only part of the suspension. Worn-out ball joints, tie rod ends, control arm bushings, or other suspension components can significantly impact ride quality. These parts wear over time and cause excessive play in the suspension, leading to a bumpy ride.
* Steering linkage: Problems in the steering linkage can transmit road imperfections directly to the chassis, causing a jarring feeling.
* Leaf springs (if applicable): If your Blazer has leaf springs in the rear, they might be sagging, broken, or rusted. This will lead to a harsh ride, especially in the rear.
* Tire pressure: Incorrect tire pressure can affect ride comfort. Over-inflation leads to a stiffer, harsher ride, while under-inflation causes excessive sidewall flex and can make the ride bouncy and unstable.
* Wheel alignment: An improperly aligned vehicle will cause the tires to scrub against the road surface, resulting in a rough ride and premature tire wear.
* Body mounts: Worn or broken body mounts can allow the body to move independently from the frame, leading to increased vibration and a rougher ride.
* Frame damage: Previous accidents or rust damage to the frame can cause misalignments and impact suspension performance.
* Shock absorber quality: While you got new shocks, the quality can vary greatly. Cheap shocks may not provide adequate damping, resulting in a bouncy ride. It's also possible the wrong shocks were installed for your Blazer's configuration.
* Tire type: While you've got new tires, the *type* of tire matters. Aggressive off-road tires, for example, will give a harsher ride than all-season highway tires.
To diagnose the problem, you'll need to have a qualified mechanic inspect your Blazer's suspension system. They can identify any worn or damaged parts and recommend necessary repairs. A visual inspection might reveal some obvious problems, but a thorough professional examination is the best approach.
