    Q:
    How should one check the Shock Absorbers for the 2007 Chevrolet Trailblazer? Posted by Dontay S.
    A:
    Park the vehicle on level ground, turn off the engine, and set the parking brake. Then, check tire pressures and push down on one corner of the vehicle. Release it and observe if it stops moving and returns to a level position within one or two bounces. If it continues to move or fails to return, the shock absorber may be worn or weak.
