Q: How to inspect the CV Boot of a Chevrolet Cobalt,HHR and Saturn ION?
A: With the vehicle stopped and the front wheels pointed straight ahead, rock the steering wheel gently back and forth to check for excessive freeplay. Excessive freeplay may indicate worn front wheel bearings, steering shaft universal joint, lower arm balljoint, or a broken or improperly adjusted steering gear. Other symptoms such as excessive body movement over rough roads, swaying around corners, and binding when turning the steering wheel may indicate faulty steering or suspension components. Check the shock absorbers by pushing down and releasing the vehicle at each corner. If the vehicle does not come back to a level position within one or two bounces, the shocks/struts are worn and need to be replaced. Listen for squeaks and noises from the suspension components while bouncing the vehicle. Check the struts and shock absorbers for evidence of fluid leakage. A light film of fluid is normal, but if leakage is noted, replace the struts/shocks as a set. Ensure that the struts and shocks are securely mounted and undamaged, and check the upper mounts for damage and wear. Raise the vehicle with a floor jack and support it securely on jackstands. Check the tires for irregular wear patterns and proper inflation. Inspect the universal joint between the steering shaft and the steering gear housing, as well as the steering gear housing for lubricant leakage. Check the steering linkage for looseness or damage, and inspect the tie-rod ends for excessive play. Look for loose bolts, broken or disconnected parts, and deteriorated rubber bushings on all suspension and steering components. Check the steering components for free movement, chafing, and binding while an assistant turns the steering wheel. Check the balljoints for wear by trying to move each control arm up and down with a prybar. Replace any balljoint with play. Inspect the balljoint boots for damage and leaking grease, and replace them if necessary. At the rear of the vehicle, inspect the suspension arm bushings for deterioration. Lastly, inspect the CV boots for tears, cracks, and loose clamps. Wash the boots with soap and water to prevent premature deterioration. The outer CV boot should be inspected regularly due to constant pivoting. Replace any boots with cracks or leaking lubricant.
