Save money in repair bills, and ensure the safety of your passengers by checking and replacing your Kia shocks regularly. Tired shocks will prematurely wear out your tires and increase the odds of aquaplaning in the rain. If neglected, your shocks will then have a detrimental effect on your suspension parts, such as the ball joints, steering linkage, and springs. In particular, when the shock absorbers get worn, they allow the wheels to bounce, which results in poor tire-to-road contact, vibrations, reduced braking performance and increased noise. It is recommended that you check your Kia shocks every 12,000 miles or so. At that point, look for signs of wear and tear. Does the car roll or sway when you turn? Does the front end dive when you brake, or the read end squat when you accelerate? Sometimes you might feel bouncing or sliding on winding roads, or feel thumps when you strike bumps. Look for signs of oil seepage where your shock absorbers are located. Test the shocks by bouncing the car up and down. The car should stop bouncing as soon as you stop moving your hand against the bumper. Prompt attention to your Kia shocks - and replacement at these signs of deterioration - will preserve your car's smooth ride.
