How to Diagnose and Fix Common Car Suspension Problems

Driving should be a smooth and comfortable experience, but suspension problems can turn it into a jarring ride. At Advanced Auto, we recognize the value of a properly maintained suspension system for your car’s comfort and safety. We’ll now walk you through identifying and resolving common suspension problems in your car.

Understanding the Suspension System

To provide stability and comfort, your car’s suspension system maximizes the contact between the tires and the road. It consists of multiple parts:

• Springs: Take up the energy from uneven surfaces.
• Struts and Shocks: Lessen the force of the springs and stop too much bouncing.
• Control Arms: Allow up-and-down movement and connect the wheels to the vehicle’s structure.
• Bushings: Reduce rubbing between the frame and control arms.
• Sway Bars: Contribute to stability when a turn is made.

It is essential to understand these elements to properly diagnose and treat suspension issues.

Common Suspension Problems and Their Symptoms

1. Uneven Tire Wear

Symptom: You observe that one side of your tires has greater wear than the other.

Potential Reasons: Uneven tire wear might be caused by misaligned wheels, worn-out shocks or struts, or defective control arms.

Solution: Have your wheels’ alignment checked and adjusted if needed. Examine and replace any worn-out control arms, struts, or shocks.

2. Vehicle Pulling to One Side

Symptom: When traveling straight ahead, your car pulls to one side.

Possible Causes: Worn-out suspension parts, uneven tire pressure, or misaligned wheels could cause this.

Solution: Check and adjust your tire pressure and wheel alignment. Reinstall any worn suspension components.

3. Excessive Bouncing

Symptom: After striking a pothole or bump, your car keeps bouncing.

Potential Reasons: The most frequent reason for excessive bouncing is worn-out shocks or struts.

Solution: Check for damage or leaks in the shocks and struts and replace them as needed.

4. Noise While Driving Over Bumps

Symptom: When driving over bumps, you hear clunking or squeaking noises.

Potential Reasons: These noises may result from worn-out control arms, ball joints, or bushings.

Solution: Examine and replace worn-out control arms, ball joints, or bushings.

5. Steering Problems

Symptom: You find it difficult to steer, or the steering wheel has a lot of play.

Potential Causes: Ball joints, worn-out tie rods, or problems with the steering rack may cause this.

Solution: Check and replace damaged ball joints and tie rods or address problems with the steering rack.

Diagnosing Suspension Problems

Proper diagnosis is key to fixing car suspension problems effectively. Here’s a step-by-step guide to help you diagnose common issues:

1. Visual Inspection

Start with a thorough visual inspection of the suspension components. Look for:

• Leaks in shocks or struts.
• Worn-out or damaged bushings.
• Bent or damaged control arms.
• Uneven tire wear.

 

2. Bounce Test

Apply pressure on and release from each corner of the car to conduct a bounce test. The shocks or struts may be worn out if the car bounces more than once or twice.

3. Check Tire Pressure

Make sure the proper pressure is applied to all tires. Suspension issues can appear as uneven tire pressure.

4. Wheel Alignment Check

If your car pulls to one side or the steering seems off, get the wheel alignment examined by a professional.

5. Test Drive

Take your car for a test drive on uneven terrain and level roads. Look for any odd vibrations, noises, or handling issues.

Fixing Common Suspension Problems

It’s time to repair the problem once you’ve identified it. The following are some typical solutions for suspension issues:

1. Replacing Shocks and Struts

Tools Required: Torque wrench, socket set, wrench set, jack, and jack stands.

Steps:

1. Using a jack, raise the car, then use jack stands to keep it in place.
2. To gain access to the shocks or struts, remove the wheels.
3. Unbolt the shock absorbers or struts from the vehicle’s frame and control arms.
4. Install the new shocks or struts and tighten the fasteners according to the manufacturer’s instructions.
5. After reinstalling the wheels, lower the car.

2. Replacing Control Arm Bushings

Tools Needed: socket set, wrench set, bushing press, and jack stands.

Steps:

1. Raise the vehicle and use jack stands to secure it.
2. Remove the wheels to get to the control arms.
3. Unbolt the control arms’ bolts from the steering knuckle and the car’s structure.
4. The old bushings can be taken out using a bushing press.
5. Reattach the control arms after pressing the new bushings into position.
6. Lower the car after reinstalling the wheels.

3. Wheel Alignment

Tools Needed: Professional alignment tools.

Steps:

1. Take your car to a qualified mechanic who has alignment equipment.
2. The mechanic will adjust the wheel angles to meet the manufacturer’s requirements.
3. Make sure the car drives straight and has responsive steering by giving it a test drive.

4. Replacing Tie Rods and Ball Joints

Tools Needed: Jack, jack stands, wrench set, socket set, ball joint separator.

Steps:

1. Lift the vehicle and secure it with jack stands.
2. Remove the wheels to access the tie rods and ball joints.
3. Unbolt the tie rods from the steering knuckle and the steering rack.
4. Use a ball joint separator to remove the ball joints.
5. Install the new tie rods and ball joints, and tighten the bolts to the manufacturer’s specifications.
6. Reinstall the wheels and lower the vehicle.

Preventive Maintenance Tips

The lifespan of your suspension components can be increased, and suspension issues can be avoided with routine maintenance:

• Examine Regularly: Visually examine the suspension’s parts regularly.
• Verify Tire Pressure: Maintain the correct tire pressure on your tires.
• Tire Rotation: To guarantee even wear, rotate your tires on a regular basis.
• Alignment Verifications: Every year or whenever you notice handling problems, you should have your wheel alignment checked.
• Replace Worn-Out Parts: To stop more damage, replace worn-out suspension parts immediately.
