⚠️ Safety Warnings

Important safety information - read before proceeding

•Always use jack stands when working underneath the vehicle.
•Ensure the vehicle is on a flat surface before lifting.

Symptoms

•Vehicle swaying or rocking side to side while driving
•Diminished handling stability, especially during turns
•Uneven tire wear
•Increased body roll during cornering
•Steering wheel vibrations at higher speeds

Diagnostic Steps

1
Inspect the tire pressure on all four tires to ensure they are within manufacturer specifications.
2
Perform a visual inspection of the suspension components, including shocks/struts, control arms, and bushings for any signs of wear or damage.
3
Check the alignment settings using an alignment machine to determine if the vehicle is out of specification.
4
Examine the tires for uneven wear patterns, bulges, or defects.
5
Test drive the vehicle to replicate the swaying sensation and note under what conditions it occurs (e.g., at speed, during turns).

Solution

Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.

2. Tire Pressure Adjustment

Use a tire pressure gauge to check the pressure of each tire.
Inflate or deflate tires to the recommended pressure as per the owner's manual.

3. Suspension Component Replacement

Tools Required: Socket set, torque wrench, jack stands, wheel chocks
Sub-steps:
1. Lift the vehicle using a jack and secure it with jack stands.
2. Remove the front or rear wheels to access the suspension components.
3. If any shocks or struts are worn, remove them by unbolting the upper and lower mounts.
4. Replace with new shocks or struts, ensuring they are torqued to manufacturer specifications.
5. Inspect and replace any damaged bushings or control arms as needed.

4. Wheel Alignment

Tools Required: Alignment machine
Sub-steps:
1. After replacing components, lower the vehicle back to the ground.
2. Use an alignment machine to check and adjust the wheel alignment to manufacturer specifications.
3. Make adjustments to the camber, caster, and toe angles as necessary.

5. Final Inspection

Reinstall the wheels and torque them to the specified value.
Lower the vehicle and perform a final visual inspection of the suspension.
