2. Inspect for uneven wear; replace tires if excessively worn or damaged.
3. Rotate tires if necessary, following manufacturer recommendations.
Tools Required: Tire pressure gauge, jack, jack stands, lug wrench
Safety Warnings: Ensure vehicle is on a flat surface and secured before lifting.

2. Wheel Balancing and Alignment

Sub-steps:
1. Remove the wheels using a lug wrench.
2. Mount the wheels on a wheel balancer and adjust as necessary.
3. Conduct a four-wheel alignment using an alignment machine and adjust according to specifications.
Tools Required: Wheel balancer, alignment machine, torque wrench
Safety Warnings: Keep hands clear of moving parts during balancing.

3. Suspension Component Inspection

Sub-steps:
1. Visually inspect all suspension components for signs of wear or damage.
2. Replace any worn bushings, struts, or other components as needed.
3. Reassemble any disassembled parts and ensure all fasteners are properly torqued.
Tools Required: Socket set, torque wrench, pry bar
Safety Warnings: Use appropriate safety gear and ensure vehicle is securely supported.

4. Drivetrain Inspection

Sub-steps:
1. Inspect the driveshafts for any visible damage or play.
2. Check motor mounts for wear; replace if cracked or sagging.
3. Test drive the vehicle again to verify if vibrations persist.
Tools Required: Socket set, pry bar, inspection mirror
Safety Warnings: Ensure vehicle is off and cool before inspecting drivetrain components.
