• Gather necessary tools and parts.
• Ensure the vehicle is parked on a level surface and the parking brake is engaged.
• Disconnect the battery if working on electrical components.

2. Tire and Wheel Inspection

1. Remove the wheel covers or hubcaps if applicable.
2. Inspect each tire for uneven wear patterns.
3. Check tire pressures and inflate to manufacturer specifications.
4. If uneven wear is detected, consider rotating or replacing tires.
5. Reinstall wheel covers or hubcaps.

3. Alignment and Balance Check

1. Take the vehicle to a professional for wheel alignment and balance.
2. Ensure alignment specs meet manufacturer recommendations.
3. Adjust as necessary based on findings from the alignment machine.

4. Driveshaft Examination

1. Locate the driveshaft and inspect for any visible damage or corrosion.
2. Check for excessive play by trying to move the driveshaft up and down.
3. If any issues are found, remove the driveshaft using a socket set and replace it with a new or refurbished unit.

5. Suspension Component Inspection

1. Visually inspect struts, shocks, and bushings for signs of wear or damage.
2. Replace any worn components with OEM or quality aftermarket parts, following specific torque specifications for mounting bolts.
3. Use a torque wrench to tighten all bolts to the specified torque.

6. Transmission Fluid Check

1. Locate the transmission dipstick and remove it.
2. Check the fluid level and condition; it should be bright red and free of debris.
3. If fluid is low or dirty, drain and replace with manufacturer-recommended transmission fluid.
