Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Ensure the engine is off, and the keys are removed from the ignition.

2. Tire Inspection and Balancing

Tools Required: Tire pressure gauge, jack, jack stands, wheel balancer.
Inspect each tire for uneven wear, cracks, or bulges.
Check and adjust tire pressure to the recommended PSI.
If tires are damaged, replace them.
If tires are in good condition, proceed to balance them using a wheel balancer.
- Remove the wheel from the hub using a lug wrench.
- Mount the wheel on the balancer and follow the machine’s instructions to add weights as needed.
- Reinstall the wheel with the correct torque specification (typically around 80-100 ft-lbs for Toyota).

3. Suspension and Driveline Inspection

Tools Required: Socket set, torque wrench, pry bar.
Inspect all suspension components (including control arms, bushings, and shocks) for wear or damage.
Replace any worn or damaged parts as necessary.
Check the driveshaft and axles for any signs of damage or misalignment.
Tighten any loose bolts to manufacturer specifications.
