Solution

1. Preparation

• Gather tools: socket set, jack and jack stands, torque wrench, tire pressure gauge.
• Park the vehicle on a flat surface and engage the parking brake.
• Allow the vehicle to cool if it has been recently driven.

2. Inspect Suspension Components

• Step 1: Use a jack to lift the vehicle and support it with jack stands.
• Step 2: Visually inspect all suspension components for signs of wear, cracks, or leaks. Focus on struts, shocks, and bushings.
• Step 3: If any components are damaged, replace them with OEM or quality aftermarket parts.

3. Check Wheel Alignment and Tires

• Step 1: Measure tire pressure and inflate to the manufacturer’s specifications if necessary.
• Step 2: Inspect tires for uneven wear or damage. Replace any tires that are excessively worn or damaged.
• Step 3: If alignment is off, take the vehicle to a professional alignment shop for correction.

4. Tighten Loose Components

• Step 1: Check all suspension bolts and nuts for proper torque using a torque wrench.
• Step 2: Tighten any loose components according to the manufacturer’s specifications found in the service manual.
