my Toyota Corolla E170 (2013-2019) makes a rattling noise when driving over rough roads

Solution

1. Preparation

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

2. Inspect Suspension Components

• Tools Required: Socket set, torque wrench, pry bar
• Remove the wheels to gain access to the suspension components.
• Inspect the shock absorbers/struts for leaks or physical damage; replace if necessary.
• Check sway bar links for play; replace any worn or broken links.

3. Tighten Loose Components

• Tools Required: Socket set, torque wrench
• Use a torque wrench to ensure all bolts and nuts on the suspension components are tightened to manufacturer specifications.
• Inspect and tighten any loose brackets or fasteners found during the visual inspection.

4. Replace Worn Bushings

• Tools Required: Jack stands, socket set, bushing tool kit
• Remove the affected suspension component (e.g., sway bar or control arm) as needed to access the bushings.
• Use a bushing tool kit to press out the old bushings and press in new ones.
• Reinstall the suspension component and torque to specifications.
