my Toyota Corolla E170 (2013-2019) makes a clunking noise when going over bumps what's wrong

Solution

1. Preparation

• Tools Required: Jack, jack stands, socket set, torque wrench, pry bar, flashlight
• Lift the vehicle using a jack and secure it with jack stands.
• Wear safety goggles and gloves to protect yourself from debris.

2. Inspect and Replace Worn Suspension Components

• Shock Absorbers/Struts Replacement:

  1. Remove the wheel to access the suspension components.
  2. Disconnect the shock absorber from the lower control arm and the upper mount.
  3. Remove the old shock absorber/strut.
  4. Install the new shock absorber/strut in reverse order, ensuring to torque the upper mount and lower bolts to manufacturer specifications (typically around 30-35 ft-lbs).

• Sway Bar Link Replacement:

  1. Locate the sway bar links and inspect for wear.
  2. Use a socket to remove the bolts securing the sway bar link to the sway bar and control arm.
  3. Install the new sway bar link, ensuring it is torqued to the specified value (usually around 15-20 ft-lbs).

3. Tighten or Replace Loose Fasteners

• Check all suspension-related bolts and fasteners for tightness.
• Replace any damaged bolts with OEM specifications and torque to the recommended values.
