why does my Toyota Camry XV40 (2007-2011) make a knocking noise when driving

Solution

1. Preparation

• Gather tools and parts needed for the repair.
• Park the vehicle on a level surface, engage the parking brake, and if necessary, lift the vehicle using a jack and secure it with jack stands.
• Tools required: Socket set, torque wrench, pry bar, and safety gloves.

2. Inspect and Replace Engine Mounts

• Sub-steps:
  1. Remove the engine cover if applicable.
  2. Disconnect the battery to avoid electrical issues.
  3. Use a jack to support the engine slightly.
  4. Remove the bolts securing the engine mount to the engine and the chassis.
  5. Remove the old engine mount and replace it with a new mount.
  6. Torque the mounting bolts to the manufacturer's specifications (typically around 30 ft-lbs).

3. Check and Repair Suspension Components

• Sub-steps:
  1. Inspect struts and shocks visually for leaks or damage.
  2. If damaged, remove the old struts/shocks using a socket set.
  3. Install new struts/shocks and torque bolts to specifications.
  4. Inspect control arms and bushings for wear; replace if necessary.

4. Secure Exhaust System

• Sub-steps:
  1. Inspect the exhaust hangers and brackets for rust or damage.
  2. Tighten any loose bolts or replace damaged hangers.
  3. Ensure the exhaust system is properly aligned and secured.
