Solution

1. Preparation

• Gather tools and parts required for the repair.
• Ensure the vehicle is parked on a level surface and the engine is turned off.
• Disconnect the battery to avoid any electrical issues during the repair.

2. Inspect and Replace Engine Mounts

• Sub-steps:
  1. Raise the vehicle using a jack and secure it with jack stands.
  2. Locate the engine mounts (typically found on the front and rear of the engine).
  3. Visually inspect the mounts for cracks, tears, or excessive wear.
  4. If damaged, remove the bolts securing the engine mount to the engine and the chassis.
  5. Replace with new engine mounts, tightening bolts to manufacturer specifications (refer to service manual for torque values).

3. Check and Replace Drive Belts

• Sub-steps:
  1. Locate the drive belts and inspect for any signs of damage, such as cracks or fraying.
  2. If the belt is damaged, loosen the tensioner and remove the belt from the pulleys.
  3. Install the new belt according to the routing diagram, ensuring proper tension.

4. Inspect Suspension Components

• Sub-steps:
  1. Check all suspension components, including control arms, bushings, and struts for any signs of wear or damage.
  2. Replace any worn or damaged components as necessary, following the appropriate torque specifications for bolts.
