Solution

1. Preparation

• Gather required tools and parts.
• Ensure the vehicle is parked on a level surface and the parking brake is engaged.
• Disconnect the battery to ensure safety while working on electrical components.

2. Inspect Rear Suspension

• Sub-steps:
  • Raise the rear of the vehicle using a jack and secure it with jack stands.
  • Visually inspect the rear springs, control arms, and bushings for signs of wear or damage.
  • Use a pry bar to check for excessive play in the suspension components.
