2. Diagnostic Steps

Step 1: Visual Inspection

• Objective: Identify any obvious damage or wear.
• Procedure:
  • Park the vehicle on a level surface.
  • Inspect the rear suspension components, including control arms, bushings, shocks/struts, and springs.
  • Look for cracks, rust, or any signs of fluid leakage from the shocks.

Step 2: Check for Play in Suspension Components

• Objective: Determine if any components are worn or loose.
• Procedure:
  • Lift the rear of the vehicle using a floor jack and secure it with jack stands.
  • Grasp the wheel at the 3 o'clock and 9 o'clock positions and wiggle it to check for play.
  • Repeat at the 12 o'clock and 6 o'clock positions.

Step 3: Inspect Shock Absorbers

• Objective: Ensure the shocks are functioning properly.
• Procedure:
  • Push down on the rear of the vehicle and release; the car should rebound and return to rest without excessive bouncing.
  • Check for any signs of oil leakage around the shocks.

Step 4: Alignment Check

• Objective: Ensure the rear wheels are properly aligned.
• Procedure:
  • Take the vehicle to a professional alignment shop for precise measurements.

3. Tools Required

• Floor jack and jack stands
• Torque wrench
• Socket set (including deep sockets)
• Ratchet and extensions
• Pry bar
• Screwdrivers (flathead and Phillips)
• Replacement parts (shocks, bushings, control arms, etc., as necessary)
• Alignment tools (if performing DIY)
• Safety goggles and gloves

4. Repair Instructions

A. Replacing Shock Absorbers

1. Safety First:

   • Park the vehicle on a flat surface and engage the parking brake.
   • Lift the rear of the vehicle with a floor jack and secure it with jack stands.

2. Remove the Wheel:

   • Using a lug wrench, loosen and remove the lug nuts.
   • Take off the rear wheel to access the shock absorber.

3. Detach the Shock Absorber:

   • Locate the upper and lower mounting bolts of the shock.
   • Use a socket set to remove the lower bolt first (may require a pry bar for leverage).
   • Remove the upper bolt, then carefully take out the shock absorber.

4. Install New Shock Absorber:

   • Position the new shock absorber in place.
   • Start by tightening the upper bolt first, followed by the lower bolt. Use a torque wrench to tighten to the manufacturer’s specifications.

5. Reinstall the Wheel:

   • Place the wheel back on and hand-tighten the lug nuts.
   • Lower the vehicle and then use a torque wrench to properly tighten the lug nuts in a crisscross pattern.

6. Repeat for Other Side:

   • If replacing both shocks, repeat the steps on the opposite side.

B. Replacing Control Arms or Bushings

1. Follow Steps A1 and A2 to Lift and Remove the Wheel.

2. Remove the Control Arm:

   • Use a socket to remove the bolts securing the control arm to the chassis and the rear axle.
   • If bushings are worn, use a pry bar to remove the old bushings before installing new ones.

3. Install New Control Arm or Bushings:

   • Position the new control arm and secure it with the bolts.
   • Torque to manufacturer specifications.

4. Reinstall the Wheel and Lower the Vehicle.

5. Repeat as Necessary for Other Suspension Components.

C. Alignment

• After any suspension repairs, it is crucial to have the alignment checked and adjusted at a professional shop.
