Step 1: Prepare the Vehicle

• Ensure the vehicle is parked on a flat surface.

  • New Sachs shock absorbers
  • Trolley jack
  • Axle stands
  • Ratchet and socket sets (including TX20, TX25, TX40)

Step 2: Remove Interior Trim

1. Remove the Load Cover

   • Press the tabs on either side and pull the load cover out.

2. Fold the Back Seats

   • Release the tabs at the top of the seats to fold them forward.

3. Take Out the Interior Tray

   • Use a screwdriver to pry out any broken clips.
   • Lift the center part and pull out the outer sections.

4. Remove Side Panels

   • Use a ratchet screwdriver to remove:
     • One clip at the bottom
     • Two screws at the top (TX20 or TX25)
   • Carefully pop off the top trim by prying it up.
   • Unscrew and remove any stubborn clips.
   • Remove the auxiliary socket by pulling it off.

5. Access the Top Mounts

   • Remove the blanking cover to reveal the top shock mounts.
   • Take care when removing clips as they may break; consider using super glue for repairs if necessary.

Step 3: Lift the Vehicle

• Use the trolley jack to lift the car at the designated jacking points.
• Place axle stands underneath for safety.

Step 4: Remove the Old Shock Absorbers

1. Remove Wheel

   • If the wheel is stuck, use a kick or a tool to dislodge it.

2. Detach the Shock Absorber

   • Remove the lower nut (17mm) and the upper nut (usually 16mm).
   • Use lubricant to help loosen any rusted components.
   • Gently push the shock absorber out using a jack and socket to help with leverage.

Step 5: Install the New Shock Absorbers

   • Ensure the top of the new shocks is clean and ready for installation.

2. Reinstall the New Shocks

   • Position the new shock in place, pushing it through the mounting points.
   • Secure the lower and upper nuts, ensuring they are tight (use an Allen key or spanner as necessary).

Step 6: Reassemble the Vehicle

1. Reattach the Wheel

   • Clean any corrosion from the wheel hub and ensure it is free from debris.
   • Place the wheel back on and tighten the bolts.

2. Remove Axle Stands and Lower the Vehicle

   • Carefully remove the axle stands and lower the vehicle back to the ground.

3. Reinstall Interior Trim
