Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Allow the vehicle to cool down if it was recently driven.

2. Lift the Vehicle

Using a jack, lift the vehicle and secure it with jack stands.
Remove the wheels for easier access to the shocks (if necessary).

3. Remove Old Shocks

Locate the shock absorber and remove any protective covers if present.
Use a socket set to remove the bolts securing the shock to the upper mount.
Remove the lower bolt using a wrench; if necessary, use a breaker bar for stubborn bolts.
Carefully take out the shock absorber from its mounting position.

4. Install New Shocks

Compare the new shock with the old one to ensure they are identical in size and specifications.
Position the new shock absorber into place and secure it with the lower bolt first, tightening to manufacturer specifications (usually around 30-50 lb-ft, check specific values).
Attach the upper mount and tighten the bolts to the specified torque.
Reinstall any protective covers.

5. Reassemble and Test

Reattach the wheels and lower the vehicle back to the ground.
Conduct a bounce test to verify proper installation.
Take the vehicle for a test drive to ensure stability and comfort.
