Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is on a flat surface and secure the vehicle with wheel chocks.
Disconnect the battery to avoid any electrical issues.

2. Remove the Old Shocks

Tools Required: Socket set, wrench set, torque wrench, jack, jack stands.
Raise the vehicle using a jack and secure it on jack stands.
Remove the wheel to access the shock absorber.
Unbolt the shock from the upper mount and lower mount using the appropriate socket and wrench.
Carefully detach the shock absorber from the suspension assembly.

3. Install New Shocks

Tools Required: Same as above.
Position the new shock absorber where the old one was removed.
Attach the shock absorber to the lower mount first, then to the upper mount.
Torque the bolts to the manufacturer’s specifications (typically around 30-40 ft-lbs, but check the specific torque values for your model).
Reinstall the wheel and lower the vehicle back to the ground.

4. Final Inspection

Check all bolts to ensure they are secure.
Ensure that the suspension is aligned properly and that there are no visible issues.
Perform a bounce test again to confirm proper operation.
