Inspect Strut: Check for oil leaks, damage, and overall condition. If damaged, replace the strut.
Install New Strut: If replacing, line up the new strut with the mount and secure it in place.
Torque Specifications: Tighten bolts to the manufacturer’s specified torque ratings (refer to service manual for values).
Reattach Brake Line: Secure the brake line back to its original position.

4. Reassemble Vehicle

Reattach Wheel: Put the wheel back on and hand-tighten the lug nuts.
Lower Vehicle: Remove the jack stands and lower the vehicle back to the ground.
Torque Lug Nuts: Once on the ground, fully tighten the lug nuts to the specified torque.
