Over time, the front fork shock on a scooter takes an aggregate beating that tends to reduce its ability to offer a smooth ride. Replacing them with new dampners not only protects the scooter's frame, but also makes your own riding experience more enjoyable. The steps below assume the shock is already separated from the scooter.

Place the shock assembly in a vice clamp to keep it stable, with the unit standing vertically. Use two crescent wrenches to remove the securing nut at the top of the assembly. Loosen the nut and remove it.
Take the top spring cap off the unit. Pull the shock spring up and off the assembly. Remove the rubber buffers from the dampener rod that protect it from hitting the top cap.
Replace the old dampener with a new unit. Unpack the unit and expand the dampener (they ship compressed). Slip the shock spring onto the dampener, inserting the dampener body into the inside of the spring.
Insert the dampener rod sticking out of the top of the assembly through the centre of the previously removed rubber buffer. Attach the top spring cap and twist it on. Reinsert the new dampener as assembled so far into the vice clamp again. Twist the spring cap onto the dampener rod threads as far as it will go.
Keep the spring cap stable while attaching and threading the securing nut. Tighten the securing nut onto the rod threads until it is tight against the spring cap previously installed. Take the complete front shock and reinstall it in the scooter.
Tips and warnings
- Use nut-penetrating lubricant such as WD-40 to get the securing nut to twist if it is on too tight.
- Do not loosen the spring cap and securing nut at the same time. The force of the compressed shock spring could pop the securing nut off hard enough to cause injury.
