How to Check a Car Fork
Option 1: Proceed to raise the undercarriage of the car to observe the fork. If the fork body is dented, distorted, broken or has an oil leak, it means that the fork part is damaged.
Option 2: Let the car accelerate from about 30km/h to 40km/h, then step on the brake pedal hard. If the front end of the car has a strong forward swing, it is precisely the fork part that has a problem.
Option 3: Check the quality of the fork assembly by looking at the amount of heat on the surface of the hydraulic hose. If the amount of heat on the surface of the hydraulic hose is high, the fork unit is still working well, and vice versa.

- After that, it is necessary to reassemble small details such as: small frame to hold the brake fluid in place, balance bar (twist bar).
- Finally install the wheels and lower the fleet.
