1. Structure and operating principle of shock absorber rod (fork rod)
The shock absorber rod (fork rod) is structured like an iron rod with a piston and hydraulic oil, in addition to a rubber seal to prevent oil from spilling out. The rod body is often chrome-plated to prevent rust and scratches.
The rod is the part that will bear the main force when the wheel touches the road surface. The pressure in the rod depends on the shock absorber oil and air. When going through a bumpy section, the spring will push the elastic rod back to its original state. Therefore, the shock absorber rod is a moving part, not a fixed part.
Classification of front and rear shock absorber rods
Front rod: It is structured like an iron tube, with a screw at the end. Some car models have different core and screw structures on the front rod. Usually these details of the front rod are quite small and difficult to identify.
Ty trước có nhiều loại với chiều dài tương ứng khác nhau. Ví dụ ty phuộc trước của xe Winner là 30 cm, còn Exicter là 26 cm, …
Rear rod: Stands out with a round rod on the head and a small screw at the end of the rod, quite different from the front rod.
There are 2 types of rear rods: 8 and 10. To choose the rear rod to match the vehicle, you need to pay attention to the length and the ear at the rod body. For example, for type 8 rod, Wave Jusi has no ear and a short body, Wave Alpha has no ear and a long body, Dream has ear but a short body, etc.

2. Abnormal signs of the vehicle that need to check the shock absorber rod and how to fix it
Weak or creaking shock absorbers: Sometimes strong impacts or vibrations can also cause the hydraulic rod to bend, causing the shock absorber to make a creaking sound when running.
Oil leak: The vehicle makes a rattling sound, the end of the shock absorber has rusty oil on it, which is a sign that the vehicle has a loose seal and hydraulic rod oil is leaking.
Steering wheel deviation: A vehicle with a skewed steering wheel is considered to be seriously damaged. One of the most likely causes is that the shock absorber rod is deformed or broken.
Rod travel length: When carrying a load exceeding the specified parameters, the rod will travel almost to the end of the travel length, causing great pressure, increasing the possibility of the rod being scratched and leaking oil.
3. How to fix a problem with the shock absorber rod
Oil leaking rod: Fix by replacing the new seal and pumping oil. Vehicle owners should take the vehicle to a reputable repair shop so that the mechanic can adjust the correct amount of oil needed.
Bent rod: Straighten the hydraulic rod with a specialized tool. In case the rod is severely bent or broken, it must be replaced. During the mechanic’s handling process, the vehicle owner should stand and observe to avoid having the genuine shock absorber rod swapped with fake or low-quality imitation goods.
Note how to check the original shock absorber rod according to the vehicle:
The genuine rod has a shiny, scratch-free metal body. When pulling out and pressing in, there is no oil film on the rod body, the braking force when pressing and pulling is good (for the rear shock absorber rod).
