1. Shock absorbers can leak for various reasons. If leakage occurs soon after installation, it's often due to incorrect tool use or improper oil seal orientation during installation. Therefore, it's important to use the correct tools and follow the correct installation order to ensure smooth operation: oil seal > inner tube > snap ring > dust seal.

Oil seals and dust seals are made of rubber. Even with low mileage, rubber can harden over time, making these parts consumable. As with tires, we recommend replacing these parts regardless of mileage or age, and we don't recommend reusing them.
