My right side fork keeps leaking. I just had the seals replaced and they still keep leaking. A puddle in the back of my truck, a puddle in the garage, etc... I think i need new shims but cant afford them and another break down/rebuild right now. QUESTION: Ive heard that i can add fork oil through the pressure release valve. Is that true? Is there anyway to determine how much I need to add or any way to check the final level after adding?
