It's been doing this ever since after the 1st week of install and still continues. I brought it to both EAS and Supremepower to figure out whats up, but they were only able to provide temporary fix. So could this be a defective rear section that I got here? If it is, do you guys think I could still get it replaced?  |
I had a similar problem when i first installed my Eisenmann...found out that the actuator spring wasn't putting enough pressure on the valve so it was vibrating under load. What I ended up doing was taking out the spring and bended it outwards a bit using a set of pliers. Haven't had any noise since. |
This is exactly what EAS did for my unit, but the noise came back after I had gintani dp installed. Supreme power checked it twice to figure out what it is but in the end they jus concluded that one of the valves is loose and flaps under pressure.
