First off, I've searched and cant find anything. Second, this is kind of a dumb question, just has me wondeing.

I'm running a rear ARB in my 4Runner, and its the 1st ARB I've ever owned. I have the regulator set to 90psi and the locker engages and disengages GREAT!!! Love the locker!! BUT.... one thing I always remember about the ARB growing up is how much I loved that "blow off" sound they made when you disengage the locker. Mine doesn't do that.... I don't care a LOT b/c as I said, the locker functions awesome, just kinda let down b/c I was kinda excited to be able to hear it coming from my own rig and it doesn't. Anybody have any clue why its not doing it? Just mainly wanna be sure something isn't wrong and hurting something. also, FYI, I bought the locker brand new. I've been installed for about a year. Thanks
