I while back I replaced one of my hub locks. The one I put in was BC3Z3B396B. At the time, it was unclear if it worked with vacuum actuated locks or not, but I decided to move forward anyway.
1. Does anyone know for sure if that hub will work with vacuum actuated locks?
2. If it doesn’t support vacuum actuation, does that mean that vacuum locking would not function on either front hub even though I only replaced one of them?
What on the dial free/lock or does it have auto/lock on it? If its free/lock its a manual hub and you will have to get out to engage that hub every time and then turn it back to free when your finished. Now on to the auto function still working I'm not sure but I think it wont work becase the manual hub will let air into the system and wont hold vacuum for the system to work correctly
