Well every once in awhile seems like the vacuum actuator will not positively engage the output shaft and axel shaft. Some time I get a pretty good bang when it does seem to engage or maybe disengage intermittently hard to tell sometimes. Anybody had such a problem and if so is there possibly a manual kit that could be used to replace the vacuum mechanism.

Thanks I was hoping there was a manual replacement like a PTO type cable but I will definatly look into replacement of the vacuum actuator.
