I'm having the same issue. There are two plugs that can plug into the motor, but only 1 motor. Anyway each plug has two wires and I measured 12v from each wire. I ran the motor off of the battery and the fluid sprays fine any ideas?
It's not that cheap axles fail under hard driving. They just plain suck. One of the Duralast axles I had made clicking noises even when up to speed and it was brand spanking new.
My experience with aftermarket axles has been hit or miss by a lot. EMPI and FEQ have been pretty good so far. Duralast was pure garbage. I went throuth 3 within a few months and the fourth one wasn't even that great.
