I installed a new power steering rack today which obviously included opening up the lines. Is there some sort of bleeder valve to remove air bubbles that I am unaware of? I read somewhere it's a matter of moving the wheel back and forth from one side to another? Additionally, what torque specs did you follow for the copper crush washers where they meet the rack, total of 4? I just made them very tight as I know it's higher pressure, although on the motor crush washers I used I think 16ft lbs. Thank you for any input.
