Re: Moaning, groaning, angry hyroboost power steering
You should be able to cycle it lock to lock to work the air out, sometimes it takes a little bit. Make sure you aren’t low on fluid as the hydraboost unit takes quite a bit more fluid than a standard unit. I ran my old suburban out of fluid when trying to purge the air out after a pump change. it’s relatively easy to do once you start turning the wheels if your not adding fluid in to displace the air your working out. Are you using a pump for hydraboost with 2 return ports, or a standard pump with the T fitting?
