Borgeson steering

MUCH moore work then expected. Had to fix one tub at the header. Fix the hoses. Bend the tube at the pump for returnoil and on..........
But now it is running. Have some noise and groan when trying to steer. Both when sitting in idle and at crusing. More to the left then right but to both ways. Running semi syntetic oil. Anyone got the same problem? Will mineral help?
Done the bleeding by the borgeson webpage. No airbubbles in the oil. Printed all the papers at borgeson. Cant find any contact adress for mail.
I am out of ideas.
