Hi guys so i am having problems with the steering on my 8011,so i changed the steering pump and fitted a new one and the steering is still heavy,so then i chaned the steering unit which is under the radiator(mine was leaking)and still the steering is heavy.What else does anyone know might be wrong,i seen people had trouble with the power steering relief valve,what does this do?Alos is it the valve located on top of the power steering oil tank.Any help would be great guys.And thank you
