you can remove air by turning wheels slowly all the way to right, then left. go slow or you will foam up the fluid and still have air in. if fluid is foamed up let sit and cool down then refill and turn wheels again.

Suggested Repair

Bleed air by slowly turning the wheels fully right, then fully left. Turn slowly so the fluid does not foam. If it foams, let it sit and cool, refill, and repeat the slow lock-to-lock turns.
