Default Re: hard steering f-100

Try lifting the pickup at the axle and take vehicle weight off of the king pins leaving the front tires still in contact with the floor. Then pump the grease into the zert. Yes you should see grease come out of the top and the bottom of each knuckle. Highly recommend using jack stands under the frame rails while doing this task, don't trust a jack by its self. I also grease my leaf shackles with the vehicle weight off of them and pump till grease comes out both ends. Keep us posted on the out come.
