So I decided to use the Napa brand wheel bearings and chassis grease on the bearings cause that's what I had in my grease gun. I put the drivers side axle in first and I noticed that with it all the way in and bolted up that when I turn the axle the pinion yoke doesn't really move, it kinda does but not like It should, when I i stall the passenger side axle then the pinion yoke will turn when I move ether the drivers side or passenger side axle shaft, is this normal? It's a non sure grip 741 case.
