Re: 35 spindles and axle worn. Looking for a needle thrust bearing
jimvette has it right, thats where the felt and its dust cap go. the load from the car is on the bearing on top. that space is controlled by the lock pin in the king pin, and shims if necessary, and the spindle can not slide down far enough to ever fill the gap, or touch the axle boss and spindle together. a big gap at the top would be a problem, the bottom supports nothing, just needs the felt
