I have a 4" dropped axle set-up from Speedway. I ordered the spindles and king-pins from them also. The question I have is on the assembly, since they came with no instructions. In the king pin set, there are 2 felt washers and metal "cap like washers". I understand that the bearing goes on the bottom of the axle between the spindle and axle. There are a couple of thin shims that came with it, and I am guessing that they are for on the top of the axle/spindle area for fit. Where does the felt piece go? The spindles have 2 tapped holes in the top and bottom where the king pin goes thru. One appears to be for a grease fitting and the other for a set screw. Does that set screw just plug that hole, and not get tightened down on the king pin? There is a set screw on the axle that, I think, holds the king pin in place.
Am I doing this right?
