I am in the process of putting new hubs on my Road Master trailer and I came across an odd thing and was wondering if anybody else has experienced this. When I put my new hubs on it requires me to put two spindle washers per side. To make matters worse when I took the old hubs off the driver side had two washers but the passenger side only had one washer. If I don't put two washers the hub doesn't get tightened enough and is loose? Is this anything to worry about?
