I am doing an overhaul on my boat trailer hubs. I want to change out the bearing cups and am having trouble removing the old ones. They seem to be in there good and don't want tto budge! I think they've been in there for many years as I purchased this boat and trailer second hand. They appear quite worn, so any help is much appreciated. The inner and outer bearing cups are the same size. My hub took 1.25 inch inner and outer bearings.
