Some trailers with disc brakes require you to pull the calipers off to remove the inner bearings.
Last Tuesday while up at my neighbors camp I started to install the new tires his Dad had bought for their aluminum boat. I took the hub and spun it and one was grinding loud and when I pulled the hub the roller bearings fell apart. It had been bad for some time with gritty grease/water mix. The boat ramp is 3 blocks away from the camp.
