The term is "churning" and it will build up heat which leads to seperation of the oil from the carrier base. The void in the hub is for a small reserve but more than a ping pong sized extra glob is more than you need.
I will admit to using the grease zerk before the big trip this week. Having ran out of time I took a short cut and shot in some grease and tried to call it good. On the way out of town we dropped off a bill and driving close to the building I heard a low growling noise. Fearing a bearing problem on a 800 mile trip I took Chubby back by the house and removed tires and hubs.
Since my 4x8 and my 40x48 HF trailers share the same hubs I stole both off of Eggbert my motorcycle tear and put them on the 5x10.
I bought my HF 4x8 used and I assumed all was well, however the rear bearings had been bone dry prior to my 3 pumps of grease and the bearings were much the worse for wear.
Thank God I heard the noise I would much rather work at home as opposed to on the interstate with semi's nipping at my butt.
So If you have purchased a used trailer as I did , don't asssume that the previous owner did anything right, take it apart and clean and visually inspect the bearings then repack them.
