Bearings fit pretty tight onto spindles. There basically should be no play at all between the inner portion of the bearing and the spindle. They don't fit so tight that they would have to be pressed on, but they sometimes can be tight enough that they require a bit of effort to get them totally slid on.

Answer 10

The rating of the axles only determines the amount of weight the axles can bear; in regards to hauling more weight you are limited by the lowest-rated component. For example, if your trailer had a GVWR of 6,000 lbs and you put a pair of the 3,500…
