How old is the camper? Ours is 4 yrs old. I had a hub that was getting a lot hotter than the other 3 but I wasn't getting the jerking you do. I repacked all the bearings an that same hub still got warmer than the others. The brake pads an the electric pad didn't look too worn but I replaced the whole brake assembly on both sides of the axle anyway. Now all 4 hubs are within 3-4 degrees of each other. It cured my problem.
Strange thing is now all 4 hubs get hotter than they used to after all that brake replacement. Went from an average 98 to 108-110 degrees. Not sure why the increase but at least they all increased together
