EZ lube spindle and bearing repack question

UPDATE...Over the weekend, I thoroughly cleaned and repacked my bearings by hand. Bear in mind, I bought my camper brand new a little more than a year ago. 3 of the hub's bearings had a decent amount of grease in them, but the fourth barely had any. The bearings themselves looked perfect. Three of the four seals had leaked a little grease into the brakes area, but thankfully had not gotten on the drum or brake pads. I was able to clean up the grease. I cleaned and repacked all bearings by hand, replaced with new seals, and never touched the grease gun. I readjusted the brakes. I also checked the bolts that hold the brake assemblies backing plate to the axle. On 2 of these backing plates, the nuts were just barely finger tight. I snugged these up good. For a few hours work, I feel better about the situation.
