Hey folks after running close to 3000 miles over 18 months I gave each wheel 1 pump and blew 3 out of 4 rear seals. That is the way I had done for 10 years on previous trailer, and never had a problem.
Something has changed and we are not aware of it.
What brand is your axle/hub/bearing-grease mechanism? Mine is the AL-KO Ultra-Lube. My directions specifically call for pumping grease until it comes out the front. In an exploded view of the wheel-hub assembly it clearly shows the center of the spindle with a grease channel. The grease hits the rear bearing and then fills the cavity between the rear and front bearing then fills the front bearing and out the front.
