I just lubed my axles w/ the zerks while coach was raised up and spinning the wheel at same time. Found 1 brakes was actually dragging a bit compared to the other 3 as it didn't spin as freely. Has the never adjust brakes to boot. So when done greasing, I used 1 screwdriver to raise up the "locking" tab by adjuster wheel and another screwdriver to spin th adjuster wheel. Got it so it was same as the other wheels.
FWIW, I have a locking device on end of grease gun (pistol grip type) so when it's locked onto the zerk, I can easily spin the wheel w/ 1 hand and pump the grease w/ the other.
