I have been told that you need to jack up and turn wheels with the center grease fittings as you pump in the grease. Is this true? I've been doing it and its a pain to jack up all 4 wheels.
Thanks

curious... are you pumping until you see grease come out of the front bearting or just putting a few pumps in there?

I am not quite sure how much to pump in. The instructions are vague. Too much will get on the brakes and too little won't reach all the bearings. Suggestions on how to tell?

In my experience, farming for about half my life, as I spin the wheel, I listen for a "crackling" sound as I pump in the grease, which is air being forced past the seal. At that point, I'll give 1 or 2 more pumps with my manual gun, and stop. With larger bearings and an air-gun, we'd use the same method, with very few problem. Yes, we occasionally blew seals, but it was very rare.

So, how did you know when you blew the seal? On a fifth wheel trailer if the seal blows you grease the brake shoes & magnet... hard to tell that the brake on one wheel isn't working. ( I should say it's hard for me to tell.)
