Pretty much without exception, every time I apply grease to to a component with a grease gun, I pump the handle until it squeezes out somewhere. I understand that is not the correct way with GMC Motorhome fitted with front wheel bearing zerks because you will "blow out" the rear seals. So what is the "correct" way to grease them (how many "pumps")? But here is my real question: Couldn't there be another hole drilled somewhere in the assembly with a removable plug that you could remove the plug and pump grease into the zerk until grease comes out the hole (and then replace the plug)? That would give me more assurance that I have applied enough grease, and hopefully prevent blowing out the rear seal. Is that realistic?
