I've got three or four old American made grease guns. It generally is the zirc itself if it won't take grease.
If it was run dry and galls it's a bitch to get grease in.
Yep!! Not greasing often enough cost me a bunch of time taking the undercarriage off my CTL last winter. Couldn't get it freed up to save my life. The way it is designed, the grease has to travel through the axle shaft about 9" - 10" before it "exits" and the crust at the end just wouldn't let it happen. Those fittings have to be greased every 8 - 10 hrs religiously...every other day wasn't enough. I won't make that mistake again!!!!
