Grease Nipple Problem on Ford 3910 Front Wheel Hub

[frankmako]

One of my front wheel hub assembly grease zerk will not hold the grease in. The grease will come back out the zerk hole. I can see the sealing ball is missing. So I got to change out the zerk,,,but it is a push in type (press in). Not the type that you can screw out. Never had to replace a press in nipple. I do not have any in the toolbox,,, got all other types. It is a 5/16 nipple and it is round at the base. What is the best way to remove the zerk??? Channel locks and pull real hard??? Drill it out?? Take off hub, work real hard all day??? Cannot grind off or cut level, the hub has protection wings on each side of the zerk. Or just get a grease nipple rubber cap and do not worry about it. I know when I get it out and if I cannot find the correct 5/16 push in replacement, I will tap the hole and set it up for a screw in zerk.

Probably the easiest way to remove it is clamp on a pair of vice grips and then using a pry bar use the vice grips as the point to pry from. It should pop out.
