grease fitting headache!
The grease fitting on my passenger side front wheel, the top one that has a bend in it will not take grease. I've changed it out twice with brand new fittings and it still won't take it. All the others take the grease well so it's not the gun--which is also new. Any ideas?

Are you talking about the upper ball joint?
Try lifting the wheel off the ground. This may relive a little pressure in the b-joint and let the grease in there.
Also, remove the fitting and use something sharp to clean out the grease fitting hole.
If all else fails there is a tool that will get the grease moving, you use a hammer to force the grease into it, you will need a straight fitting too, the 90 will snap off.

You might be hitting the ball but be sure before you get physical with it. There is a nylon bushing on some of them. You should be able to tell when probing the opening. The ball is hardened but can be hurt. Use a sharper tool and wiggle it around the top of the ball/socket.
Did you take the pressure off it? Might help?

I did take the pressure off and nothing. I know the guy down the road from that runs a lube shop and he tried his air pressure grease gun and still would not work. He said to take the fitting off and shoot PB Blaster up in there and let it sit over night. Then work something sharp up in there and see if that works. I don't know about all that, what do y'all think? Your link doesn't work for me. Can I take the wheel off and take the kingpin out and see what is going on that way? Is that really hard to do?

According to the cutout you are probably hitting the Ball.
I would guess that the passages the the grease flows through are just good and plugged,
PB Blaster may help particularly if it's top joint. I don't think that there is a quick fix unless you have a Very High Pressure tool like the one suggested that is used in conjunction with a hammer.
Put some PB Blaster in there and if it disappears,put some more in it and drive it around for awhile.
I used to have a hand gun just for these pesky Zerks. It put out 10K PSI and in most cases worked like a champ.
Good luck,
Rog

Yep, I really thought you had the tire off already, that's going to help a lot.
Maybe remove the brakes too.
PB Blaster or any grease/oil solvent will help. The grease has hardened or is packed with a dirt/grease mixture.
Last resort: You can try to warm up the joint to melt the grease but......a heat gun or propane torch would be safer than Oxy/Acetylene.
Is the joint loose or sound dry when moved? If not, I would just drive it...fix it later.
BTW: My pneumatic grease gun has about the same pushing power as a manual gun...must be a cheap one
