Upper ball joint won't take any grease.

[chrger1967]

I put in a new set of upper control arms and tried to grease them up the ball bearings today. Well, for some reason they will not take any grease. I first I thought it was the zerk fitting, so I changed it. Then I took off the zerk fitting and put it in the grease gun and grease was flowing now problem. Could these be bullshit bearings and I will just need to change them too? I have to say, I've never run into a ball bearing that won't take any grease. When I try and fill them, all I get is pressure on the handle of the gun like the flow is being stopped, very weird.

Jack the front end up, have someone turn the wheel back and forth while trying to grease.

I have the car up on jackstands with the front end, you think I should put a jack under spindle to lift up and take some pressure of the joint as well?

Can you unscrew the zerks themselves to make sure they arent frozen and not allowing any past??

Oh, yeah. I took one out and hooked it up to my grease gun to see if grease would flow thru it, and it did. The car is on jackstands, tomorrow I'm going to try and also raise the spindle with my floor jack, maybe that would help?

Are the zerk threads too long and bottoming out against the inside of the ball joint?

Good question, but they are all the same length as the one that came with the ball joint. I did see on a video, the guy was explaining that the joint itself is under pressure, it might not take grease. I'm going to try jacking up under the spindle, ease up on the joint and maybe move the wheel back and forth a little.
