Ok, guys. My grease gun will not shoot grease into the new front driveshaft. Looking at the zerks it looks like there is a BB in the zerk which may need to be pushed down to get it to accept grease.

Never seen anything like this. Do I need a special grease gun?

Thanks.

Push the grease gun fitting onto the zerk firmly and hold it on tight, while holding the driveshaft in a vise. pump the gg until you see fresh or new grease escaping from the seals.

Yes, that is exactly what I did. Maybe I need to push the ball bearing back for the first time just loosen it up. Will try again.

But off to see Mission Impossible now. Will worry about it later.

What does the zerk look like?
These?

Or this?

You don't need to do anything special to new zerks for them to take grease.

It looks like the top picture. Looks standard to me but I do not remember a ball bearing in the opening before.

They al have those, it's a check valve.
You just need to make sure the tip of the grease gun snaps on.

you might need a better grease gun, one like this.

They produce 10,000psi pressure, whereas the one you're using isn't more than 5,000.
But if it's really a new propshaft the one you have should be fine. It's possible it's just a defective zerk. Are you able to get any in the other fittings?

No. I started with the zerk on the universal joint and just got a pool of grease outside the zerk. Then I moved to the zerk on the driveshaft and got the same result. Looks like nothing went inside either zerk. New greasegun that originally had just a metal tube; I inserted the rubber line to make it easier to use. Wonder if the rubber line is the problem? The tip snapped on; in fact I had a problem getting it off - pried it off with a screwdriver. However, now that I think about it, I would not say it fit snugly after it popped on. Do not remember how it is supposed to feel - is it supposed to be a pretty tight, airproof fit? Might be the problem - it just does not fit right - good old Pep Boys tool.

Sometimes nothing is easy. Even just greasing a joint. Hate to but might just take it to my indie and ask him to shoot grease into it.

Does grease come out of the tip when nothing is attached? If so, it should work, you just have to push and hold it on the zerk very tightly while pumping. If it still doesn't work, get a new gun.

Well, boo on Pep Boys grease gun. Went to the indie and grease went right in. But still too hot in Atlanta to install on my back. Waiting.

need a better grease gun.. my cheap one from napa has to be aligned just right with just the right pressure otherwise it just squirts out the side

The one I pictured is a Lincoln I got at Northern Tool. Model# 1142, $30.

Thanks for that. Mine cost $10 at Pep Boys. Sometimes you get exactly what you pay for.
