Top kingpin zerk won't take grease

Did some searching for my problem here first but didn't find anything.
The driver's side kingpin top zerk won't take grease. I pulled grease zerk and checked it - its fine. Looks like this might be a job for the local shop...but wanted to see if anyone has experienced this. There is a 1" "nut" or "bolt head" on top of kingpin that zerk screws into. I'm assuming this holds the whole thing together and would be a bear to remove. Would have to remove the wheel and I don't even have the tools to do that. Thoughts?

Oh, its a Dana Spicer axle that also had "TG104" on a metal tag on this zerk.
Thank you!

It has been a long time since I experienced this problem. The shops just raise the power on the grease gun and try again. I was able to get the grease in with a hand gun by reducing the pressure on the king pin. I used a jack to raise the axel and turned the wheel with the steering wheel till I found a position that allowed grease to enter.

Good luck.

Hand pump grease guns come in different pressure specs.

Here is a 10,000 psi one that may push thru the blockage.

If it works, keep flushing out the old grease, while turning the steering lock to lock.

If you can jack up the axle and take the weight off the wheel. That may let you grease it. Also a high pressure grease gun helps greatly.

Definitely raise the coach to get the weight off the king pin. The load on the spindle against the kingpin may be restricting the grease entry. This may be a blessing in disguise as the kingpins will generally take grease much better with the weight off the wheel. You might discover the steering is much easier after greasing with the weight off the wheel.

Since the king pin is round and vertical, with the fitting in the top cap, lifting the axle will only unload the pin off one side of the bushing. Sitting on the ground, the other 3 sides are already unloaded. Think door hinge.

Both brass and plastic bushings have spiraling groves in them so the grease travels around the pin, in any position.

Lifting the wheel AND turning the steering, while pumping the gun may help break up the hardened grease.

High pressure, extreme heat or disassembly is the fix.

Also, replace that grease fitting. They do get clogged/frozen.

Thanks EVERYONE for the advice/help. I'll see if I can get my 20 ton bottle jack under the axle and safely support this thing while I'm under it. Think I'll raise it with my leveling jack to help take some weight off.

Problem Solved!

Followed y'all's advice: jacked up front axle, turned steering wheel back and forth stopping in a different position from original problem, zerk took grease with no problem. Pumped a little, turned steering a bit more and greased some more til I had new grease coming out.

Again, thank you to all who offered help!
