Monaco Trivial Pursuit-Upper Steering U-Joint

[DonBaja]

I am new to this Class "A" thing and have a "new to me" low mileage cream puff '95 Monaco Dynasty. I am trying my best to be a good steward and the manual says to lube the 3 steering U-Joints. I got to the lower two and can see the top of the upper U-Joint but cannot see a zerk. This upper U-Joint looks pretty pristine (like it has never faced a grease gun). Does anyone know if, should, or how this puppy can be lubed? Thanks.

That one is inside the coach under the plastic steering column cover.

Steve, I have the U-Joint behind the upholstery lubed. The third (uppermost) U-Joint is the one that allows you to tilt the wheel. That's the one I am having trouble with.
