Ball joint remedy

One of those unusual sequences of events here..

I'm driving south for a couple of days surfing and lamenting the knocking noise coming from front right suspension. I've deduced that the only culprit left is the upper ball joint. And the only way to fix it is to either replace it... or get lubrication into the joint.
I know, I need a syringe full of oil to inject through the rubber boot !

Now just as I had that thought I had to pull over for a leak.
Whilst staring at the ground what do I see ??? A syringe.
I don't want to know how it got there, but I do know it solved the problem ( for now )

ps good surf today.
