When greasing the king pins on my roadster, I discovered one that was plugged. Taking it out was easy, but putting it back into a tight spot wasn’t. It kept slipping out of my grasp.
Here’s how you can solve this issue in two easy steps:
1) Install the fitting into a piece of tubing and use it to twist the grease fitting into the spindle.
2) Remove the tube, slip a socket over it and tighten it up.
This method can be applied to U joints or any nut or bolt that gives you a problem.
