Replacing greasezer/keeping garage floor clean

[vilasman]

On my front propeller shaft , I believe there is a grease zerk in the knuckle joint or yolk joint....in the joint. The head of the grease zerk seems to be worn off -there is nothing there for the grease gun to grab hold of. Do I need to replace this zerk? Is it really hard to get to?

I'm moving...to a house with a garage. Assuming the cruiser will fit in the garage what do I put on the floor to avoid grease spots?

Don't know how it could be worn off unless it was damaged during yoke replacement or something else.

Yes, replace it. Hex at the base.

Paint your garage floor to help keep it clean. Don't forget to add the anti-skid grit. Does get slippery when wet.
