Just installed a TF levying kit. The new swaybar linkage had a hole for a tiny bolt to go into it.... what purpose does that bolt serve?

Let's say, hypothetically, someone lost the two little bolts... what would that do to the linkage? Here is a pic.

Do you mean the grease fitting holes?

 

They are grease fitting any hardware store should have them.

 

I bet that's what it is. It was on the side with the pivoting section. I'll go to lowest and grab some more so they don't dry out.

 

They have been off for a day now, should I add grease/lube or should they be ok?

 

Just use something to clean any dirt out of the holes and then grease them up. You'll be fine.
