i added a spacer to my front hubs and had to remove a small bolt that fits into the wheel hub. It stands out like a small stud although it is obviously not one, and when i removed it, it seemed to be doing nothing.

What is this screw/ bolt for?

 

To make sure you don't try to put the rear wheels on the front.

Just take a journey into the top 100 questions.

I have heard it holds the taillights in, i wouldnt risk the ticket, so i bought rims that didn't need me to pull it off.

Typing drunk is a pita

 

You were supposed to let him find out the hard way about the taillight.

 

wtf? wow, im talking bout the metal piece that the wheel sets against has the screw. Think emporer is right.
Thanks
