I have bolts in mine. Swore I would never put those God-forsaken spindle pins back in. If they seize up, and you have to have a special tool to take them out, WHY would you put them BACK in? Its a terrible design IMO, and I'll never use them on another car I have. Almost 10K miles, and they've been apart a half dozen times, and zero issues. Cost me all of $10 or something at the local hardware store.
