Dumb Question Thread - No Flaming Allowed

Was chatting with a guy about wheel fitment, he said his wheels touched the suspension only under load while curbing. That struck me as odd and he said “front wheel hubs do have flexibility in them, right now the clearance is so close that when the wheel hub flexes a millimeter or two it touches” and I was just curious if that sounds right to you guys or not. My assumption has always been that all of that stuff moves in relation to itself and it shouldn’t have flex or dynamic changes relating to how close the wheel is to the suspension.

Hmmm. How would a wheel hub "flex"? The assembly moves in XYZ based on what is allowing it to move (ball joints, linkages, etc.). What is "flexing" I'd like to better understand. Unless something is loose, or damaged, or out of tolerance, I can't imagine what that means. In other words, I agree with your conclusion.

This is the little rubber cap for the trunk hinges. Maybe it would work? I don't know the size difference.

Does anyone have a PN for the ITB adjustment screw covers? Realoem doesn't show them. Aftermarket bodge solutions also acceptable.

Thanks, yea they would just not quite fit, then you pound on the panel a bit and they break.

If you haven’t already, give these a try. The plastic seems to be a little bit thicker/stronger than the older style. They also include a foam ring which helps with rattling and improved sealing. I covered this a bit in my build thread if you’re interested.
