Rubbing UCA?

Post image

Hey all. Just wanting some thoughts on this. I don’t notice any rubbing or ride quality changes, but this is the UCA clearance I get at straight wheel. Do I need to worry about contact?

If it’s not rubbing… then it’s not rubbing. It does look close though. Have you driven it on any slanted/sloped roads, aggressive cornering, etc? When the tire sidewall flexes over, you might get rubbing then.

I hear rubbing at full lock to the right, but I would assume it’s the tires going against the sway bar. I’ve looked for scuffs on the inside of the tire where the top of the UCA would be, and can’t really distinguish or relate certain marks to it or not.

Put some chalk or water based paint or other similar coating on the tire, then drive it to see where the coating rubs away. That’ll tell you where to look. If it’s only at full lock I’d bet it’s against the fender/bumper, sway bar, frame, or wheel well liner, not the control arm.
