What could be causing a Squealing/Rubbing Noise When Turning Steering Wheel?

Hello, that sounds like a lot of proactive guesswork trying to solve a problem they don't know how to resolve. Although those items may have been performance improvements that will help your Mazda, I'd suggest that it didn't resolve the root concern, which is frustrating. I'd recommend a shop near you that specializes in your vehicle and client service is enlisted to check out your noise. Since we cannot hear noises or see your vehicle in this forum, anything I'd suggest would be guessing and probably not a great guess! After all, we don't know if the rubbing noise you are hearing is originating inside the vehicle or outside the vehicle. https://repairpal.com/auto-repair-near-me Click the link or call us at 877-913-1554.
