I have a 2009 Carrera 4S. Car was inspected at Porsche dealership and had major service done 8 weeks ago. All recommended maintenance was completed with the exception of new shocks/struts as I’m getting that done at an Indy. I noticed this weekend that when I brake at low speeds it’ll make an intense grinding noise from the front. Porsche didn’t recommend any brake replacement nor do my sensors trigger any warning. It will only make this grinding noise when completely stopping and it’s sporadic as well. It’ll do it sometimes. Could it be a faulty wheel bearing? Surely Porsche would’ve checked that. Car has 100k miles. Any help would be appreciated. TIA
Not on my 3 series. Had a bad front left wheel bearing that only grinds when braking, and only audible on lower speeds. My guess is that it has something to do with how the load is shifted when braking.
