Thinking about it. There's definitely something rubbing/grinding that shouldn't be. Some kind of friction. Especially because I feel the vibration not only in the wheel but in my left foot when it's sitting on the dead pedal. Whatever is grinding is causing enough vibration to allow me to feel that.
And the fact that its only when I turn in one direction that I feel it has to be a big hint as to what it might be. I just don't know enough to diagnose. Ill report on noise tomorrow.
You are welcome! I agree that rubbing and grinding, especially only in one direction may not be a sign of something normal. We will be looking for your update tomorrow and on Monday. Thank you very much for your time.
I'm canceling my appointment with Cadillac. I don't know what I was thinking here. I've had nothing but bad experiences with this dealer.
Right around the corner is this place that seems like a pretty tight operation. As soon as the lowering springs come in I'm going to have them change all 4 tires (the alignment severely screwed up my current rubber.) Already ordered the continental extreme contact dws front and back, nitrogen fill, road force balance, check all suspension components, diagnose and fix the steering issue, install the springs, alignment.
I kind of already went into this subject with the service rep but I understand the alignment specs they're going to go with are not exactly optimal for tire wear and that they're really not supposed to deviate from the prescribed settings. But they're willing to go with my desired specs. I want them perfectly straight for minimal wear. Any advice on this?
I don't know how aggressive our alignments are, but they do tend to cause uneven wear. On my previous M5 and 540i's the factory alignments do actually necessitate some negative camber which does help corner but tends to wear the outside pretty quickly. I actually had an aftermarket camber kit on my M5 that helped alot with the uneven wear. I doubt anyone makes such a kit for our cars, but I'm sure they can be aligned close to straight and with the springs I'm thinking you should be fine. Just my $.02.
