I have a 2009 CX9 Grand Touring with 105k miles. I just had both front wheel bearings changed about 6 weeks ago, everything was smooth sailing until last week.
Now, I have an intermittent grinding/vibration. Start it up in the morning, drive it for 10-15 minutes and it starts to grind... Then it vibrates and actually shakes the steering wheel, almost like it would with a bad tie-rod end or a seriously out of balance tire. I can see it in the steering wheel and feel it in the gas and brake pedals. Hit the brakes and it shakes like mad. Then, five minutes later, it all goes away, everything is smooth. Sometimes it comes back 20 minutes later, or 5 minutes later, or not at all until it's been sitting for a while.
I have NO clue what this could be. From reading other threads on the forum, I'm thinking either the pilot bearing on the rear driveshaft, or the new bearings weren't installed right/torqued down right.
Any ideas?
