I've had some mild-moderate vibration in the wheels/suspension of my '17 Touring for a while now. I had been attributing most of it to the stock Continental tires that were getting worn down and had incessant scrubbing noise from the tire bead against the wheel rim, or from a slightly out of round wheel. Discount Tire told me one wheel was bent when balancing, but I never really noticed any vibrations attributable to one specific wheel. I recently replaced all four tires and had the dealer road force balance them (so they say) as well as replaced front rotors and pads. I continue to get an aggravating vibration while driving. I've tried moving wheels to opposite corners, but no change in the vibrations. I've jacked up the car and tried to move the wheel by grabbing at the 9 & 3 positions, as well as 6 & 12, but can detect no play in either of the bearings. I do notice the same clicking type noise from both rear wheels when spinning them by hand, but this may be normal. On the left (driver) side, I can feel a slight vibration in the shock tube that's not present on the right side. See videos below. I also notice a very slight "womp, womp" noise on certain roads. The tire on the right rear looks to maybe be out of round while moving (see video). There is also a mild howl/growl noise that sounds like tire noise, but being new tires, should be quieter I think. The noise seems more noticeable when turning right. At slow speeds, say 30-45MPH I can feel a slight wobble up and down, but again only on certain road surfaces. I'd think if it were a bad wheel bearing causing noise and vibrations that the shake test would reveal some play in the hub. There doesn't appear to be any tears in the CV boots and no grease on the undercarriage anywhere.
I'm not really sure where to go next in troubleshooting this issue. If I could be certain it was a front wheel bearing and it was obvious, I'd just take it to the dealer and let them handle it since the front wheel bearings should be covered under the 5/60 powertrain warranty. I'm worried I might have a bent half-shaft or worse, something wrong in the transmission. Anyone have any thoughts on what my next steps should be. I do have a set of 18" sport wheels/tires that I've had on the car for a while before replacing the tires. I could swap them over and do another road test I guess. I'm getting frustrated and just want a smooth ride again
