Someone either used crappy parts or they damaged the bearing putting it in. The bearings on these cars are massive FAG and last 150k or more if they are OEM. I had one go at 150k and one at 175k and I was the earliest failure until your post. Replaced the original Volvo bearing at 45,000 miles, so ...

Original poster here -- took my car in to a Volvo specialist and it was the left-front wheel bearing. Makes sense but the only reason I did not expect it was because I replaced both front wheel bearings at about 45,000 miles (car now has about 82,000 miles on it). Noise is now 100% gone.

Is the rumbling sounds speed dependent? Could it be air causing one of the plastic wheel well or under engine covers to vibrate? Could it be one of the belts or pulleys rubbing against something? Thanks so much for the advice, I will do everything you suggested and see. Funny thing is I took it to ...

Bought my 2007 2.5T S60 with 45,000 miles on it almost 5 years ago. Quickly noticed a soft but consistent rumbling sound and sensation under driver footwell. Mechanic dismissed it, saying "That's just Volvo's, they're quirky like that, don't worry about it." Then I drove in my friend's 200...
