Flat tire sound, but no flat tire?

[biggd1980]

I just recently changed the front wheel bearings on my 04 Grand Prix GT2. Since then I have been getting a flat tire sound from the front driver side when driving at lower speeds. It is the most noticeable when driving on asphalt (black top style roads). The alignment did get knocked off very slightly after the beating it took to get the passenger side bearing off, and will be taking that in for adjustment. Could the alignment be the issue? If not, any other ideas? The noise wasn't there before changing the bearings.

Did you torque the cv nut down?

Look at the axle nut

Make sure the nut on the end of the CV shaft is tightened down
