2009 GMC Sierra Front end thumping noise at speed.

[Fred Neal]

My Son had a bad front drivers side wheel bearing, lots of play and slop...it was toast. Now when getting to speeds over 40km/h there is a very noticeable thumping noise coming from the front end, feels like its coming from under drivers pedal area. If you didn't hear the loud thumping noise you would almost not notice anything else amiss, the vibration is not that bad compared to the noise. My son removed the front driveshaft today and noise was still there. 4x4 works good still (auto,4H and 4L) noise is still present with 4x4 on or off. I'm leaning on the new wheel bearing is bad, but it feels tight and no play noticeable. Just wondering if anyone has any ideas or has experienced this issue before.

 

Thanks.
