Do not hear / feel any bearing problems . For what that is worth .
In my youth , pickup wheel bearings , were the kind that you could take out and hand pack . Would a 2007 Chevy have that type or the sealed bearings ?
They can be loose enough to mess with the sensor air-gap but not make noise.....Yet.
Some bearings make a TON of noise & not have any slack.....Just last week I did a rear wheel bearing on a 2003 Sequoia that was raising [censored] with .003" axial end play & .001 radial end play.
GM has used sealed hub bearing in all light duty trucks since the introduction of the GMT-800 platform, And only 2wd GMT-400 trucks had seviceable tapered bearings.
Retrieve the Current & History DTC's out of the EBCM & proceed from there!
