>> Stay informed about: wheel hub
Take it somewhere else. It's more common for right front bearings to fail, because you get more potholes and half ****ed repairs on the right side of the road.
Aftermarket hub/bearing assemblies are equally reliable, and GM (obviously) has a design flaw in their design. Take a drive around your area and look for a repair shop that has a lot of contractor's trucks in the lot. Have them do the job for you, and tell them your story. Ask them to use a premium quality aftermarket part.
Also, do your homework. Check with local parts suppliers to find out what's available, and what the list prices are for whatever they have to offer. Pricing will give you a clue about what the repair shop is selling you, and most honest shops will tell you who they buy from.
