I rounded a driveshaft bolt with a crastman wrench when I first started in the auto buisness 25+yr ago and my boss came over and removed it with a snapon wrench.I will stick with snap on for my paycheck and crafstman for my weekend fun.
Half shafts is not a common problem on the newer chevy's.Rust on the mounting suface of the sensor is common.Be carefull of the 122 dollar bearing you might be doing it again in a year.I did on my truck when I knew better!!!( 25yrs turning wrenches) Hope this helps.
