Review on 🔧 Enhanced ACDelco Gold 513121A Front Wheel Hub and Bearing Assembly by Bruno Gilbert

These are original Delco bearings! I have one that was the HD variant. Having several GM cars in the family and owning a few, I have changed many wheel bearings and this is by far the best I have come across. No luck with frugal bearings, I wanted quality. They come with clips and various holders so they can be used in place of 513179/513199/513187/513121. The different numbers are just the difference in the clip or clip holder, the bearing is the same, just for reference. Also follow the torque instructions for long life, the hub nut does not need to be tightened with incredible force! I think a lot of the bad reviews about bearings come from people over tightening the hub bolt (CV). The hub screw does not hold the bearing! The rear bolts will fit, they just keep the CV from moving and bumping, so stick to the 100 ft-lbs listed for your vehicle. I made this mistake out of frustration with the first camp I ever made.
