2000 suburban. 2wd.

Answer 1

Mine went bad from a curb check.

Answer 2

Wheel bearings go bad because the grease dries up in them. The ones these days are pre-packed. Not saying much, they aren't packed well in my opinion. The seals sometimes go bad and they sling the grease out. It's just the cheap crap that the manufacturers put in these days. Plus, with the all-sealed hubs, the oil doesn't slosh around like on a RWD vehicle's back axle. They cost around 200 bucks to replace...parts and labor. Good luck.
