Wheel bearing seems loose?
 

I was wondering of the wheel bearings inside the wheel bearing
hub assemblies are replaceable? My driver's side has much more play than the tight passenger side. If not what is the wheel bearing assembly part number?

Thanks,

Gert

hub and bearing should be- 7470587- $292.36 list
knuckle right side-18060621 - $239.72 list
knuckle left side- 18060620 - $239.72 list

i would double check for number superceeding these but they should be good..GM part numbers.
