Has anyone seen if the hubs and axles from a G6 would swap into our car? I am sure that they are beefier than the stock cobalt toothpicks.

 

no on hubs no on axles. the bolt pattern for the wheel bearing wont match, need to use grand am wheel bearings that means new wheels. GM sell the G6 knuckle suitable for the cobalt application do a search here for the part numbers. The axles wont fit if you do the grand am wheel bearing swap you need to get new outer joints and shafts to match...forget it buy the performance knuckles...
