took off my rear wheel bearing but my new one won’t fit all the way to the back?

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! First off, kudos to you for getting to know your Aveo! Secondly, let's see if we can't get that bearing on. It's likely that part of the old wheel bearing is still stuck on the axle, preventing the new one from fitting. Inspect the axle shaft and the hub you removed for remnants to see if any races came off. Looking at the old hub might help identify what's remaining on the spindle. Ensure the shaft is clean before trying to install the new bearing. If unsure, seek a mechanic's help to avoid damaging the axle and ensure proper installation of the new wheel bearing on your Chevrolet Aveo. If you have any other questions, please call us at 877-913-1554! We'll gladly find you a certified RepairPal shop in your area!
