Diagnosing CV joint versus Wheel Bearing

[RBRx]

My fathers car (05 aveo) has had a loud rumble for awhile so after ruling out tires we guessed bearings as a cause. Last time the car was driven I was told it was twerking the steering wheel quite a bit and deemed the car unsafe to drive so he's using mine for the time being while I repair his.

So now on to today after diagnosing* which side it was on (front passenger) ruling out brakes im not sure of the cause since there was no slop in the hub and the CV shaft seemed fine. At this point in time I chose to replace the bearing and I already have taken the hub off the bearing via a slide hammer which by the way I don't recommend unless you feel like slamming it constantly for 2+ hours.

* Side was diagnosed by removing the brake calipers and putting the tires back on then jacking up the car one side at a time then while in drive see which side made more noise.

So here are my questions

1: Do aveos commonly show bearing problems while under load but have no slop while up in the air?

2: Is there any other clues that would show a CV shaft issue besides looking at the boot and flopping it around like a kid?

3: Could it be farther up near the transmission that could be felt/affect in the steering?

4: Im thinking of buying a press to have and use what tonnage would you recommend for pressing bearing in/out like the ones on the aveo?

5: Anyone know a part number/link for the cir clip that retains the bearing since I demolished the one in the knuckle trying to remove it after bearing guts had it wedged in pretty good?
