Question Wheel bearing replacement issues

Hey there,

So I've replaced all of the wheel bearing front and back with the Pivot Works kit from All Balls.

I've done this on both my 07 250s.

It's safe to say I'm terrible at driving bearings or I'm doing something wrong.

Getting the old out no problem. Driving the bearings I used sockets that only contact the outer race. I was careful not to hit the inner race. Froze the bearings the night before.

Current issues post replacement:

Black Ninja
Rear- wheel bearing tight on internal wheel spacer, does not spin freely
Front - same

Blue Ninja
Rear spins freely but grinding. I hit the inner race on one bearing to loosen up the internal bearing to increase clearance. Probably self-inflicted on this one.
Front spins but has a clunky thud on my balance stand. I can feel the clunk spinning with my hand.

I measured the old and new bearing they match.

Questions:

Is there a order to installing the new bearing?

By seating the bearings into the wheels the spacer is tight. Did Kawasaki not seat them fully?

Any help would be appreciated, I'd like to know I did the bearing job correctly, definitely don't want them failing on the road.

I've bought another round of bearing different mfg this time and a bearing driver kit.

Thanks,
Jay
