So in the process of installing my new ARP wheel studs I had to take apart the whole wheel spindle/ hub assemply, and decided to replace all of the bearings and seals while I was at it.

The fronts came out great, without any play, however the rears (one to a more severe extent than the other) seem to be crap. When I move the assembly around I get tons of play in the hub end of things while the spindle doesnt move at all, leading me to believe that the bearings are either DOA or that I did something really wrong in the instalation?

I used brand new, albeit cheaper than stock chinese bearings from discount auto parts, and I used a press for all of the work. I merelly replaced everythins as it was, simply using new parts.

Any ideas on what might have gone wrong?
