I have always found these to be a PITA to install. I have tried installing the rear bearings after freezing them and cant see any difference.
If expansion and contraction are proportional to the temperature then dry ice at -109 F should make a big difference. Used in combination of putting the 911 front hub in the oven at 250-300 degrees I am hoping the races will drop right in. Anyone tried it or have an easy method without the proper too size puller tools? |

I haven't changed mine out but every other German vehicle I've worked on has little gaps in the backside of the hubs behind the races - I take my punch and walk them out. My set of race install tools weren't that expensive either but then I was making my living with them so the expense was negligible. Before I bought them though, I'd take the old races and stack them on the new ones and gently tap them into place.
I'd think your idea of dry ice or just putting them in the freezer for hours will work fine. |
