I know some people call them knuckles but Roger Penske and the Indy Car guys have always called them by what function they perform. Roger is not returning my calls so I have to ask this of the forum.

Do I need to support the inner race? Or can I use the old bearing to support the new bearing? When I do this it is supporting the outer race and I’m not comfortable with that. I don’t want to do harm to the new bearings.

I tried freezing the hub (inside part) and warming the bearing which has worked for me with bearings but not this time. Now I’m stuck

What’s the best way?

Jack:
I think you got the warm/cold in reverse.

cool down the bearing or warm up the knuckle.

I used my 12 ton press and heated up the knuckle a bit; eventually it expanded enough to allow the bearing to seat.

I would guess freezing the bearing would do the same thing. I would recommend you don't do both at the same time.

Support the inner race from the other side and press the hub into the bearing. Otherwise you will damage the bearing assembly as they don't go easily. I used a piece of steel round stock just barely larger than the inner race.
Have you already installed new bearings?

I have the new bearings in the hub carrier. I froze the bearing and warmed the carrier, the bearings dropped in. Now I need to install the hub into the bearing. I cooled the hub making it smaller and warmed the bearing (making Bigger) which is in the knuckle (I hate using that word in this application). It started in but stopped. I know when I pressed the old hub out it took some pressure in an arbor press. I guess I’ll have to go to work tomorrow and use the arbor press.

Thanks BS

Unless you have a pretty stout arbor press I would be surprised if it has enough power to press in the hub. A hydraulic would be much better. My buddie's 12 ton hydraulic was just barely enough to press in the hubs. A 20 ton would work better.

I mean a hydraulic press. I'm sorry. I think it took close to 20 tons to push the bearing out but I figured that was because they were in their since 1994. I have access to a 20 ton press, heck I have access to a 430 ton injection molding press. I sell injection molding and mold making services.


Thanks again BS you are giving me good information.
