when fitting a new front wheel bearing , is it fitted first to the hub carrier and then finally is the hub then fitted through the new bearing centre.
If so do i heat the hub carrier up and freeze the bearing which then leaves me with just the hub to fit through the bearing.
Since the hub is an interference fit ,do i just freeze it overnight before fitting.
Just a bit confused as to which part to fit the bearing to first ,the carrier or the hub

when I watched my mate pressing them out the centre came out first then the bearing was pressed out of the hub, the new one was pressed into the hub using a spacer that only pushed on the outer edge of the new bearing, finally the hub was inserted, good luck with getting them apart without the use of a press, if you want to use temperature pop the bearing in the freezer overnight and the hub in the oven, probably best to make sure the wife is out

got the hub out using a socket and a club hammer on a granite road kerb. Since i was fitting a new hub, wasn't worried about damaging the old one.
I was left with the outer bearing ring and a rusty immovable circlip. Worked the circlip loose using two flat bladed srewdrivers as it was rrusted in situ and then used the trick from this forum of arc welding a ring on both sides of the stuckfast outer bearing shell and hey presto a few light taps it fell out.
Fitting the bearing to the carrier dosen't seem to be rocket science but i don't want to damage the new hub . Wish i knew someone who worked in a cyrogenics lab and they could deep freeze the hub carrier better than a domestic freezer.

You dont want the hub carrier small and cold you want it big and hot, you want the bearing small and cold.

It's got to go hub out of bearing, then bearing out of carrier; refit bearing to carrier, then hub to bearing. Won't come out otherwise. You want the hub carrier hot and the bearing cold for the first operation, then bearing and carrier hot (but not so hot as to wreck the bearing!) and hub cold for the second. Don't forget to support the full face (or at least the inner race) of the bearing when pressing the hub back in, otherwise there's a chance the bearing will separate....

the new bearing goes into the hub carrier first, i usually get the bearing started and perfectly straight, then use an old inner race in conjunction with a threaded bar, thick round discs the bar can go through, and wind it back into the carrier,
then the same with the drive flange/hub, but mind you place the old inner against the inside new inner, otherwise as the hub goes through the outer inner race it will push the inner inner race out of the bearing,
a never use any heat/cold

NO NO NO!!!!! down boy do not put the carrier in the oven at all with the bearing fitted,
the sugestion made above was to expand the carrier and shrink the bearing, to make fitting the bearing into the carrier easier,
and not for the process of fitting the hub/flange into the bearing

If you know anyone with a CO2 fire extinguisher they don't want anymore, you could stick the drive flange in a bucket give it a good blast.
Although to be honest it'd probably be a lot easier/cheaper to pop down to a friendly garage with a 4 pack and ask if you can borrow their press and collection of assorted bits of useful metal for 20 minutes
It's considerably easier to get the flange in the bearing than it is to get the bearing out of the upright.

You are not a dumpty, just lacking the relevant knowledge. We all suffer from that in certain areas, hence the main reason for the existence of this forum (other then for general chit-chat and cracking jokes!).

If the bearing and hub are an "interference" fit , is it not better to use no lubricant at all during assembly, althought it may make it easier and quicker to assemble.
down boy do not put the carrier in the oven at all with the bearing fitted,
