OK. Now onto the task at hand.

I do these at the track.. but I use the proper tool

and I use MAPP gas to heat the carrier prior to the install of the bearing and I freeze the bearing prior to install.

The rear is hard to do and requires quite a bit of physical labor that cannot be avoided.

The first thing I'd like to ask:

How are you going to break the axle nut loose? or torque it properly when you are done? (340lb ft!!!) Most "home users" do not have a $500 LONG torque wrench capable of torquing the nut properly. I'm willing to bet ANY Porsche shop you take the car too will have ONE of these large torque wrenches that is shared amongst their techs.

I'm not trying to discourage anyone from trying to do this at home.. but you need to be real about this. Some of the "markup" helps techs pay for the special tools that you are asking about here.. and pay for tools you are not asking about!!
