I would like to replace both front wheel bearings, since the right side has a noticable rough spot.

I have the EBS bearing tool, so:

• Can this only be done with the hubs attached to the car, or can I do the work on my bench (after removing the entire hub carrier/steering knuckle)?
  
• Do I need a special tool to first pull the hub from the bearing (horseshoe)?
  
• Should the final torquing be done with the car on the ground?
  
• Should I replace both hub nuts (L & R)?

Don't pull the hub, that is unnecessary work. The horseshoe makes it easier to get the hub out of the bearing, but isn't 100% necessary. There are other methods that work as well. After that, you don't use the horseshoe. Do the final torque (and loosening for that matter) on the ground for sure. The nut, while it technically should be replaced, honestly can be reused, it is just another part Porsche wants to sell you.

Very true, but knowing Andreas, he'll sleep much better knowing the insides of the ball joint dust boot is scrubbed clean and regreased with imported German grease.

It's funny because it's probably true.

PorscheDoc

Probably? No, it's just 100% true!

The new bearings should fall right in using this method, correct?

It will make them go in easier, but I've never seen one just fall in. Bearings in the freezer helps as well. If you are using the B-90 tool, then it doesn't matter, it will pull the bearing in nice and easy anyway.

Heat the carriers, freeze the bearings. mine have dropped in as easy as the video Chris has posted... then wait thill the bearing and warms up before putting in the frozen hub.

Sorry Andreas, post was meant to be a bit tongue-in-cheek. The pics are from a great post on Jackal's website. see: "RS Bumpsteer kit"

Holy crap, that is awesome, lol.

chris walrod

Yeah, I typically heat aluminum to 250F and magnesium casting to 220F for bearing fitting. Freezing the bearing helps too!
