Wheel bearing replacement question
 

Is this an accurate video of how I should go about replacing a wheel bearing & hub? [ame]https://m.youtube.com/watch?v=cBRsE72LqzI[/ame]
Also what are the part numbers/a reliable website to buy them from?

Yep. Pretty simple fix.
As for part numbers and where to buy you have a few choices:
1. Call your local dealership parts department.
2. Goggle Subaru oem parts catalog.
3. Your local auto parts store. Call or visit their website.
4. Rock Auto.com.

I like to use a new axle nut. I haven't had good luck reusing them.

As per the repair manual, axle nuts should be replaced once removed.
Just a little FYI if you didn't know that by now. If already known, please disregard this message

I did, though I did try getting away with reusing once out of cheapness. I noticed in the video he reused the old nut.
