I need to replace the front hub/knuckle on my 04 Impreza(it has abs). Does anyone know what years and models I can get it from?  Also a link to a good write up (for a novice) on how to do this without  power tools would be greatly appreciated. Thanks in advance for your time.

I'm guessing someone smarter will chime in, but you can do some comparison on opposedforces.com and match part numbers.  You can also do a similar maneuver by looking for the part on an auto parts site (e.g., Advanced Auto).

Assuming you are going to get a used knuckle from a salvage yard, have it include the ABS sensor if you can.  Removing your old ABS sensor to reuse almost never works as they get frozen into the knuckle and you end up breaking it while trying to remove.  I've had success with $15 ABS sensors from eBay.

Go to car-part.com to check interchangeability 

car-part.com is great starting point for interchangeability. put in the part you need and then take note of what other vehicles it's cross referencing - any legacy/outbacks - what years?  what year imprezas?

Thanks, I  checked out car-part.com but got some non consistent answers when cross referencing. I was hoping someone on this site could let me know what their actual experience is.  I also called up a couple of dealers and got different answers.  Specifically I would like to swap an 04 Impreza TS knuckle for an 01 legacy,  and then a 92 legacy for an 01 legacy.    The 92 legacy does not have abs so no worries there.

Go to https://parts.subaru.com/ and select the appropriate model/engine/transmission for your vehicle (or use the VIN lookup)

Click on the All Categories then Suspension and Brakes

Scroll down to Front Axle Housing and click that 

 

 

That takes you to the above image

If you scroll down and click on the part number it brings up this page
