Wrong place to ask

You look on parts web sites
You look at auto part sites
You may at a salvage yard get cross reference data
Auto Parts Store if want to may look up several vehicles
to answer that

What you NEVER do is install any used part in any vehicle

What you do is go to Rock Auto.Com & buy a new or reman
& install it

No reason to even get into this

Just buy a new part,you do not want used in a
drive axle & have an unsafe vehicle

You have to know the year and specific model of your SVX. Any Subaru parts department will look up the part number and also tell you if it is the same part as other models. They may work with you over the phone.

loose bolts somewhere in the front end? you have had lots of work done there. wheel weights can fall off or a rim can be difficult to balance?

junkyards, ebay, craigslist

Check wheel bearing.
Check backing brake plate , sometimes it's bended and touching brake rotor.
If wheel bearing is bad , you may have same effect with backing plate , brake rotor touch backing plate.

you need to remove door panel to unplug miroor connection

Have you already removed the axle from the car?
