If you have a 2000 or later Subaru you can find "loaded" knuckle assemblies for your car.  That means the knuckle, new bearings new hubs, new seals all ready to install.   HOWEVER, I can not find anybody who sells them for a 99 Subaru Legacy.  I have a wagon, although that shouldn't make any difference.  I dread dealing with the bearings and with the rusty knuckle.

Maybe there's somebody doing it as a side business?

Or just run the later model knuckle/hub assembly. They’re Lego and interchange.

Most shops are willing to press a bearing into a knuckle for a nominal fee. This would be far cheaper than replacing all those parts. Same amount of labor. Only downside is having the car apart for a trip to a shop.

Heck, probably would still be economical to buy a junkyard knuckle and have a shop press in bearings.

 

 

We had a customer bring their car into the dealership where I work for a rear bearing. Turned out it had a complete aftermarket knuckle installed not long ago (not purchased from a retailer willing to help with the replacement cost). We tried to install an OEM bearing, and it didn't fit! We had to replace the hub with an OEM one as well. Just another story of the risks of cheap parts.
