You may have better luck with a used EBay or pull a part oem Subaru starter. Remans are hit or miss and usually very inferior quality compared to oem. Does Denso make the Subaru starter motor?

I’ve never had an issue with a starter on any of my vehicles so I don’t know if other aftermarket starters like Bosch are any good.

The oem Subaru is expensive but it will last for a long time.

Subaru does sell individual parts for the starter motor. Not sure if the brush holder includes the carbon brushes. Why can’t Subaru use a brushless motor design?

Brushless motors have been around for a while. I don’t know if brushless starters are a thing. But it would be a good upgrade if it was possible.
Here’s a good web store for starter and alternator parts. If my starter went bad, I would try to rebuild it myself.
