I will say that I pulled the passenger side for good measure.

I am a believer in symmetrical maintenance, even down to light bulbs (if the LH headlight blows, I change the RH on principle).

The grease on the RH outer bearing had already gotten some discoloration so this one was on borrowed time too. Spindle still looks pristine so just a basic bearing replacement required on the right.
