Rear axle wheel bearings

Hello, At 120000km a wheel bearing at the rear left side has become loud. Are the wheel bearings at the front side the same? In my opinion, changing each axle would be advisable or does it have a different opinion or view?!? Have you picked this out: https://www.lott.de/…/skf-rad bearing set-ww1844231?… Or should I switch to original? Please give us a short info Your regards:
