Okay po ba yung Koyo brand ng wheel bearings as replacement sa Toyota OEM?

May umuugong na po kasi sa likod kapag mabilis yung takbo. I was also informed na talamak yung counterfeit wheel bearings sa market. Is there anyway to determine genuine from counterfeit Koyo wheel bearings?

Naginquire sa isang online seller na Koyo brand, he priced it at around php1100 for the front and Php3850 for the rear since it's a wheel hub bearing with ABS sensor so I suppose ito nagpamahal sa kanya aside sa hindi siya pede irepack. This is for 2nd gen vios.

Reasonable na po ba yung naging pricing? If ever may alam kayo reputable store na nabibilhan at naginstall?
