I changed three main tires on aircraft that night. [I] had the work card with me. I just got complacent and just made sure the Number-4 tire had the inner bearing on and didn't look at the outer [bearing] on. I must have gotten two inner [bearings] from [Parts] stock. Upon landing; the brake seemed to fade in ZZZ1; [so Maintenance] took off the wheel and found that two inner bearings were installed [at the outer bearing position]. I was complacent and didn't make sure the outer bearing was the outer bearing. The one from stock wasn't an outer bearing. Not really sure; I think the Main Landing Gear (MLG) Shock Strut was changed; the tire was [replaced]. Was my fault; I need to take my time and look at both bearings. Aircraft damage.
An Aircraft Maintenance Technician (AMT) was informed he had installed an inner wheel bearing at the outer wheel bearing position for # 4 Main tire on a DHC-8 aircraft. Brakes seemed to fade upon landing after Mechanic had replaced three main tires.
