Hi I have a 57 GMC 1/2 ton pickup and i am currently tearing apart the front end. Im doing a complete overhaul of the systems and i was just wondering is it really worth it to convert from ball bearings to tapered roller bearings? I am sticking with front drum brakes and the only thing that iplan on changing with the brakes is putting in power brakes. I know that the roller ones are a little more expensive but if its necessary than i'll pay. Any ideas?
