So I have an 04 new body style FX4, with the 3.73 9.75 rear diff, and obviously 5.4 triton. I see their is a 107, and 120 front hub assembly. I assume I have the 120, as it is the heavy tow package,but I am not sure? Anyone know? Also is it worth paying more for the Motorcraft hubs, or are the Timkin or any other aftermarket brands as good or better? I was planning on the Motorcraft 120's, which seem to be cheapest on Amazon. Advice?
