It is critical to make sure you get the hub nut TORQUED properly .It will make a difference on how long the new bearing will last . Do you know positively if your torque wrench is accurate ? I could not get mine set right so I took it to a local shop and they did it for me free of charge . They told me they send their wrenches in and have them set every so often .. So I trust they were torqued right. I have a buddy that dont believe in torque , he thinks the impact will do the job . Sorry, not with hub nuts . Have fun and stay away from Ford Dealers for repairs . PS;dont know how check your torque wrench ? Do a search and you will see three different types of torque wrenches . Harbor freight also has a attachment for your socket wrench in digital read out for torqueing ,I think its $35 bucks .
