I have a 05 F350 Dually 4x4 6.0 with a 4.10 LS And I need help finding the outter wheel bearing the one napa list is to small and for wants $270 a bearing the number on the bearing is TIMKEN NP 678813

 

Sorry to dig up an old thread, but I found this post while trying to find this exact bearing. I spent hours calling different suppliers and cross referencing numbers. Autozone sells an exact Timken bearing with a different part number #39250 and its about $30. Apparently, the old Timken part# NP678813 defers to dealer only. FoMoCo part # is 5c3z1201A and it comes with the race. Lists around $80. Hopefully, this helps someone out...
