Re: Genuine Ford Parts

Mr GT,
Seeking your knowledge to help understand something.
F3LY3B477A is the old black pacnut for the front AU/BA/BF hubs.
BA5N042A is the current black pacut to secure the hubs on sedans and Territorys.
Ford specify the rear nuts are single use. And obviously a different part number means a different part.
But I can't see any difference between the 2 parts, apart from the rear was about $20 more than the front. Same measurements, look the same. The rear one holds a slightly higher torque.
Do you know what is the difference between front and rear? And what makes the rear nut single use but not the front?
Cheers.
