Hey everyone. I'm in dire need of some good help. I have a 2004 F150 FX4 with 9.75" rear diff. I have a right rear axle that is bent, but I'm not sure which one I need to get. Everywhere I look shows the 2004 F150 with the 9.75 to have 5 studs, but mine has 6. All the 2005 trucks are correct though. I found ProKing Differentials page and found the part number for what it says I need but I don't trust it because the picture has 5 studs and it doesn't specify if it has 5 or 6. Like I say, my truck is a 2004 with the 9.75 rear end, and I need a right rear axle shaft for it. If ANYONE could help that would be great. I need to get one within the next few days.

 

A 2004 F-150 "Heritage Edition" would have 5 studs. It's basically a 1997 - 2003 truck. A regular 2004 F-150 is the newer body style and will have 6 lugs.

 

I knew that. I think I'm gonna get one from Summit. It's 6x135 and fits the 9.75 rear end
