axel nut

[dogman]

I'm going to replace my lower ball joints on my 2006 expedition. Does anyone know the size of the axel nut its 4 wheel drive. what are the odds that the upper ball joint would need replacing at the same time? Thanks

Can't answer the nut question off the top of my head. But put the front up on jack stands, get a 4' pry bar and see if there is movement in the ball joints.
