Front axle - are you able to keep the donor axles brake hoses and hard lines and simply connect the center brake hose from your vehicle? Or did you use the center brake hose on the donor axle? or some other scenario?

thank you

It's in the thread...but in short, you have to bend the "extra" hard line from the leaf front to fit the new mounting positions for the flex line on the coil axle. On the coil axle the flex line mounts to the coil spring bucket...on the leaf front the line goes to the tab on the top edge of the frame.

Yup, bend your existing line from behind the coil around to the front.

Maybe a dumb question - Are the front coils fastened in any way at the top or bottom?

I don't see anything in the online Ford parts diagrams. There is the rubber insulator at the top and then it looks like it simply fits into the metal support at the bottom.

You are correct. With the sway bar and shock attached, the axle cannot travel far enough to let the spring escape it's capture points (spring perch on axle and isolator at top) at top and bottom.

What if the sway bar is removed? Will this pose a problem?

I would not want JUST the shock holding my axle at full droop and keeping my springs from popping out. The shock isn't designed for anything close to that kind of duty. If you don't do any off-road stuff, this might not be a concern at all. Once you get past full droop, your drag link and track bar are all that is left to hold the axle "up", but the springs fall out before that happens.

I am in the middle of this swap as well, although mine is slightly more involved. (5.9 cummins and zf-6 manual transmission swap at the same time. Just some input for the guys worried about brake lines, you can go buy a roll of 5/16" nicopp brake tubing (all of the lines that I have seen, at least on 04-07 trucks) are 5/16) and a cheap bubble OR double flare tool, and make your own. Just re-use whatever fittings are on your truck and the donor master cylinder. The tubing is super easy to work with.
