Axle Replacement, 1 or 2?, DIY or shop??

[NHdigger]

One tire on my AS is totally shot. Hit a curb last year after a truck cut me off.
Checked bearings- good
Checked brakes- OK not dragging, releasing fine
Alignment- out 5/16" with rear tire (thanks Howie E)

Is it possible that the axle shifted that much in the slotted bracket to cause the problem or is it more likely bent?

If it is the axle I spoke with Colin Hyde and have several options:
replace 1 axle, replace 2 axles(normally done ), replace with good used axle(quickest option).
I am leaning toward just 1 new axle since the AS only has approx. 10K miles and shouldn't need axles for a while.
Now for the tricky part. How hard is it to replace myself? Looks like a lot of grunt work, not technically difficult.
I only see 4 bolts holding the axle to the frame with a slotted bracket. Alignment ?

1) If the axle is damaged the most likely the spindle is bent.
2) If the axle mount is bent you are in for some excitement.

DIY axle replacement has been done by many people if not hundreds of users. So you are correct it isn't tricky. Typically the most difficult part is removing fasteners. (Shoot with penetrating oil days in advance) No alignment typically needed unless #2 applies.

If you order from Colin make sure you have the manufacturer weld in studs for the shocks. I helped a friend do this job today and we had to remove the old shock studs and weld them to the new brackets. They should have come from the axle factory this way.
