Dana 80 axle assembly

New to diesel and also the forum.
1999 F450 7.3 2WD DANA 80 with 4:88 10 bolt with 19.5 tires 201k.



Leaking axle seal




Everything else looked fine from what I could see.



Howling in the drive train only when accelerating. Over 15mph if I'm on the accelerator I hear the noise.
Popped open the differential cover and see chipped teeth on the ring gear (possibly failed bearing).
The question is "should I rebuild or replace the entire axle assembly? "
I was told by Ford that the carrier housing could also be damaged and i also have to replace axle seals and bearings.

I would replace it. The cost would probably be similar either way. You can possibly find a later model setup that will bolt in with no issues.
