Differential is easy to inspect. Or maybe you have a smoked bearing. Did you check all bearings when you had it apart?

If the issues was differential or final drives,wheel issues the noise would be in all gears correct?

The noise I hear in yours sounds like one mine is doing. Not sure what it is but it is getting a different trans at DSCF this year.

There are two ways to get enough Cubs. One is to continue to accumulate more and more. The other is to desire less.

Spilt the tractor to replace the shifter fork and rail, and replace the bearings and seals on the top shaft..
Noise is still predominantly 1st and 2nd...3rd runs very smooth..
Lower shaft?

It was suggested to me that the noise in mine was from the forks being misaligned or worn.
You’ve said yours was weld repaired.
Perhaps it looks right but is off just a hair causing this problem. Can you get your hands on another cub to borrow the shifter an forks from?
Install a known to be good set and see what happens. If it runs quiet it’ll save you a lot of work.
