Differential still runs rough

[Braunschweiger]

I posted this in my construction threat,
I hope I get more attention here, thank you.
Actually, I just wanted to replace my broken pinion yoke, the connection ran to the side and wasn't routed cleanly and because I also have humming noises, I got one straight away Overhaul kit for the differential obtained.
The differential has already been overhauled.
The differential also came out of the housing very easily, which surprised me.
The bearing behind the yoke on the pinion was broken, all other bearings were undamaged and ran smoothly.
The pinion was reassembled with a new crush Sleeve and Yoke, the crush Sleeve was broken and the preload was set at 19 inch pounds, a silly job under the truck.
But the beam has an axial clearance of 0.20 mm (0.00787 inch), which is way too much, it is supposed to have a preload of 0.010, and the Backlash is also too large at 0.45 (0.0177 inch). .
I first ordered shims for the carrier and a solid spacer for the Pinion and will probably have to readjust these. I'm not satisfied yet, I also picked up the overhauled drive shaft today and put everything together.
I did a test drive and found that the differential was running rough.
From 55-60 ml it is quiet. I need some advice from you.
What did I do: The pinion got new bearings and was assembled with a solid spacer and reached 19in-ibs as preload and the carrier also got new bearings,
the Backlash was set at 0.009 inches.
I thought the stock image was fine.
It's an 8.5 10-bolt axle with 2.41:1 locking from 1978.
I would be happy if you could help me with this, thank you.

P.S Here are the pictures from Drive and Coast
