Suntour 7 Speed Freehub,Freewheel or Both?

I have been going through my wheel collection which is too large and mostly low end.
Wheels from a GT mtb I think. Not enough majic, front is not going to buff out. Broke while I was washing it using a scrub brush.

Rear is a 7 speed, FH date code so Aug 1989. Some type of mashup of a freewheel & freehub. 135 spacing. NDS seal is Sansin.

NDS has 13, 3/16’’ balls. DS has 12, 1/4’’ balls I think. How do the DS balls come out?

Identification and direction on servicing much appreciated.

The rear had a slight hop when I was checking it and was not adjusted properly. I had trouble getting it smooth, seemed tight each rotation so I took it apart to see what’s up. It’s not pitted so far but waiting to get behind the DS balls.

Are the splines on the back of the (freewheel?) cogs permanent?

What are the symptoms of a bent axle? The axle seems to roll smoothly across the top of my bench.
