Still chasing the rear steer wobble. Slop in between collar and housing

From doing the same chase on my 04, which uses the same suspension, I found play in between the shaft and the swingarm inner bushings. I found it on my old parts, my new parts, and every swingarm assembly I found at swap meets. You could make your own inner bearing bushings I've you've a lathe, or you could use shim stock, which is what I did. On my bike, with all new parts, mounted up, but the belt not tight, there was about 1/8" slop at the rear wheel because of that inner bushing to shaft slop. A tight belt masks this.
I do not agree with the notion that the shaft is supposed to be tight in the transmission housing, for this is where you make the alignment adjustments for the two pulleys. That hole is not precisely drilled, and you use the engine alignment turnbuckles to bring the pulley's into alignment.
The frame bushings are not round or true, by design. They are oriented to place the axle in a specific spot. These are fairly precise, and are a bunch of steel discs that are rubber coated, it is not a monolithic block of rubber.

The problem I've found is that the aluminum is soft and the hole about 0.755-0.758. Like you say the bushings that are pressed into the bearings are also loose.
Add: The rubber bushings are offset to help with thrust of the drivetrain on the frame.. FWIW, glidepro polys are centered.

This thread has thinking. I'm planning to do something with my 02, it doesn't have the death wobble but instead if I brake (rear) hard or do a hard burn out, rear of bike goes to the right.
I'm planning on a true track stabilizer for the rear and revisiting alignment. I thought these bearing's in the swing arm was supposed to be way better than my 99 but something can be off from what I'm reading here.
The trans shouldn't matter if there is slop, my thinking because when you bolt it all together it gets sandwiched into one spot once torqued.
