Kenmore Stackable Unit Washer Tub Wobbly/Loose 417.97812700

The inner tub is very wobbly/loose and I need to know what part needs to be replaced.
I originally thought it was the Trunion (p/n 13154501) upper piece was broken until I looked at the part online and it's not broken.
When I use the spin cycle with a medium/heavy load it won't spin, the drive motor pulley runs but belt doesn't turn. However, I can turn the Transmission Pulley manually CCW and the tub rotates.

Check the belt and the idler pulley & spring.

Pull the agitator and make sure the plate bolted to the trunion is lined up with the flat spot on the shaft from the transmission and tight.

PS - would be handy to have spare bolts if you have to remove them, I've broken them easily.

I replaced the Tub Seal, Trunnion, Block and Screws but I cannot line up the bottom frame with cabinet to install the screws (total of 7 - 3 on each side and 1 in the back).
Therefore, I need instructions (or video) to assist me.

Only time I had the cabinet off it lined back up easily...  beats me...

This is a Kenmore Laundry Center (Stackable Unit made by Frigidaire) and I had to remove the Base from the Cabinet so I could remove the Inner Basket to replace Upper Tub Seal & Trunnion.
[/size]Service Manual said to slide the Base out far enough to remove the Inner Tub so I assumed the procedure would be reversed but the Cabinet is not seated properly on the Base (aka Bottom Frame) to install the screws (total of 7).[/color]
[/size]I tried using a 1-2 inch board to raise the Cabinet but that didn't work. Could the rear legs on the Base possibly cause the problem.[/color]

I've never taken the cabinet off to do that job.  Maybe line up one of the screw holes with an ice pick.  Once you have one lined up, you should be able to get the other screws started.

I'll give it a try and update my results when this issue is resolved.

I was doing a 'store stock' with plenty of room replacing the base plate. Laid the whole thing on it's back after taking the tub out...
