Front load spin out of balance

While spinning, tub hits side of machine casing. Load size does not matter. As best I can tell, all four shocks (?) and the two springs are ok.

Any ideas???

After running the spin cycle via diagnostics control, I discovered the round aluminum flywheel(?) on the back of the tub is the culprit. It is out of balance almost to the point of the belt coming off.

How easy, expensive, economical is it to repair this? Is it actually the flywheel or the shaft on which it resides?

Thanks,
Ray

hello? Any advice?

Replaced pully and belt and problem is solved. Sadly, this made me aware of another issue. The tub is out of balance just enough to make a slight knocking noise. If I push the tub back away from the front of the washer just a bit, it stops.

How do I make an adjustment to the tub position to move it back?

When you spin the tub by hand, can you hear bearings?
