the problem indicates that the air dampeners on the ends of the support rods for the tub have failed

A couple of ideas.
First, type in your model number to the web-site named: "SearsPartsDirect".
The schematics will show whether you have a drive belt on that model.
If there is, that belt may be slipping, or worn out.
Before you order a belt, consider this.
If the machine is not properly spinning out the water on the spin cycle, ( for example, if the belt were loose), then too much water may overload the machine causing your problem.
God bless your efforts.
