We have an older Duet washer.
It is about 10 years old.

It performs well except gradually over time it shakes more.
It seems that the shocks have worn out.
The unit bounces around a lot during spin cycle and after reading the recommendations & repair guidance on this site it appears to need new shocks.

Cost would be a bit over $200 in parts and shipping and then some time.

I'm happy to put several hundred dollars into this machine but given that it is 10 years old have to ask:

Are there other parts on this machine that could fail soon that are no longer available?
What are they and what's the risk of that being the downfall of the machine?
How can I check the health of any parts that might not be replaceable in the near future due to a lack of availability?

Thanks
