YES!
Fridge,
We're Maxima buddies and I'm having a similar situation with my 5100.
But I was afraid to say anything out of fear of the "YOU SHOULDA BOUGHT A SPEED QUEEN!" crowd.
Anyway:
That's what always amazed me about these machines!
When they would go into spin, everything would be amazingly balanced 99% of the time, even big heavy towels.
I've touted how amazing the balance was when it was brand new, and after the "awkward phase" of the basket swinging around in ramp-up, it would distribute out and there would be NO tub oscillation during the rest of the spin speeds. NONE. The basket was steady. Even at 1400 rpm with zero vibration.
I LOVED it. Even on my 2nd floor location.
However....
Several months ago there was "an incident."
I had a load of mixed shirts going, and it was in spin while I just watched TV.
Then all of a sudden I heard a loud rumbling coming from the Maxima.
It shut itself down and ended the cycle, likely because there was only 2min. left. But there were NO error codes.
After that "incident" the spins were never that smooth again.
It still operated almost great, but spins were now vibration prone and the tub would always oscillate slightly in spin. Never holding steady like it used to.
I for sure thought something broke.
So I initiated my Home Depot protection plan and had a [really great and knowledgeable] WP tech come out to look at it.
He looked at it and ran some test spins both empty and with wet towels.
However he refused to open it because it's a stacked unit (ughhhh, they need two people).
The tech said it vibrated a bit but it was all within normal parameters and there's nothing he found wrong with it.
Of course I got curious so I opened up the back on my own.
I inspected the struts (fronts were hard to see but they looked fine). However the rear right felt looser than the rear left, so I swapped their cylinders, and redistributed the grease on the friction pads.
That SEEMS to have every so SLIGHTLY alleviated it, but that won't last long.
But....What's curious is the area of spin it has the most oscillation and vibration is in the area where the struts are "free floating" anyway!
These struts allow about .75" of free play, whereas it's likely expected the ball bearing balance rings are supposed to smooth out the rest.
But they don't seem to be!
And I cannot notice any evidence of the balance rings being out of sorts.... I do not notice any bearing noise or basket movement out of round with the tub...
So....I've just been dealing with it. Dealing with longer spin times, and more vibration. It doesn't go into full tilt 1400rpm as much anymore, but it still will.
I'm just waiting for something to fully implode so HD will actually repair or replace it.
