Front loader washing machine shaking/vibrations

I've been struggling with some shaking/vibration problems with my Whirlpool Duet front loader washing machine. I believe the main problem is the floor isn't sturdy enough as it tends to shake quite a bit, especially during the high spin cycle, but I'm wondering if there may also be a problem with the washer itself.

Here's a video I've filmed. Some washes the vibrations are worse with it sounding and reacting like a jack hammer:

The washing machine is perfectly level and all four feet are firmly planted to the floor. It doesn't rock at all when you push on the four corners, so it's either a problem with the washer or the floor or a combination.

Thanks for any help.

Is that spinning an empty drum?

Could be bad bearings. Try grabbing the rim of the inner stainless drum with both hands and rocking it sharply side-to-side or up-down to see if it seems loose or wobbles the outer tub. The entire assembly will of course oscillate on the suspension springs and shocks ... but if the inner drum is obviously loose or wiggles inside the tub, that's a sign of bearings worn.

The drum support (aka spider), which is a 3-armed cast aluminum piece to which the drum attaches (the drive shaft is part of the support) can deteriorate and crack on one (or more) arms, which throws the drum slightly off-kilter during high-speed spin. It's an obvious, very catastrophic failure if the drum breaks completely loose from the support during spin, or if two of the three arms are cracked.

Nope, the drum is loaded. I'd say a medium to medium-heavy load of mixed fabrics.

I've regularly pushed the drum side to side and up and down and it seems normal. Doesn't seem loose nor is it bumping against the sides or anything.

Maybe a broken/bad shock.

Does it rattle when spinning empty at maximum speed? I refurbished a 5+ years old Duet 9400 recently that had bad bearings. The drums are manufactured balanced pretty well but not necessarily 100% perfect so there may be a smidgeon of vibration even when empty, but much less than when loaded. Worn bearings were obvious by rattling when it got up to full speed, along with looseness of the inner drum.

I haven't ran it empty, I'll have to try that.

That sounds like my sisters Kenmore making the same rattle as if they were a TL'r belt drive machine and her's is on a double joist foundation.

I would think one of the shocks are worn!

Is it level, and does each corner carry equal weight?

Yes, as I mentioned in my post, it is level with all four feet firmly planted on the floor. It does not rock when you push on the corners.

IF the problem isn't with a defect in the machine and you are convinced it's the floor, put two layers of 1-1/8" Sturd-I-floor under the equipment. Screw two panels together before installing on a FLAT floor. That will effectively make the equipment "think" it's sitting on concrete. If the floor ISN'T totally flat, use a floor leveling compound prior to setting down the Sturd-I-floor. available at Home Depot.

NOTE: if there is an issue with the equipment, fixing a flimsy floor isn't going to help. good luck
