Washing Machine not spinning; grinding noise

Hello DIYers!

So have this LG WM2487HWMA washing machine (link) starts, draws water, but does not spin. Instead, there's a grinding noise you can view here:

I disassembled the rear and here are the photos. Notice there appears be some rust-colored residue that can be wiped up but wanted to see if I can get your input on what it is. The motor itself is still under warranty so would it be justified to get a replacement? Others who have posted similar have shown the same parts very clean so not sure what to make of this residue but let me know what you think.






I still haven't tested which part needs replacement.

I don't work on many LG machines.
Your problem looks like a defective tub seal.
An involved job..... not hard just time consuming.

This should be the video. Check it out...... replacing tub seal video

I use Sears Parts Direct for exploded/parts views...... LG washer

PJmax I'm stuck on a single screw that holds the stator in place. It's a hex bolt that's been stripped. The other ones were a pain to remove but I got them out. This one I'll have to drill them get new replacements on all of them. Still haven't been able to test any part yet, but I'll continue that video when I get passed it.

So I disassembled the damn thing. Here's a photo of me when I was done:



LOL

Anyways, it doesn't appear that any of the bearings are damaged. Take a look at some photos:




What is noticeable is the calcium buildup around the parts. Should I scrub it off? I have some of that Calcium Lime Rust remover.

But let me know what you think about the bearings.

Bearings spin just fine. No friction or sound. Not sure what changing them would do. They're kind of costly so I'd rather avoid changing them if I can, but since i made it this far, not sure if I should just change them for the sake of preventative maintenence.

Have my washer bearings failed?

Disassembled the washer and there's a little bit of a racking noise when the machine is spinning, not sure if that's the bearing failing exactly? It does appear to be turning evenly and with minimal effort:

I watch the tub spin and the center isn't moving but it looks like the tub is wobbling on the right side.

That grunge all over the back of the tub and rotor is from the tub seal leaking.
I left that video because you need a tub seal. It keeps the water out of the bearings.
Since the bearings have been running in water...,. I'd replace them both.
Search the part numbers for the lowest prices. I'm seeing $50-$75 for all 3.

That's a great point. Thanks for clarifying. I'll order those parts then.

What about the rust / buildup on the chassis / thermal rods? Shoukd I clean that off?

You can use a wire brush to clean rust.
A rust remover and a rag is ok too.
A little PB Blaster would be good.

Alright, reassembled it and changed the drain pump. It's working good!
