Tub seal part number? How to replace?

I have the Kenmore front loader washer. It has been leaking a little, so I opened the panel under the door. No water in the beginning, start to leak towards just before the spin cycle started…or around that time.

It appears to be leaking where the outer tub halves come together.
I’m not sure what the part # is, and the best way to go about repairing it? Ie the steps to do it.

Any other parts i should replace while i’m there? I’m thinking of doing the shock absorbers at the same time.

thanks!

Has anyone attempted this seal replacement? Aside from following the steps in the manual, are there any tricky spots such as getting back in the door seal? I don’t mind a long length of steps and time…but if there any difficult spots, I would like to know in advance.

Thanks!
