Kenmore Washer Model #110-44182400 making loud grinding noise during washing cycle?

SOURCE: Kenmore wont agitate or spin

Mindurrs, your motor coupling has gone to the great beyond. Time for mourning has passed and now it must be replaced. The job takes about an hour and parts run about $10.00, ready? First, go to your local appliance parts retailer and purchase a coupling, part #285753. You'll need this for repairs. UNPLUG THE WASHER!!! Standing in front of the washer, you'll see two screws on either side of the control panel... remove these then flip the control panel over. Now, toward the right side, you'll see a wire harness that plugs into the top of the top panel, disconnect this. Now, on either side of the top panel, you'll see two brass colored clips. Take a screwdriver and poke it into the hole, use it as a pry bar. Pry the handle of the screwdriver toward the wall behind the washer, the clip will pop out. Now tilt the entire cabinet of the washer toward you to about a 45 degree angle then lift it out of there and set it aside out of the way for now. OK, now we're into the guts of the washer... Look below and in the center, you'll see the drain pump (it has 2 big hoses attached). Behind that, you'll see the motor... that's what you'll be taking off. On the right side of the motor, you'll see the electrical connections. Remove the long white one from the motor. (CAUTION!!! THIS NEXT STEP MUST BE DONE, OTHERWISE PERSONAL INJURY MAY RESULT!!!) You'll see a black round thing mounted to the motor on the right hand side, this is the capacitor. It has 2 red wires on it. (It's basically a 120 volt battery that is just waiting for you to touch it so it can shock you, badly) THIS MUST BE DISCHARGED (voltage drained off) BEFORE CONTINUING. Remove the 2 wires using insulated needle nose pliers. Now, discharge the cap by touching both terminals of the cap at the same time with your needle nose pliers. This will discharge the capacitor so it's safe to handle. Now, above and below the motor, you'll see 2 clips mounted on it, remove the screws that keep these clips in place then (with a flat head screwdriver) pry the clips off the motor. The motor and pump will drop out of there. Rotate the whole thing off to the left (with the hoses still attached to the pump). Now you can see the broken coupling (compare the old one and the new one). Pry the old pieces off the motor shaft and the transmission shaft and throw 'em away. Install the new coupling (notice the semi-triangular shape of the inside of the plastic coupling? I use my screwdriver handle... poke the handle into the coupling, place the coupling squarely on the shaft, then tap [don't BANG] it home with a hammer) and rebuild in the reverse order of dis-assembly! Sounds complicated, but it's not. I've done a thousand of these and it took me longer to type this than it would have for me to do it for you! And, for what it's worth, you have a good washer there. It's actually made by Whirlpool, and well worth the repair.

SOURCE: kenmore series 80 washer makes loud knocking noise during spin cy

Unless your front loader is set firmly on concrete and leveled to perfection, the force of a heavy wash load spinning in excess of 1000rpm will create a bit of vibration and noise.A firm footing is your best defense against to much movement.
Also due to the earlier movements during the spin cycle, the shocks that are used to dampen the spin cycle might have been broken or damaged.
If the problem persists inspite of proper levelling, please do check for the shocks or might have them replaced them for good.
