Product review (5 stars): Also Replaces Kenmore Elite HE3 Baffles: Instructions included in review. Cheers!
This does replace the Kenmore Elite HE3 line as well.
Pretty easy DIY

If you have the older style that don't match these.
Replace all three to keep the machine in balance.

Three screws in the back hold the top panel on.
Pull it off and remove the hose from the top side of the drum.
Rotate the drum until you can see the screw through the hole where you removed the hose.
Use a good magnetic bit to remove the screw and change out each baffle.
Simple rotate repeat and attach the hose and replace the top cover, and you are ready to tumble again.
