Use this guide to replace the drum roller assembly (drum rollers and roller shafts) on your Whirlpool Duet WED87HED dryer.
The drum rollers serve as the bearings for the drum so that it tumbles freely. When they wear out or fail, they will make a rumbling or squeaking noise. The noise will be fairly loud, as the drum roller shafts are strongly mounted to the chassis of the dryer.
The drum rollers are best replaced as a set. If one has worn out, there's a good chance that the others will follow since they all have bearings in them.
Check the drum roller shafts for wear when you are replacing each roller. If you see wear marks but cannot feel a groove with your fingernail or fingertip on the shaft, it's probably still serviceable. The shafts only require replacement if they're damaged. You will need a 3/8 drive 5/8 inch size socket and the 3/8 drive socket wrench if this is the case.
