I have a Sears Kenmore (mfd by Whirlpool) Dryer, model 110.64212200 that
is almost 3 years old and only gets light/moderate use. It has begun
making an unhappy squeaking/groaning noise during operation. Based on
the frequency of the squeaking it sounds like it is the drum rotating
that is causing the squeaks, not the motor.

Is there anything that I can lubricate or otherwise do to maintain my
equipment? The user manual and installation manual don't offer anything
of value other than the parts diagram.

Thanks to all for the advice! Looking thru my parts list and poking
around online, I found Part # 279948 [Dryer Repair Kit] which Whirlpool
apparently has replaced with Part # 4392065. The dryer kits are matched
by cabinet size, and this number matches my cabinet width of 29 inches.
Sears Parts sells this item for $30.77 plus all of their fees
($29.99 at Whirlpool's site] and I've found it elsewhere for even less.

It looks like they have a do-it-yourself guide as well, perhaps this
would be useful.

I'll be tackling this as soon as I get the chance, it doesn't sound too
bad.
