Hello:

Have the fairly typical Sears Kenmore electric dryer whic is close to ten
years old by now. Model is 110.68089 11

One of the drum support rollers has gone bad, and thought I would replace
it myself, as the roller part is relatively cheap.

Question: Even though there's probably enough room for me to reach the
roller which
is at the rear of the unit thru the kick-plate door from the front, I was
wondering what happens when I remove the roller ?

e.g., Will the drum fall down ?

Should I block up the drum with some wood prior to removing this
roller ?

How is this kind of repair normally handled; any caveats or "gotchas" to be
aware of ?

Thanks,
B.
