White lithium safe to lubricate a dryer?
I think you have or had same problem I am having which is not a bearing at all. It is the glides (small plastic strips) that the outter drum rides on have either dried out or in my case 1 is missing.

I came here looking for the same answer you were about the silicone due to the amount of time it takes to deliver parts and the fact that the family is going crazy.
