LG Dryer Vibration

[JBond]

So now my LG DLG2522W Dryer is vibrating, I guess it wants to match my LG washer. I imagine it is the rollers that are going out and from the drawings I have found it looks like there are actually 4 but the LG parts list says 2. Anyone know how many I need to order and if in fact that will fix the vibration? (Standard install on concrete floor.)

The diagram shows there to be 4 rollers, 2 in front and 2 in back of the drum.

Any unusual vibration would be from them or also from the blower impeller. If it is worn or clogged, it can spin off-balance, causing a shudder during operatoin.

The dryer vibration is most likely from debris on the blower wheel--a fabric softener sheet/excessive sticky lint caused by fab softener sheets or clothing such as a sock. When this occurs--the blower wheel wobbles from the imbalance caused by debris.
Removing the debris from the blower wheel solves this problem.
