Product review (2 stars): Before you buy Suspension Rods!
Before you buy these, a few considerations:  If the drum is not banging around too much, and you get the UL warning at the same time in every wash (usually at the beginning of the spin cycle) your problem is probably NOT the suspension rods!  Check to see if the drum spins freely - if it is catching at some part of it's rotation, you either need to clean the stator assembly, or you need to lubricate or replace the bearings.
