Replaced agitator coupler...and seal tub...used youtube for directions through appliancepro.com...all instructions great...RECOMMEND MUST have the spanner wrench or tub nut wrench...no can do with any other tool in your arsenal. That is unless you have a 3/4" socket set with 2' extension. All parts as advertised and delivered on time. Kudos to AppliancePartsPros.com.
