Product review (5 stars): Excellent quality product
Excellent quality product, washer never ran this quiet and vibration free.  Service and technical support is equally outstanding.  Instructional videos make it easy, using old bearings to install new ones is ingenious in its simplicity and effectiveness.

Background:  We have a Whirlpool Duet Washer model GHW 9250.  The arms and base that attaches the inner metal wash drum to the shaft had rotted away.  Bearings were also shot.  This is after 11 years of use.  Whirlpool warranties the wash drum for life!  So for $120 (bearings, couple of tools, sealants and gasket) we now have what is essentially a brand new washer, should easily last another ten years or more.  Sure beats spending a $1000 plus for a new washer.

Hints:  It's an involved dis-assembly/assembly process.  Not difficult, just involved.  Bag and label hardware as you disassemble.  Write a numbered list of major dis-assembly tasks.  Then just reverse for assembly.  Takes lots of photos, especially of spring locations.  Mark everything, we also marked location of drum clips.  All this made re-assembly a breeze.  (Also, there are YouTube videos on removing the drum.)
