Product review (5 stars): Easy install on Whilrpool HE front loader
Installed all four shocks in about 15 minutes.  Removed back cover about 8 screws and front cover 3 screws.  Used channel locks to twist/break old ones out, new ones easily twist locked in.  Repairman wanted wanted $250.  If you are a girly man and don't own channelocks or know what they are you may want to hire a repair man.

Unit was vibrating badly after about 4 years of use becuase the females who live with me were overloading the unit with 20 pairs of jeans and/or every towel in the house.  They break em we fix em, a whole other story only understood by the male species. I releveled unit, adjustable feet which if out of level can cause vibration.  This did not cure the problem, opened back of unit and found one shock broke.  Figured others are past thier lifespan and installed 4 new shocks.  Releveled unit and it no longer vibrates around the laundry room, runs as smooth as new.
