I installed Steady Fast front and rear. We have Splendite stacked washer/dryer They cut down wobble when the washer spins. Did not completely eliminate the shaking, probably about 95%. Rear installed with no problems They do not have to be exactly square to the frame. On mine running from curb side jack to street side frame the locking mechanism is about 6 / 8 inches behind the jack. Paul ( the owner of Steadyfast ) is real helpful if you have problems.
