Product review (4 stars): The washer design does not provide tub bearing seats. ...
The washer design does not provide tub bearing seats. To get around this deficiency, the offset action of a special assembly tool on the tub bottom eliminates the need for one bearing seat while a special spacer tube effectively creates the seat for the upper bearing AFTER the lower bearing has been successfully seated by the tool during the overall assembly process. The problem with this approach is ease in which the spacer tube can be damaged due to unfamiliarity with the whole assembly approach. This can be corrected with clearer installation instructions and attention to bearing travel during the overall assembly process. In my opinion, the damage is.caused by inadequate wall thickness of the spacer tube, which allows over travel on both bearings to crush it. So care must be taken to ensure that the tool does not cause bearing over travel during the bearing assembly process. The whole concept works, but some mechanical skill and attention to detail is clearly necessary.
