Product review (5 stars): Saved a bundle on the repair.
I had the bearings & seal replaced less than a year ago but because the shaft on the old spider unit was scored the seal failed soon and the water took out the new bearings again. Bought this and new a new bearing/seal kit this time and did it myself. Saved a bundle on the repair over having the repairman. Seems to be at least as good as the original. Worked really well.
