Product review (3 stars): CAUTION: Double check and check again your part number!
If you arrived here to buy this WD12X10277 lower dishwasher stud by having done a search for part number 151B9538, double check and check again your actual part number. I used the search term "151B9538" because that's the number imprinted on my dishwasher wheel. This WD12X10277 lower dishwasher stud is the only result that returned. So I ordered it. It's not the one I need. Not worth the postage to return it since I only paid $1.95 for it. But just saying... check, double check and check again your part number.
