Product review (4 stars): Great price, just be aware that W10350376 is different than W10350375 only by the shape and size of the wheels
Love that the price is reasonable for this part, $14 at the time.  Just be aware that my Whirlpool Gold WDT790SLYM had all three model numbers written on the original broken part (W10350374 W10350375 W10350376).  I ordered this one because it was cheapest and I couldn't find a difference between all 3 numbers.  However now that I just received the item and installed it I found the difference for my model to be the rolling wheels.  I was able to take off the 2 original white wheels and easily place them on this item but have found that they don't 'roll' like the opposite side of the top rack.  Rather they hold in place and slide on the rail.  Overall it does work and I'm not sure if the 'rolling' white wheels is intended or just from 2 year usage and getting loose.  So overall satisfied but if you don't have the original wheels or have broken ones, then go for the W10350375 one, which I believe according to pictures is the right wheels for this model number.
