Fit perfectly, working great.
Fits petfect, working great, just like the original product. Be careful to make sure it clicks very well into place! That's the reason I had to buy, I was cleaning the machine and accidentally didn't get it clicked into place well enough and it hopped off and got melted on the drying cycle. So glad for the easy search for parts through partselect as they always come through for me when I fix appliances in my home.

Easy repair, part overpriced
How a clip broke off the old one remains a mystery but this part is over priced. I also considered wheels for the lower rack until I realized it was $52 x4 = $208, I’ve been gorilla glueing those back on for years.

Part 26. We have found yellow plastic track pieces with little tiny stainless roll balls in the bottom off dishwasher. This is the only part we can figures where it came from. Is this possible? Some of our dishes/glasses are not getting cleaned anymore.
For model number MDB8969SDM0
Hello Laurel, Thank you for your inquiry. The stainless ball bearings are most likely from the upper rack slide tracks. We would also recommend checking parts of the dishwasher pump and motor assembly as if the ball bearings have fallen into it, it may have damaged it. Hope this helps.
Hello Maria, Thank you for the question. We have a 1 Year Warranty on the parts we sell. We hope this helps!

Does this part come with directions?
The arm came off during a cleaning and I snapped back on and the clips broke off
For model number MDB8959SFZ4
Hi Lynn, thank you for reaching out. No, this part does not come with the installation instructions. The spray arm is mounted on the water supply. You will get four tabs there that are the locking tabs and four pins on the base. You need to place it in with these pins in between the locking tabs. Put it down and turn the base clockwise till it clicks. We hope this information helps!
