Product review (5 stars): Excellent replacement part!!!!
These axles are fantastic!  I used them to replace the melted, broken and no longer functional axles for my GE Profile dishwasher (PDW9000 - part number for the wheel pack is WD35X21041).  These fit beautifully, and I didn't need the wheels, just the axles.  The old ones were useless.  They had broken off, folded under the rack, melted, cracked, flaked and were otherwise completely worthless.  The design of the originals was horrible, as was the detergent dispenser that was part of the original design of the dishwasher.  I didn't use that for more than a couple of weeks before I was so grossed out by the thing that I stopped using it.  There was no way to flush or clean it.  It clogged very easily, with no way of unclogging it.  It was disgusting.  The thing still disturbs me.  Even though I haven't used it in at least 5 years.

Anyhow, the axles are great.  They take a bit of elbow grease to remove from the wheels.  I used a flathead screwdriver to compress the middle spring to release the post and take out the axle.  I then replaced the new ones and pushed them into the wheel until they clicked, and then pushed them into place on the rack, until they popped.  I now have a rack that is functional again, that rolls easily, and that I can use without using naughty language.
