Product review (5 stars): Solid replacement part and DIY job was easy.
I replaced all four on my LG DLG2524W. These are solid, and you do not need to pay another 10 bucks for the axles, but read further. I used the old ones, and plastic clips. However, one of the axles did have a burr in it, so I had to take a dremel to clean up the thread to reuse it. With that said, if you are worried I would buy three of these and one with an axle at best. It appears the two rollers on the front wears faster than the rear ones. I didn't need to change the rear ones after 6 years, but did it anyways b/c I bought the parts before taking my dryer apart.
