There are two "spindles" sets on your mower. One set holding the front wheels to the mower. The other set Holds the blades to the cutter housing.
The front axle spindles cost about $40 each and take less than an hour to replace them yourself.
The spindles holding the blades cost anywhere from $30 to $70 each. The $30 spindles are as good or better than original equipment. I spent about 4 hours removing a 42" deck, power washing the whole thing, replacing the spindles, sharpening the blades, reinstalling, washing the machine, greasing all the zerts, mowing my front yard as a test drive.
