I am trying to fix tyhe steering on my daughters Ariens 19HP 42 Inch cut mower. I need to replace the right front wheel spindle. This mower was manufactured by Husqvarna Outdoor Products formerly AYP. The Ariens part number is 21546583 and the Husqvarna/Craftsman part number is 532403088. Are these parts interchangeable. When I look at steering parts drawings for either brand they look identical, same diagram number, different part number. The Husqvarna/Craftsman part is half the costs of the Ariens part. Anyone know if the will interchange? Any help appreciated
