The model number that you gave doesn't show up in the Ariens parts lookup system, so I can't tell what it looks like. Normally the Ariens model number is a series of 6 numbers, with most starting with 9. Also any information you can provide as far as how it is used. Like used to tow a lawn cart, or roller. I think you have a situation of how it is used, with unrelated problems, and then topped off with just a faulty spindle.
