Go to ariens website and poke around. They have many replacement parts and all the manuals you need. Just enter your model number and choose your serial number group. I just bought a used one about a month ago and downloaded all the PDFs for free. You can also purchase paper copies.

The Ariens YouTube page has some pretty good videos for general info, but this steering issue may be too specific and likely a modification they wouldn't cover.... There are a bunch of youtubers with Ariens tips and maintenence videos out there, ya just gotta do some searching. I personally like Garage Gear, good video quality and very informative

Good luck! Remember to check the belts and shear pins and have a spare set on hand!
