I am an idiot so please bear with me and help if you have any knowledge with my problem. Our Mechanic left a couple weeks ago. I am a handyman but no mechanic, but for the time being, I'm getting through. I'm dealing with an ASV skid steer SR-70 and twice this summer and now today the front left assembly hub has fallen out of the tracks and I'm not sure what the mechanic have done or isn't doing that could be causing this to be happening. Any thoughts? thank you
