I bought an A last summer, with a belly mower, for our yard. So far, it's been great, but has had pretty loose steering. Two weeks ago, it just locked up. Barely turn one way or the other. I unscrewed the cap on the front of the steering box and 3/8" bearings started falling out... I've got most of it apart, but I'm kinda stuck now. I'm no mechanic, but can usually figure things out. When I push the steering rod all the way back toward the seat, it turns that tie rod connector back and forth perfectly. I can't seem to find an exploded picture of what goes into that steering box. Do I need to completely remove the front axle to get that box off and get inside to check everything out? I NEED HELP!
