A few years ago I was fishing a small lake that was only accessible with tracks or a snowmobile. It was 2 miles to where I was fishing, Probably 1.5 miles on a snowed in road and .5 mile on the ice. Anyway on one of my trips there, on the way in I had a track fall off my ranger. Basically the hub broke as the metal is to thin, causing the complete track system to fall off, fortunately it broke the anti sway bar also, which allowed me to throw the track in the box with my fishing gear and then I drove out on three tracks and the sprocket where the track broke off. It was a little sketchy going over big drifts as the sprocket side would fall in and you felt like you were going to tip over. The other tracks did a good job of dragging me through all that snow and I got back to my trailer and got it loaded. I did have a wtf am I going to do moment when it first happened. Here I am 1+ miles down a snow covered drifted in road that there was no hope of driving down with a pickup, poor to no cell coverage. It happened to me again about 3 years later with the rear track on the other side but at a different lake. This lake I was fortunate because I was able to drive my pickup and trailer to it and load my broke down ranger on. This time the anti sway bar didn't break and i didn't have the metric wrenches with to take if off so I just drove on the trailer dragging the track along with. Now I look at the insides of each hub and check for cracks when I install them.
