While alone (bad idea) on John Bull Trail - Big Bear Lake area, before Teebes arrived, I slid sideways due to unfamiliarity with my new (used) tires. Sigh. The rock was like the Matterhorn, all sharp and pointy, and one peak got me in the driveshaft. While I was still trying to drive off it. Bad idea #2.
I have a junkyard one enroute for $62 shipped, but here's the advice to all of you. I forget when the changeover was, but I am so totally glad I had the steel version, not the aluminum. Aluminum would probably have crumpled or creased.
Please check in with your model and year if you have the aluminum, and consider a swap for strength.
