According to the manufacturer, they include a washer that is supposed to keep the shock from slipping off the sleeve. As you can see, the shock just slipped through the little hole in the end of the shock. So, back to the manufacturer, I spoke to a nice guy named Dieter. He says that this has been a very widespread problem.
They include the washer in the kit but they put it on top of the shock because they don't want it to get lost or to clang around in the box during shipping. They are discovering that most DIYers put the washer on top, where it is shipped, instead of on the bottom where it is designed to prevent exactly what you see in this pic.
I swear there were no instructions to this install, which I look for when I work on my car. So, Dieter and I had a nice chat, he agreed to put in a new bushing and sleeve if I wanted to ship him the part. I don't have time for that. I engineered a long bolt and washer to force the sleeve back into the shock and then remounted it with the biggest washer i could purchase from the local hardware store.
Fixed!!
Thx for your interest/help!!
