I was riding in Moab a couple days ago (first time!) and while riding up a slick rock hill on a trail, I heard a loud bang. When I stopped, there was blue smoke everywhere and oil dripping under the swingarm. Rolling around on top of the swingarm was the shock reservoir and there were aluminum threads stuck all over the place. We found some other internals from inside the reservoir on the trail where it blew up. Is this an expected way for A WP shock to fail? I wasn't riding that hard but the reservoir was definitely very hot. Some history: About a week earlier, I had the shock and forks in the local shop to put on the 'R' suspension kit and the ride in Moab was the first time off road after the work was done. They also replaced the rebound adjuster because it was seized. Would they have had to take the reservoir off to put the new spring on or to replace the adjustor? I'm wondering if they could have botched the job somehow.. maybe damaging the threads causing the reservoir to blow off like that?
