Well that didn’t take very long! Thirty minutes into our journey we heard a weird noise from the front of our Cherokee, which turned out to be the hydraulic bumpstop that had managed to slip out of the can. A few hard sideways bounces let the coil catch on the bumpstop a few times and pulled it out enough to damage and bend the can. A quick decision was made to just pull it instead of trying to fix it. At least we all got a quick lesson on how to properly operate a Hi-Lift jack.
