In college I drove a ‘92 Jeep Cherokee. It had a full size spare (can’t remember if it came with one, or I might have picked one up somewhere), but the problem was the little bottle jack the Jeep came with.
I had a flat tire one night (after midnight), pulled over on the side of the highway, jacked it up, got the flat tire off, but didn’t have it high enough to get the spare tire on. Jacked it up more, as far as the little bottle jack would go, still not enough clearance for the fully inflated spare.
So I figured I’d lower it back down and see if I could find a better spot for the jack… except now that it was fully extended, it wouldn’t go back down.
I tried everything I could think of before calling my dad, who had been asleep and lived about 45 minutes away. He came to the rescue with a floor jack, which lived in the back of that Jeep for the rest of the time I owned it.
