I got the "opportunity" to try my jack New Years Eve . About two months ago I actually looked at my Transit to see where the jack, lug wrench, etc. were all located in case I ever needed to use them one day. It all worked well. From pulling over to pulling away with the spare was probably about 25 minutes. It was the front right tire. The jack worked well enough, but with the extension provided it limited the overall stroke. I used just one of the extension pieces and was able to get a full stroke of travel under the van.
