Thanks. I already work on a driveway that is somewhat sloped so I feel like I'm probably already pushing the envelope a bit as is LOL. I've swapped wheels on multiple vehicles over the years, I'm just a bit surprised that yesterday when I went to do it on my Durango it was not at all obvious where I should be putting the jack in front. I guess the jack included with the vehicle is probably built to pick it up by the front flange? I'm only using the onboard car jacks in emergencies. They can be junky.The front is a little jinky for an obvious jack point...so what I do instead to change wheels ect is only use the rear point which is more obvious and robust looking and go high enough to lift front tire off ground...saves time.
