Forgive me if this is a stupid question but what's the best way to jack up the front end of an XJ? I've used the differential as a lift point in the rear but the front diff is off-center so that won't work. I'm used to being able to find a spot on the frame to use but I didn't see anything that I thought would be safe. The owners manual isn't exactly clear on this subject either so I'd figure I'd ask you guys.
