Hi guys I have a problem with my 4wd 96 ranger. It seems anytime I start backing up while turning to the left my front end pops. So today I decided to climb under it to inspect and I found that the "axle shaft" (not sure if that's the right terminology) has popped out about a 1/2 an inch. It's on the passenger side. I was wondering what the problem might be, and what i could do to fix it.
