What is making this happen? on 1999 Cadillac Escalade

The rear axle seems to be binded up when I pull out or back out of say a parking spot. I went to the store the other day and I started to pull into the parking spot and my car just stopped. I had to give it gas to make it roll into the spot. My axle acted like it was in a. Ind or like something was sticking. What might this be?
