A limited slip isn't much better then a pegleg open rear. Under load they will spin one tire all day long. Jack up the rear end and get the tires off the ground. Put the transmission in neutral and spin one of the tires by hand. If the opposite tire spins in the same direction, you have a limited slip differential. If the opposite tire spins in the opposite direction, you have an open rear end.Help a newbie out... LSD = "limited slip differential"? Peg leg=??
How do you determine if you have limited slip in your truck? Is there a designation on the diff housing?
