Founding Member. The limited slip is like a car/truck limited slip. Which is why Frontier 4x4s offer 4-wheel Limited Slip (ABLS). If all else fails, give the dealer your VIN# and they can tell you. To solve that problem the systems usually include some form of locking or limited slip differential in the rear or both rear and front axles. The differential will still drive at least one wheel, even though the limited slip is knackered. A limited slip differential maintains traction by “sensing” when one wheel is slipping, locking the wheels together and thereby redirecting greater torque to the non-slipping wheel. It was wrong! If it tells you your truck has a G80 limited slip its lying to you. The reason we have a differential in the axle is to allow turns without tire scuffing. These wheel speed sensors monitor the speed of the wheels and determine if one or more have lost traction. Procedure for changing the rear differential fluid in a 100: Draining: Drive the vehicle to warm-up the gear oil.
