Fuel and Refueling -> Rear Axle for Your Ford Explorer SUV Sixth Generation (2012-2020)

Rear Axle  
LIMITED SLIP DIFFERENTIAL  
(IF EQUIPPED)  
This axle provides added traction on  
slippery surfaces, particularly when one  
wheel is on a poor traction surface. Under  
normal conditions, the limited-slip axle  
functions like a standard rear axle. The axle  
may exhibit a slight noise or vibration  
during tight turns with low vehicle speed.  
This is normal behavior and indicates the  
axle is working.
