Special note: Before installation begins, it is the 
customers/installers responsibility to make sure that 
all parts are on hand. If any parts are missing, please 
feel free to call one of our customer service 
representatives @ (801) 280-2777. 
 
Special post installation procedure: Tuff Country EZ-
Ride Suspension highly recommends adding a 
minimum of 1 pint, but no more that 1 1/2 pints, of 
proper front differential fluid into the front 
differential. To achieve this, you may have to fill the 
differential with it on its side or you may have to 
insert the fluid through the vend tube opening. On 
occasion, the customer may find burping of fluid 
coming out of the front vent tube.
