It all depends on what year the truck is and what type of air dryer it has on it now? The old type the filter just unbolts and is replaced, the newer type the filters unscrew and have diff. types of medal on the housing and filter and can be like getting a bears jaw apart, and have air lines that control ride hi. of truck and air ride cab and up to 4 other things, and its best to try too get filter off 1st then replace it with a name brand filter, If you can't take it off, pull the hole thing off the truck leaving all hardware in place on frame of truck, and bring the ck. book with you to parts store and be sure to buy a new one not a rebuilt unit air dryer ###.
