Have a 2003 toyota tundra v6 manual sr5. Recently purchased. Trying to replace the front differential. The vacuum tubes and breather hoses have been previously cut. I cannot figure out where they should go to. I have the FSM. Cannot locate breather hose anywhere besides on the breakout diagram of front differential. Located vacuum hose running into front of engine but image does not match truck I have. Then I read somewhere that possible the hose for the add is not actually vacuum but just an additional breather? Where should these hoses run to? Looked all over the internet for info, cannot find anything that matches what I have. There is no vacuum cylinder in a wheel well as suggested all over the place. Any insight would be greatly appreciated.
