Just picked up this 1998 4 x 4 extended cab with a 3.0 L. My first Ford Ranger, I’ve been catching up on 20 years worth of maintenance but she runs pretty good for being 20 something. 156k miles. Currently the list of work done over the last week or so: new rear end front differential fluid, transfer case fluid, new belt, new DPFE Sensor and silicone hoses, cleaned idle air control valve and mass airflow sensor, Heat treatment in the gas tank, checked and cleaned rear drum brakes, pcv valve, fuel filter, air filter, put a camper shell on her. Have a new cam sycro in hand I’m going to replace as a precaution. Only real issue that’s popped up is a horrible squealing I’m trying to find. Water on the belt quiets her down so hopefully the new idler pulley does the trick if not I think a new tensioner is in order. Thanks for having me on the forum
