A ticking type noise may develop, most noticeable when the engine is cold. This is commonly caused by one or more broken exhaust manifold bolts. Our technicians recommend to replace the broken bolts as needed, also the exhaust manifold gaskets should be replaced at this time.

Most reported 2001 Dodge Durango problems
Front and rear differential pinion seal leaks are common. A leaking pinion seal will require replacement.
On the 4.7L V8 engine, the Camshaft position sensor failure can cause the engine to crank but not start or it can cause intermittent stalling. A new camshaft position sensor will be needed.
If the door locks intermittently lock and unlock without pressing the door lock switch, the door and liftgate lock cylinder switches may need replacement. This may occur more often when driving in damp conditions like the rain or through a car wash.
If the transmission delays initial gear engagement after being parked overnight or longer, it may be due to a suspect transmission cooler return filter. If the transmission was recently serviced and the part number for the cooler return filter contains an "AB" suffix at the end, a new filter should be installed.
External oil leaks from the valve cover gaskets, intake manifold gaskets (front or rear), and the rear crankshaft seal area are common. The rear main seal is an unlikely source. Normally, leaks in this area are from the bearing cap mating surfaces as well as the sealing surface between the oil pan and bearing cap.
On the 5.9L V8 engine, rerouting the ignition coil wire and spark plug wires can help solve a misfire and/or surge problem that occurs at approximately 45 mph. A service bulletin was published that outlines the specifics of the repair. It states the rerouting procedure should be performed before other repairs are done for misfires, surging or spark knock.
One the 5.9L V8 carbon buildup on the top of the piston is common. As the buildup increases with mileage and over time, symptoms may vary from light ticking, to ticking/hammering, to hammering/knocking noises. Fuel injector cleaner often solves the problem.
On 3.9L V6 and 5.9L V8 engines, the intake manifold gasket may leak and cause increased oil consumption and a spark knock during acceleration; the gasket should be replaced.
