If a thumping or creaking noise is heard from the transmission tunnel area while driving over bumpy roads, a transfer case shifter repair kit is available which should correct this concern.
Vehicles with manual temperature control may develop a condition where warm air is coming from the instrument panel outlets when cold has been selected. Our technicians tell us a revised air distribution housing is available to correct this concern.
One the 3.9L V6 and 5.9L V8 the 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 the 3.9L V6 and 5.2L V8 it is often misdiagnosed as a leaking oil filter gasket, the oil filter adapter can seep from between the adapter and engine block.
If the alarm sounds without anybody disturbing the vehicle (usually in the middle of the night), a new hood striker plate is available. Made of thicker material, it will maintain contact with the hood switch as the vehicle's sheet metal cools.
