Headliner Sagging:
Common issue with aging adhesive on the headliner fabric.
Nikasil Liners:
Early 4.0L V8 engines (AJ26) used Nikasil cylinder liners, which could be susceptible to corrosion from high-sulfur fuels. Later models (AJ27 onwards) used Alusil.
Plastic Coolant Fittings:
Plastic fittings in the cooling system can become brittle and leak over time. Often replaced with metal upgrades.
Heater Control Valve:
Failure of the heater control valve can lead to erratic temperature control.
ABS Module:
ABS warning lights and faults can sometimes indicate issues with the ABS control module or sensors.
