• 5.9L Magnum V8 – Rare, as it was only available on MY1998 Limited models

• Linkage and viscous coupling in V8 models with the full-time 4WD “NP242” transfer case goes bad – this does not affect vehicles with the part-time 4WD “NP231” transfer case
• The transmission may hold gears for too long, too little, or shift erratically. This can be caused by a few things:
  • Automatic transmission fluid level may be low
  • Kickdown cable may need adjustment – if it has stretched out too long (which can happen over time), it may require replacement
  • The transmission may need new fluid and a new filter
  • The Governor Pressure Sensor and Shift Solenoid can go bad; they’re easily accessible by dropping the pan
  • The Throttle Position Sensor (TPS) may be faulty or have incorrect voltage
• Idle issues can be caused by:
  • Clogged/faulty idle air control (IAC) valve
  • Clogged/dirty throttle body
  • Vacuum leaks – these are all old cars now, so the rubber vacuum lines in the engine may be dried out and cracked
  • Failed fuel injector O-rings
• Clunking from the rear end can be caused by:
  • Failing universal joints on the driveshaft
  • Loose caliper bolts
  • Rear driveshaft slip joint may need to be re-greased
  • Worn bushings on the upper and lower control arms
  • Worn shock mounts/bushings
  • Worn transmission mounts
  • Worn exhaust hangars and bushings
  • Stretched transfer case chain
• Clunking from the front end can be caused by:
  • Worn sway bar links/bushings
  • Bad joints in tie rod ends and drag link ends
  • Track bar bushings
  • Worn ball joints
  • Failing universal joints on the driveshaft or axles
• Leaking transmission fluid can be caused by:
  • Cracked/failed lines that run to/from the radiator
  • Failed transmission pan gasket
  • Failed transmission output seal
  • Plastic connectors that snap into the radiator
• Sloppy steering can be caused by:
  • A steering box that needs adjustment
  • Worn/broken ball joints
  • Slop in front end components when turning steering
  • Air in the power steering system – burp it by turning the wheel lock-to-lock several times
• Clicking during sharp turns can be caused by a bad CV axle
• Bogging down or stalling can be caused by:
  • Low fuel pressure (symptom of clogged fuel filter or failing fuel pump)
  • Failed upstream oxygen sensors
  • Clogged/collapsed catalytic converters
• “Death wobble” can be caused by:
  • Failed ball joint ends or bolts on the track bar
  • Damaged/worn tie rod ends
  • Being out of alignment
  • Worn upper and lower control arm bushings, sway bar links, and sway bar bushings
  • Bent/damaged suspension components
  • Play in the ball joints

• Vehicle information center (VIC) randomly throws errors
• Autodim rearview mirror breaks
• Alarm system will randomly drain the battery until it’s dead – and the alarm in general is awful. Chances are, if you can’t start the car, it’s the alarm causing it.
• Factory radios and speakers are “flaky”
• Rear wiper dies – happens because water gets into the arm and corrodes the shaft
• Interior dome lights that won’t turn off can be caused by blown fuses, stuck/unplugged door close buttons, or faulty relays in the fuse panel
• Windshield wipers not returning to their original position can be caused by:
  • Blown fuses
  • Failed intermittent wiper control module (located under the driver-side dash or under the removable grille under the windshield) or intermittent wiper relay (located in the Power Distribution Center)
  • Failed multi-function switch
  • Failing wiper motor
• Power windows not working can be caused by snapped wires in the door jambs or faulty window switches
• Parasitic drain can be caused by blown fuse #7, faulty solder joints on the Body Control Module (BCM), or faulty switch on the rear wiper
• The climate control may only blow at certain speeds or not blow at all; this can be caused by:
  • Failed blower motor resistor
  • Failed blower motor
  • Failed climate control unit
  • Vacuum leak at the firewall “T” next to the A/C lines – often causes air to only blow out of the defrost vents
• Heated seats – failure is often caused by worn wiring on the outside edge of the seat underneath the seat cover
• Flickering headlights or interior dimming issues can be caused by a faulty headlight switch
• ABS faults can be caused by:
  • Failed wheel speed sensor wiring and lines
  • Faulty ABS module
  • Blown fuses
  • Faulty Hydraulic Control Unit
  • ABS relay/box unplugged
  • Failed ABS pump

• Doors go out of alignment or fall off entirely – happens most often with driver-side front door, caused by failing door pins
• Condensation forms on the passenger-side front floorboard – often caused by a clogged A/C drain or failed heater core
• AC Evap system can spring a refrigerant leak
• Foggy headlights
• Tailgate won’t open
• Sagging headliner
• Leaking sunroof seals
• Rust, especially on:
  • Lower parts of doors
  • Rocker panels
  • Bottom of the tailgate
