Engine

5.4L Triton V8

• Spark Plug Breakage
  • Description/Symptoms: The 5.4L Triton V8 engine is known for spark plugs that can break upon removal. This is due to a two-piece spark plug design used in certain years of this engine. This can lead to significant difficulty in spark plug replacement.
  • Solution: Specialized tools are available to remove broken spark plugs. A professional mechanic may be necessary. It’s also crucial to use the correct torque specifications when installing new plugs to avoid future issues.
  • Estimated Cost to Fix: $200 - $1000+ (depending on the number of broken plugs and labor costs)
  • Recalls: None Found
• Cam Phaser Issues
  • Description/Symptoms: Ticking or rattling noise, especially on startup. Rough idling and potential loss of power. Error codes related to cam timing. This is due to wear or failure of the cam phasers, which control valve timing.
  • Solution: Replacement of the cam phasers, timing chain, and potentially other related components like the VCT solenoids. This is a fairly involved repair.
  • Estimated Cost to Fix: $1500 - $3000+
  • Recalls: None Found

Transmission

6-Speed Automatic (6R80)

• Harsh Shifting/Slipping
  • Description/Symptoms: Abrupt or jerky shifts between gears, especially under acceleration. Slipping feeling during gear changes, where the engine revs up without a corresponding increase in speed. Can also include delayed engagement into drive or reverse. This can be caused by worn valve body components, internal clutch wear, or low transmission fluid.
  • Solution: A transmission fluid flush and filter change may resolve minor issues. More severe cases may require valve body replacement or a complete transmission rebuild or replacement.
  • Estimated Cost to Fix: $150 (fluid flush) - $4000+ (rebuild/replacement)
  • Recalls: None Found

Suspension

• Rear Leaf Spring Sagging/Broken Leaves
  • Description/Symptoms: Rear of the truck sitting lower than normal. Reduced load-carrying capacity. Clunking noises from the rear suspension, especially when going over bumps. Visible cracks or breaks in the leaf springs.
  • Solution: Replacement of the rear leaf springs. Consider upgrading to heavier-duty springs if the truck is frequently used for towing or hauling.
  • Estimated Cost to Fix: $500 - $1500+
