Cam Phaser Set for Ford Expedition (2005-2014) 4.6L 5.4L

Direct-Fit VVT Cam Phaser Sprocket Set for 2005-2014 Ford Expedition (U222 / U324)

What it Does: The Cam Phaser Set replaces worn variable valve timing sprockets on the 2005-2014 Ford Expedition to restore accurate camshaft timing, eliminate valve train knock, and clear VCT-related check engine lights.

The Stock Ford Expedition Cam Phaser Failure

Factory variable camshaft timing actuators on the Modular 3V and Triton 3V engines suffer from persistent internal vane wear and locking pin degradation. Under low hot-idle oil pressure, the factory phaser rotor oscillates violently against the stator housing. This continuous hydraulic cavitation shears or distorts the locking pin seat, preventing the camshaft from mechanically locking at base idle. The result is the notorious "diesel chatter" valvetrain noise, rough idle, poor low-end cylinder filling, and recurring diagnostic trouble codes such as P0011, P0012, P0021, and P0022.

The Engineering Solution

This replacement cam phaser pair is engineered with hardened alloy steel internal rotors, precision-ground locking pins, and fatigue-resistant coil springs. Machined to tight internal tolerances, the fluid chambers reduce internal bypass leakage to ensure prompt advance and retard response even during lower operating oil pressures. Each unit restores stable camshaft indexing, resolving erratic ignition timing and dynamic compression loss. Supplied with new torque-to-yield mounting bolts to replace OEM part 3R2Z-6A257-DA and 917-250, this kit secures camshaft clamping load and eliminates harmonic slippage.

Frequently Asked Questions & Fitment Warnings

Does this fit the U222 / U324 Expedition?

Yes, this is a direct fit for the 2005-2014 Ford Expedition equipped with the 4.6L or 5.4L Modular 3-Valve engine. This kit will not fit 2-valve (2V) engines.

Are new camshaft phaser bolts required during installation?

Yes, cam phaser bolts are torque-to-yield fasteners that stretch upon torque application and must never be reused; this kit includes both replacement bolts.

The Ford Towing & Utility Standard

Full-size Ford SUVs demand uncompromised low-end torque for sustained towing and heavy payloads. Restoring proper VVT phase control ensures steady cylinder pressures, factory torque curves, and extended valvetrain durability under high thermal loads.
