C0050 on Lincoln: How to Diagnose & Fix
Right Rear Wheel Speed Sensor Circuit

C0050 on Lincoln by model: symptoms, diagnosis and fix
A speed-related hum, growl, grind, vibration, or wheel-end play can be consistent with a wheel bearing, but tire tread, wheel damage, brakes, axle or CV joints, driveline components, and other rotating parts can sound similar. The reviewed evidence does not establish a Lincoln Aviator-wide premature front-hub defect or a reliable failure mileage. A bearing diagnosis must identify the corner and drivetrain configuration before any hub is selected.
Common Symptoms
- Speed-related hum, growl, or grind from a front corner
- Noise changes with steering load
- Wheel-end play or roughness confirmed during inspection
How to Fix
Road-test while documenting speed, steering load, road surface, braking, and acceleration effects. Inspect tires and wheels, brakes, axle/CV joints, and wheel-end play; use chassis ears or other NVH tools when needed to isolate the corner. Confirm the exact VIN, RWD/AWD configuration, axle position, side, sensor configuration, and current Ford supersession in the parts catalog before ordering a hub. Do not infer C0050 or C0040 without a scan. This record intentionally has no commerce link until diagnosis and VIN-specific fitment are known.
Owner tips & cautions
- TipAsk the technician to document the isolated corner and the NVH evidence, then verify RWD/AWD and current VIN-specific hub supersession before ordering.
- WarningNoise that changes in a weave can suggest a wheel end but is not conclusive; tires, brakes, and driveline sources must be excluded.

Frequently asked questions
What does C0050 mean on a Lincoln?
C0050 stands for "Right Rear Wheel Speed Sensor Circuit." This is a brake/ABS-system code. The right rear wheel speed sensor reports how fast that wheel spins so the anti-lock brake, traction control, and stability systems can do their job. C0050 means the ABS module detected an electrical fault in the right rear wheel speed sensor circuit — an open, short, or an erratic/out-of-range signal. This usually turns on the ABS and traction/stability warning lights and may disable those features, though standard braking remains available. On Lincoln it is documented across 1 model: Aviator.
What are the most common causes of C0050?
The most common causes of C0050 are: Failed right rear wheel speed sensor, Damaged, corroded or disconnected sensor wiring/connector, Damaged or rusty tone/reluctor ring (missing or clogged teeth), Excessive air gap between sensor and tone ring, Wheel bearing wear affecting an integrated sensor, Moisture or corrosion in the connector, Faulty ABS control module (less common). The specific cause varies by vehicle.
How much does it cost to fix C0050 on a Lincoln?
Repair costs vary widely with the root cause and Lincoln model; each issue on this page carries its own estimate where one is published.
