C0050 on Jeep by model: symptoms, diagnosis and fix
Front (and sometimes rear) sealed wheel hub/bearing assemblies are a high-wear item on JK and JL Wranglers, especially on lifted rigs running larger tires that load the bearing harder. As the bearing wears it produces a speed-dependent grinding, rumbling, or humming that changes when turning, and free play can be felt by rocking the tire at the 12-and-6 positions. Because the ABS wheel-speed sensor (tone ring/sensor) is integrated into the hub assembly on these models, a failing hub commonly damages the sensor and triggers ABS and traction-control (ESC) warning lights along with disabled stability control. The common service hub assembly for 2007-2016 5-lug JK with ABS is part 513272 (Mopar/MOOG/Timken/Spicer equivalents); note a JK hub part-number change around 2011, so the correct year-specific part must be used.
Common Symptoms
- Grinding/humming that rises with speed
- Noise changes when turning
- Play when rocking tire top/bottom
- ABS warning light
- Traction control / ESC light
- Vibration in steering wheel
How to Fix
Confirm the bad corner by road-test noise direction and the 12/6 rock test for play. Replace the complete hub/bearing assembly (the integrated ABS sensor is part of the unit). For 2007-2016 5-lug JK with ABS the common service part is assembly 513272 (Mopar/MOOG/Timken/Spicer equivalents); verify the correct part for your year due to the ~2011 design change. Inspect/clean the ABS connector and clear codes; the ABS/ESC lights should extinguish once the hub and its sensor are replaced.

Frequently asked questions
What does C0050 mean on a Jeep?
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 Jeep it is documented across 1 model: Wrangler.
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 Jeep?
Published repair estimates on Jeep range from $150 to $600 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
