C0055 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 C0055 mean on a Jeep?
C0055 stands for "Rear Wheel Speed Sensor Circuit." This chassis code means the ABS/control module detected a problem with the rear wheel-speed sensor signal circuit. Wheel-speed sensors tell the module how fast each wheel is turning so it can manage anti-lock braking, traction, and stability control; on many GM trucks and SUVs this code points to a single rear/output speed sensor at the transmission or transfer case. A lost or erratic signal typically disables ABS and traction control (warning lights on), affecting braking safety, so it should be addressed promptly. On Jeep it is documented across 1 model: Wrangler.
What are the most common causes of C0055?
The most common causes of C0055 are: Faulty rear/vehicle speed sensor, Damaged, corroded, or open sensor wiring and connector, Debris or damage on the reluctor/tone ring, Excessive air gap or sensor mounting issue, Poor ground or shorted circuit, Faulty ABS/EBCM module (less common). The specific cause varies by vehicle.
How much does it cost to fix C0055 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.
