Mopar 68394210AH is the current front wheel speed sensor for the JL and Gladiator. It supersedes 68394210AC through AG. A failed front sensor is one of the cheaper reasons for ABS and traction lights on a JL, and worth ruling out before blaming the ABS module or wiring.
Fitment
2018-and-later Wrangler JL and Gladiator JT, front left or right, per Mopar dealer listings. Always confirm the number on your old part or run your VIN at a Mopar parts counter before you order.
Common failure symptoms
- ABS and traction control lights on with a front wheel speed code
- Lights that started after a lift install or trail damage
- ABS activating on dry pavement at low speed
- Speed-related warnings alongside network codes like U0121

Rebuild, repair or replace?
Replace, don't repair. Read the codes so you know which wheel. Inspect the harness along the knuckle, especially on lifted JLs where it can stretch at full droop. If the codes are communication faults (U0121) rather than a single wheel sensor, see our JL U0121 guide first. Aux battery bypasses and module connectors are common culprits there.
On JLs, a wheel-speed problem rarely shows up by itself. Owners in our U0121 research saw the ABS, ESP/BAS and traction lights come on together, sometimes with U1110 (lost vehicle speed message) or U1120 (lost wheel distance message) codes. Those network codes point to communication with the ABS module, while a code naming one front wheel points to that sensor or its harness. A-Premium lists its APABS3465 for 2018–2025 Wrangler front positions. Whichever brand you buy, clear the codes after installing and do a test drive above about 20 mph so the module sees the new sensor's signal.
