Dtc u 1418
 
Apparrently not in the thread for the DTC's. Jeep set the ABS and TCS lights on, and the only dtc that shows is U 1418.

Just replaced my transfer case day before xmas eve, and the rear driveshaft last week. Also replaced the rear axle fluid and additive.

Jeep has a jack hammer like grinding noise under de-celeration, and loud moaning/whine noise while accelerating that sounds like its coming from the front now.

Could this be the front Drive shaft? Or maybe even front Diff?

Thanks in advance.

2007 WK Manual:

When Monitored:
The Solenoid is active, no solenoid supply circuit DTCs are present and battery voltage is normal.

Set Condition:
The FDCM detects the Front Differential Solenoid Control is high.


Possible Causes

FRONT DIFFERENTIAL SOLENOID

(T306) FRONT DIFFERENTIAL SOLENOID CONTROL CIRCUIT SHORTED TO BATTERY VOLTAGE

(T306) FRONT DIFFERENTIAL SOLENOID CONTROL CIRCUIT SHORTED TO (T301) SWITCHED BATTERY SOLENOID SUPPLY CIRCUIT

FINAL DRIVE CONTROL MODULE (FDCM)

I would replace the solenoid before i replaced the whole diff.

The solenoid is a $20 part, but I bet it's a bitch to get to on the front diff. It was very easy to replace on the rear.
