Frelander 2. Manual — part 76
Bearing Rumble
Bearing rumble sounds like marbles being tumbled. This condition is usually caused by a worn/damaged wheel bearing.
The lower pitch is because the wheel bearing turns at only about one-third of the driveshaft speed. Wheel bearing noise
also may be high-pitched, similar to gear noise, but will be evident in all four driving modes.

DTC Index
• NOTE: If the control module or a component is suspect and the vehicle remains under manufacturer warranty, refer to the
Warranty Policy and Procedures manual (section B1.2), or determine if any prior approval programme is in operation, prior
to the installation of a new module/component.
• NOTE: Generic scan tools may not read the codes listed, or may read only five digit codes. Match the five digits from the
scan tool to the first five digits of the seven digit code listed to identify the fault (the last two digits give additional
information read by the manufacturer approved diagnostic system).
• NOTE: When performing voltage or resistance tests, always use a digital multimeter (DMM) accurate to three decimal
places, and with an up-to-date calibration certificate. W hen testing resistance always take the resistance of the DMM
leads into account.
• NOTE: Check and rectify basic faults before beginning diagnostic routines involving pinpoint tests.
• NOTE: Inspect connectors for signs of water ingress, and pins for damage and/or corrosion.
• NOTE: If DTCs are recorded and, after performing the pinpoint tests, a fault is not present, an intermittent concern may
be the cause. Always check for loose connections and corroded terminals.
For a complete list of all Diagnostic Trouble Codes (DTCs) that could be logged on this vehicle, please refer to Section
100-00.REFER to:

CONDITIONS
DETAILS/RESULTS/ACTIONS
A1: CHECK NOISE FROM VEHICLE ON ROAD TEST
Road test vehicle to determine load and speed conditions when noise occurs.
Assess the noise with different gears selected.
Does the noise occur in different gears at the same vehicle speed?
Yes
INSTALL a new rear drive axle/differential assembly.
REFER to:
Differential Case
(205-02 Rear Drive Axle/Differential, Removal and Installation).
RE-TEST the system for normal operation.
No
