REMOVAL
1. Remove wheel and tire using power tool.
2. Remove engine under cover using power tool.
3. Without disassembling the hydraulic lines, remove caliper torque member bolts using power tool. Then reposition brake caliper aside with wire. Refer to BR-31, "Removal and Installation of Brake Caliper and
Rotor".
NOTE:
Do not press brake pedal while brake caliper is removed.
4. Put alignment mark on disc rotor and wheel hub and bearing assembly, then remove disc rotor.
5. Remove wheel sensor. Refer to BRC-114, "Removal and Installation"
.
 Inspect the wheel sensor O-ring, replac e the wheel sensor assembly if damaged.
 Clean the wheel sensor hole and mounting surface with a suitable brake cleaner and clean lint-free shop rag. Be careful that dirt and debr is do not enter the axle bearing area.
 Apply a coat of suitable grease to t he wheel sensor O-ring and mounting hole.
CAUTION:
Do not pull on th e wheel sensor harness.
6. On 4WD models, remove drive shaft from steering knuckle. Refer to FAX-9, "Removal and Installation"
.

6. Separate upper link ball joint stud from steering knuckle using Tool.
 Support lower link with jack.
7. Remove cotter pin, then remove drive shaft nut.
8. Remove drive shaft bolts from front final drive.
9. Remove drive shaft from wheel hub and bearing assembly. CAUTION:
 When removing drive shaft, do not apply an excessiveangle to drive shaft joint. Also be careful not to exces-
sively extend slide joint.
INSPECTION AFTER REMOVAL
 Move joint up, down, left, right, and in axial directi on. Check for any rough movement or significant loose-
ness.
 Check boot for cracks or other damage, and for grease leakage.
 If damaged, disassemble drive shaft to verify damage, and repair or replace as necessary.

Introduction of Periodic MaintenanceINFOID:0000000003776980
Two different maintenance schedules are provided, and should be used, depending upon the conditions in
which the vehicle is mainly operated. After 60,000 miles (96,000 km) or 48 months, continue the periodic
maintenance at the same mileage or ti me intervals, whichever comes first.
Maintenance for Off-road Driving (4WD only)INFOID:0000000003776981
After driving the vehicle off-road through sand, mud, or water; more frequent maintenance may be required for
the following items:
Brake pads and rotors
Brake lines and hoses
Rear final drive oil, transmission fluid, and transfer fluid
Steering linkage
Drive shafts
Engine air cleaner filter
In-cabin microfilters

Schedule 1Follow Periodic Maintenance Schedule 1 if your driving habits frequently includes
one or more of the following driving conditions:
• Repeated short trips of less than 5 miles (8 km).
• Repeated short trips of less than 10 miles (16 km) with outside temperatures re-
maining below freezing.
• Operating in hot weather in stop-and-go “rush hour” traffic.
• Extensive idling and/or low speed driving for long distances, such as police, taxi
or door-to-door delivery use.
• Driving in dusty conditions.
• Driving on rough, muddy, or salt spread roads.
• Towing a trailer or using a car-top carrier. Emission Control Sys-

PERIODIC MAINTENANCE
(1) If towing a trailer, or using a car-top carrier, or driving on rough or muddy roads, change (not just inspect) oil at every 30,000 miles
(48,000 km) or 24 months. Using automatic transmission fluid other than Genui ne NISSAN Matic S ATF or Matic J ATF will cause
deterioration in driveability and automatic transmission durability, and may damage the automatic transmission, which is not
covered by the INFINITI new vehicle limited warranty.
(2) Refer to “Tire rotation” unde r the “General maintenance” heading earlier in this section.

Checking Brake Fluid Level and Leaks
INFOID:0000000003777006
• Check the brake fluid level in the reservoir tank. It should be between the “MAX” and “MIN” lines on the reservoir tank.
• If the fluid level is extremely low, check the brake system.
• If the brake warning lamp comes on when the fluid is at the correct level, check the brake fluid level switch and the parking brake
switch.
• Visually check around reservoir tank for fluid leaks.
Checking Brake Line and CablesINFOID:0000000003777007
1. Check the brake lines and hoses for cracks, deterioration, and other damage. Replace any damaged parts.
CAUTION:
If brake fluid leaks are visible around the brake line joints,
retighten the joint, or replace damaged parts as necessary.
2. Check for brake fluid leaks by fully depressing brake pedal while engine is running.
Checking Disc BrakeINFOID:0000000003777008
ROTOR
Check the rotor condition for wear or damage. Refer to BR-7, "DISC
ROTOR : Inspection" , BR-9, "DISC ROTOR : Inspection" .
CALIPER
Check the caliper for any l eaks, repair as necessary.
