ENGINE ASSEMBLY
2007 Versa
INSTALLATION
Note the following, and install in the reverse order of removal.
Do not allow engine oil to get on engine mounting insulator. Be careful not to damage engine mounting
insulator.
When installation directions are specified, install parts according to the directions. Refer to EM-73, "Com-
ponents" .
Make sure that each mounting insulator is seated properly, and tighten nuts and bolts.
Tighten engine mounting insulator (RH) bolts in the numerical
order shown.
INSPECTION AFTER INSTALLATION
Inspection for Leaks
The following are procedures for checking fluids leak, lubricates leak and exhaust gases leak.
Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to MA-11, "
RECOMMENDED FLUIDS AND LUBRICANTS" .
Use procedure below to check for fuel leakage.
–Turn ignition switch “ON” (with engine stopped). With fuel pressure applied to fuel piping, check for fuel
leakage at connection points.
–Start engine. With engine speed increased, check again for fuel leakage at connection points.
Run engine to check for unusual noise and vibration.
Warm up engine thoroughly to make sure there is no leakage of fuel, exhaust gases, or any oil/fluids
including engine oil and engine coolant.
Bleed air from lines and hoses of applicable lines, such as in cooling system.
After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the
specified level, if necessary.
Summary of the inspection items:
* Transmission/transaxle/CVT fluid, power steering fluid, brake fluid, etc.: Vehicle front

On-Vehicle Inspection and ServiceEDS003TJ
Check the axle and suspension parts for excessive play, wear, or damage.
Shake each front wheel to check for excessive play as shown.
FRONT WHEEL BEARING INSPECTION
Move wheel hub and bearing assembly in the axial direction by hand. Make sure the axial end play is
within specification.
Check that the wheel hub bearing operates smoothly.
Replace the wheel hub assembly if the axial end play exceeds specification, or if the wheel bearing does
not turn smoothly. Refer to RAX-4, "
Removal and Installation" .
CAUTION:
The wheel hub assembly does not require maintenance. If any of the following symptoms are
noted, replace the wheel hub assembly.
Growling noise is emitted from the wheel hub bearing during operation.
Wheel hub bearing drags or turns roughly.

2. Without disassembling the hydraulic lines, remove the torque member bolts using power tool. Then repo-
sition the torque member and brake caliper assembly aside with wire. Refer to BR-24, "
FRONT DISC
BRAKE" .
CAUTION:
Do not depress brake pedal while brake caliper is removed.
3. Put alignment marks on disc rotor and wheel hub and bearing
assembly, then remove disc rotor.
4. Remove wheel sensor from steering knuckle. Refer to BRC-33, "
WHEEL SENSORS" .
CAUTION:
Do not pull on wheel sensor harness.
5. Loosen steering outer socket (1) nut.
6. Remove steering outer socket (1) from steering knuckle (2) so
as not to damage ball joint (3) boot using ball joint remover or
suitable tool.
CAUTION:
Temporarily leave the outer socket nut installed to prevent
damage to threads and to prevent the ball joint remover or
suitable tool from suddenly coming off.
7. Remove transverse link ball joint nut and bolt. Then, remove transverse link from steering knuckle.
8. Remove cotter pin, then loosen hub lock nut using power tool.
CAUTION:
Temporarily leave the hub lock nut installed to prevent damage to threads.
9. Separate the drive shaft from the wheel hub and bearing assem-
bly by lightly tapping the end of the drive shaft using a hammer
or suitable tool, and then remove hub lock nut.
NOTE:
Use a suitable puller if wheel hub and bearing assembly and
drive shaft cannot be separated after performing the above pro-
cedure.
10. Remove the drive shaft from the wheel hub and bearing assem-
bly and support the drive shaft.
CAUTION:
Do not apply an excessive angle to drive shaft joint when
removing from the wheel hub and bearing assembly,
Do not excessively extend slide joint.
