1. Check for holes and exhaust gas leaks due to damage,
corrosion, etc.
2. Check the joints and connections for looseness and exhaust
gas leaks.
3. Check the rubber hangers and brackets for damage.
9. ENGINE OIL (CHANGE)M1001002600360
Use the specified oil. (Refer to P.00-35.)
Use care as oil could be hot.
1. After warming up the engine, remove the oil filler cap.
2. Remove the drain plug to allow the engine oil to drain.
3. Install a new drain plug gasket so that it faces in the
direction shown in the illustration, and then tighten the drain
plug to the specified torque.
Tightening torque: 39
5 Nm (29 3 ft-lb)
4. Pour new engine oil in through the oil filler hole.
Specified Engine Oil:
To ta l q u a n t i t y :
<3.8L Engine> 4.6 Litres
5. Install the engine oil filler cap.
6. Start the engine and run it at idle for a few minutes.
7. Pull out the oil dipstick slowly and check that the oil level is
within the marks on the oil dipstick.
8. Check that the oil is not excessively dirty, that there is no
coolant or petrol mixed in, and that it has sufficient viscosity.
10. ENGINE OIL FILTER (REPLACE)M1001002700345
The quality of replacement filters varies considerably. Only high
quality filters should be used to assure most efficient service.
Genuine oil filters require that the filter is capable of withstand-
ing a pressure of 1,800 kPa (261 psi) are high quality filters.

GENERAL DESCRIPTION
FRONT AXLE26-2
GENERAL DESCRIPTIONM1261000100370
The front axle consists of front hubs, knuckles, wheel
bearings and drive shafts, and has the following fea-
tures:
The wheel bearing incorporates double-row
angular contact ball bearing for reduced friction.
The front wheel hub assembly combines the hub,
wheel bearing, and oil seal in a single unit for
fewer parts, better durability, improved assembly
precision, and better structural organization.
The driveshaft incorporates BJ-PTJ type constant
velocity joints with high transmission efficiency for
low vibration and noise.
Due to the use of the inner shaft and bracket
assembly, the right and left drive shafts are
approximately the same in length. This reduces
noise, vibration and torque steer.L-RH>
The dynamic damper is mounted on the LH drive-
shaft.
ABS rotor for detecting the wheel speed is
press-fitted to the BJ.

1. Gather information from the customer.

DRIVE SHAFT ASSEMBLY

4. Measure the wheel bearing rotation starting torque by using
the special tools MB990326 and MB990685.
Limit: 1.4 N
m (12 in-lb)
5. If the rotation starting torque is not within the limit when the
nut is tightened to 226
29 Nm (167 21 ft-lb), replace the
front wheel bearing assembly. If there is any signs of binding
or tight spots when the wheel bearing turns, replace it.
6. Measure to determine whether the wheel bearing axial play
is within the specified limit or not.
Limit: 0.05 mm (0.002 inch)
7. If the play exceeds the limit when the nut is tightened to 226
29 Nm (167 21 ft-lb), replace the front wheel hub
assembly.

REMOVAL AND INSTALLATIONM1261003500429
For vehicles with ABS, do not strike the ABS rotors installed to the BJ outer race of drive shaft
against other parts when removing or installing the drive shaft. Otherwise the ABS rotors will be
damaged.
For vehicles with ABS, be careful not to strike the pole piece at the tip of the front wheel speed
sensor with tools during servicing work.
