EXAMPLES OF ABNORMAL
WAV E F O R M S
Example 1
•Wave characteristics
Spark line is high and short.
•Cause of problem
Spark plug gap is too large.
Example 2
•Wave characteristics
Spark line is low and long, and is sloping.
Also, the second half of the spark line is distorted.
This could be a result of misfiring.
•Cause of problem
Spark plug gap is too small.Example 3
•Wave characteristics
Spark line is low and long, and is sloping.
However, there is almost no spark line
distortion.
•Cause of problem
Spark plug gap is fouled.
Example 4
•Wave characteristics
Spark line is high and short.
Difficult to distinguish between this and abnormal
waveform example 1.
•Cause of problem
Spark plug cable is nearly falling off (Causing a
dual ignition).
Example 5
•Wave characteristics
No waves in wave damping section.
•Cause of problem
Layer short in ignition coil.

GENERAL INFORMATION
FRONT AXLE26-2
GENERAL INFORMATION
M1261000100347
The front axle consists of front hubs, knuckles, wheel
bearings and driveshafts, and has the following
features:
•The wheel bearing is a double-row angular
contact ball bearing which incorporates the oil
seals and is highly resistant to thrust loads.
•The driveshaft incorporates BJ-TJ type constant
velocity joints with high transmission efficiency for
low vibration and noise.•The dynamic damper has been mounted on the
driveshaft to reduce differential gear noise.
•ABS rotor for detecting the wheel speed is
press-fitted to the BJ.
NOTE: .
•TJ: Tripod Joint
•BJ: Birfield Joint

FRONT AXLE HUB ASSEMBLY
FRONT AXLE26-12
DISASSEMBLY SERVICE POINTS
<<A>> HUB REMOVAL
CAUTION
When the hub has been removed, always replace
the wheel bearing with a new part because wheel
bearing frictional surface will be damaged when
removing the hub.
Use the following special tools to pull out the hub
from the knuckle.
•Knuckle arm bridge (MB991056 or MB991355)
•Front hub remover and Installer (MB991017)
•Spacer (MB991000)
<<B>> WHEEL BEARING REMOVAL
1. Crush the oil seal in two places so that the tabs of
the special tool will be caught on the wheel
bearing inner race (outside).
CAUTION
When removing the inner race (outside) from the
hub, be careful not to let the hub drop.
2. Remove the wheel bearing inner race (outside)
from the front hub by using special tool side
bearing puller (MB990810).
3. Install the inner race (outside) that was removed
from the hub to the wheel bearing, and then use
the following special tools to remove the wheel
bearing.
•Installer bar (MB990938)
•Installer adapter (MB990935)
•Knuckle arm bridge (MB991056 or MB991355)
