SYSTEM CHECK SOUND When starting the engine, a thudding sound can sometimes be heard coming from
the engine compartment. This is a normal sound during the ABS self-check. ABS OPERATION SOUNDS AND SENSATIONS During normal operation, the ABS makes several sounds that may seem unusual at
first:
A whining sound is caused by the ABS hydraulic unit motor. When pressure is applied to the brake pedal, the pulsation of the pedal causes a
scraping sound. When the brakes are applied firmly, the ABS operates, rapidly applying and
releasing the brakes many times per second. This repeated application and
release of braking forces can cause the suspension to make a thumping sound
and the tires to s
queak.

4. To observe the waveform with an oscilloscope:
Front Wheels: Shift into "D" range and drive the wheels. Rear Wheels: Turn the wheels manually at a constant speed
POINTS IN WAVEFORM MEASUREMENT Fig. 150: Identifying Points In Waveform Measurement

Courtesy of MITSUBISHI MOTOR SALES OF AMERICA. NOTE: The output waveform is low when the wheel speed is low.
Similarly, it will be higher as the wheel speed increases.
Waveform may also be observed by driving the vehicle.
NOTE: The ABS sensor cable moves in relation to motion of the
front or rear suspension. Therefore, it is likely that it has an
open circuit only when driving on rough roads but it
functions normally when driving on smooth roads. It is
recommended to observe sensor output voltage waveform

.
C. Using Bar (Snap-In Type) (MB990938) and Installer Adapter (MB990932),
press-fit the center bearing into the center bearing bracket. See Fig. 18
.
D. Apply the specified great (from the repair kit) to the rear surface of all dust
seals. Using Rear Suspension Bushing Base (MB990890), Bar (Snap-In type)
(MB990838), and Installer Adapter (MB990934), press the dust seals into the
center bearing bracket until they are flush with each other. See Fig. 19 . Apply
repair kit grease to the lip of each dust seal.
E. Using Inner Shaft Installer Base (MB991172), hold the center bearing inner
race, and then press-in the inner shaft. See Fig. 20
. Apply repair kit grease to
the inner shaft spline, then press-fit it into the PTJ case.
F. After applying the specified grease to the PTJ case, insert the axle shaft and
apply grease again.
G. Set the PTJ boot bands at the specified distance to adjust the amount of air
inside the PTJ joint, and then tighten the small and large PTJ boot bands. See
Fi
g. 12
. CAUTION: When applying grease, make sure that it does not
adhere to anything outside the lip.
NOTE: When press-fitting the inner shaft into the PTJ case,
apply a thin coat of repair kit grease to the dust seal
outer lip part and the outside edge of the PTJ axial part.
CAUTION: The axle shaft joint uses special grease. DO NOT
mix old, new, or different types of grease.
NOTE: The grease in the repair kit should be divided in half for
use, respectively, at the joint and inside the boot.

2004 Mitsubishi Endeavor LS 2004 SUSPENSION Front - Endeavor

If the front suspension is faulty, the vehicle will not run straightforward or noise
will occur. Incorrect wheel alignment, malfunction of strut assembly, stabilizer bar,
coil spring, or worn or out-of-balance tires can cause these problems. FRONT SUSPENSION DIAGNOSIS TROUBLESHOOTING STRATEGY Use these steps to plan your diagnostic strategy. If you follow them carefully, you
will be sure that you have exhausted most of the possible ways to find a front
suspension fault.
