The front axle consists of front hubs, knuckles, wheel
bearings and driveshafts, and has the following fea
-
tures:
•The wheel bearing is a double-row angular con-
tact 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
