Front Axle: General Description: Notes

The front axle consists of front hub unit bearings, knuckles and drive shafts, and it has the following features:

• The wheel bearing incorporates a unit ball bearing (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 drive shaft incorporates BJ-TJ type constant velocity joints < 2.4L engine > and EBJ-PTJ type constant velocity joints <3.8L engine> with high transaxle 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.<3.8L engine-RH>
• The dynamic damper is mounted on the LH drive shaft < all models > and on the RH drive shaft < 2.4L engine > to reduce differential gear noise.
• ABS rotor for detecting the wheel speed is press-fitted to the BJ < 2.4L engine > and EBJ < 3.8L engine >.

BJ : Birfield Joint

TJ : Tripod joint

EBJ (Eight Ball Fixed Joint) : The use of the smaller size eight balls inside the joint achieves weight saving and compact size compared with BJ.

PTJ : Pillow Tripod Joint
