Front Axle -- Evolution: General Description: Notes

The front axle consists of front wheel hub assembly, 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 rigidity, improved assembly precision, and better structural organization.
• The drive shaft on wheel side incorporates EBJ type constant velocity joint.
• The drive shaft on differential side incorporates TJ type constant velocity joint.
• ABS rotor for detecting the wheel speed is press-fitted to the EBJ.
• For environmental protection, a lead-free grease is used on the joints.

EBJ:Eight Ball Fixed Joint; Due to the use of the smaller size eight balls inside the joint, this features weight saving and compact size compared with BJ (Birfield Joint).

TJ: Tripod Joint
