GENERAL INFORMATION

M1261000100444

The front axle consists of front wheel hub assembly, 
knuckles and driveshafts, and has the following fea-
tures:

• The wheel bearing incorporates a unit ball bear-

ing (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 driveshaft on wheel side incorporates an EBJ 

type constant velocity joint.

• The driveshaft on the differential side incorpo-

rates a 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; The use of the 

smaller-sized eight balls inside the joint achieves 
weight saving and compact size compared with a 
BJ (Birfield Joint).

TJ: Tripod Joint
