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
