GENERAL INFORMATION

M1271000100371

The rear axle has the following features:

• The wheel bearing is a unit ball bearing

(double-row angular contact ball bearing) for
reduced friction.

• The wheel bearing incorporates vehicle speed

detection magnetic encoder for ABS to reduce
the quantity of parts.

• The rear wheel hub assembly combines the hub,

wheel bearing, housing, and oil seal in a single
unit for fewer parts, better durability, improved
assembly precision, and better structural
organization.
