GENERAL DESCRIPTION

M2270000100069

The rear axle has the following features:

The wheel bearing incorporates a unit ball bear-
ing (double-row angular contact ball bearing) for 
reduced friction.

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 organi-
zation.

ABS rotor for detecting the wheel speeds is 
press-fitted to the rear hub in vehicles with ABS.

SPECIFICATIONS

NOTE: The wheel bearing is part of the hub, there-
fore its size is not listed here.

GENERAL DESCRIPTION

M2230000100269

For the automatic transaxle, F4A4B and F4A5A 
models are used. On the F4A5A transaxle, the con-
ventional transmission fluid cooler (fluid-cooled and 
air-cooled) is used to improve transmission fluid 
cooling performance. On the F4A4B transaxle, a 
newly developed ATF warmer (transmission fluid 
cooler) is used.
