GENERAL INFORMATION Engine (Turbo)>
The evaporative emission control system preventsWhen driving with a low to medium load on the
fuel vapors generated in the fuel tank from escapin gengine, the fuel vapor absorbed by the EVAP
into the atmosphere.ter is drawn into the port of the throttle body.
Fuel vapors from the fuel tank flow through the When driving with a high load on the engine, the
fuel tank pressure control valve and vapor pipe/hos
epurge control valve opens and the fuel vapor

Caution
Before securely tightening the drive shaft nuts, ma ke
sure there isno load on the wheel bearings.

General Information/Service Specifications/
REAR AXLE Special Tools
The rear axle consists of a knuckle, rear hub, unit
bearing and axle shaft. The unit bearing is
fitted to the rear axle shaft and bolted to the knuckle.
Also, the unit bearing utilizes the same type of
double row angular contact ball bearing as does
the front axle.
On, ABS, a ABS rotor
for detecting the speed is located on the
and sensor is located on
the knuckle.
