WHEEL SPEED SENSOR

REMOVAL AND INSTALLATION

M1357002200010

CAUTION

The wheel speed detection magnetic encoder collects metallic particles easily, because it is magnet-
ised. Inspect the wheel speed detection magnetic encoder for foreign material adhesion, and verify 
that there is no malfunction in the encoder before assembly.

NOTE: 

.

•

The encoder for detecting front wheel speed is a non-disassemble part integrated with the wheel bearing.

•

The encoder for detecting rear wheel speed is a non-disassemble part press fitted to the rear hub inner 
ring.

INSTALLATION SERVICE POINTS
