Ford Focus>> Drive of forward wheels

The drive of forward wheels is intended for torque transfer from the engine through a transmission on naves of forward wheels (fig. 232) .
Both power shafts rather long: the right drive of forward wheels incorporates to a transmission through an intermediate shaft. Each of drives of forward wheels consists of a shaft and two hinges of equal angular speeds: internal and external. Hinges of equal angular speeds do not influence vibration of a steering wheel.
Noise in a drive of wheels testifies to their wear.
Service life of a drive of forward wheels substantially depends on a manner of your driving. Avoid sharp starts with the turned forward wheels. Noise in a drive of wheels signals about its defect, do not hope that over time they will disappear, and thoroughly be engaged in drive check.
Rhythmical percussions or crackling sounds which appear during acceleration or movement by breakthroughs (can change at turn of operated wheels), testify to the defective hinge from a wheel. Palpation of a steering wheel during turn — also a sign of defect of the external hinge.
At car dispersal with the turned forward wheels and having a defective drive of wheels the characteristic crash is found.

At the worn-out bearing of a nave of a wheel similar noise is shown.
