In this case, the right front wheel bearing has been replaced on Ford Focus 2. A reason for the fault bearing has been a buzz when driving at high speed.
Factory lifetime of a wheel bearing is 70-80 thousand km.
For the replacement procedure, you will need a new hub, since you should not forget that the Ford Focus 2 bearing with the hub is one piece (non-separable assembly, with the exception of cars with rear brakes of the drum type).
Particular attention should be paid to the ABS indicator, which is located on the front clutch. During replacement of the wheel bearing there is a risk to break it down.
You will need a small set of wrenches: 12, 17, 21, a pair of Allen wrenches, as well as a set for pressing out and a hammer.
It is worth paying attention to one important note — it is necessary to press in the hub not not through the inner shell, as shown in the picture, а through the outer one. This error threatens to break down the bearing.
Left front wheel is removed.
Thread of tie rod is cleaned from dirt and lubricated with penetrating grease.
Nut of tie rod is loosened.
Special puller for tips and levers.
Puller is carefully mounted on tie rod not to break down duster.
Tie rod is pressed out.
With the help of an inflation gun, the drive bolt is unscrewed.
Brake hose is pulled out from fastening on the shock-absorber.
Two mounting bolts of the brake caliper are loosened.
Brake caliper is removed with attachment clip.
In order not to break down the brake hose, the caliper is suspended using a disposable clamp for the lower coil of the spring.
Brake rotor is removed.
Thread is cleaned and ball screw is lubricated with penetrating grease.
After that nut is unscrewed by box wrench. Thread should be necessarily cleaned, otherwise it is possible to break down the ball joint, which leads to its replacement.
With the same puller, the ball joint is pressed out of the steering knuckle.
Bolt of the trunnion is unscrewed by the inflation gun to the shock absorber.
Unscrewed bolt is pulled out of the hole.
After that, the knuckle is removed, you will need a special tool for removal because the pin is very tight on the shock absorber.
Attention! If a car is equipped with ABS system, it is necessary to disconnect the ABS sensor before removing the knuckle. This car does not equipped with ABS.
Unmounted steering knuckle.
Removed spare part is washed at the car wash.
To replace the wheel bearing, it is necessary to use a special tool. Its absence can lead to the following results:
This picture shows the result of an incorrect attempt to remount the wheel bearing (the edges of the hole are bent because of the heavy shock with a blunt instrument).
The press for replacing and press-fitting bearings.
With the help of special spacers, the steering knuckle is installed under the press.
Pressing the press stem into the center of the bearing, it is gently pressed out. It is important that it comes out evenly without sideways.
The pressure required for bearing press out is about 19 MPa (2700 psi).
It is better to hold the wheering hub from below so that it does not fall to someone`s feet.
Old and new hub are assembled with bearing.
Rotary pin is turned over and is installed horizontally under the press.
The hub bearing is fitted into the mounting bore.
The bearing is pressed in smoothly and without sideways in the steering knuckle. The force required to press in the bearing is 2600 psi.
Please note that the spacer is mistakenly put on the inner clip in the picture, while, in fact, it should be placed on the outer.
The new hub is pressed into the steering knuckle.
The steering knuckle is mounted on the vehicle in the reverse order.
All bolts are pulled by the appropriate tightening torques set by the manufacturer using a torque wrench.
The wheel is screwed and the car is lowered from the lift.
