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.
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).
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.
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.

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.
