In this case, the front right wheel bearing was replaced on a Ford Focus Mk2. The symptom of a failed bearing was a humming noise when driving at high speed.

  • Further instructions on wheel bearing replacement and tool lists can be found here;
  • Replacement video here.
The standard factory service life of a wheel bearing is 70,000–80,000 km.

To carry out the replacement procedure, you will need a new hub assembly, as on the Ford Focus Mk2, the bearing and hub are a single unit (GEN2 non-serviceable unit). The exception is cars with rear drum brakes, but here we are discussing the front axle.

Pay special attention to the ABS sensor located on the front steering knuckle. There is a risk of damaging it when replacing the wheel bearing.

Ford Focus Mk2 hub part numbers

The choice of hub depends on availability and brand preference. The original hub has part number 1471854. Popular aftermarket options include: Pilenga HB-P 5489, GMB GH21190 or Fenox WHB71111.

How to change the wheel bearing on a Ford Focus Mk2

You will need a set of spanners and sockets (sizes 12, 13, 15, 17, 21), Allen keys, Torx T50, as well as a press and mandrels. The ideal option is a special kit for pressing out GEN2 bearings (allows replacement directly on the car without a press).

CRITICALLY IMPORTANT: the hub must be pressed in strictly via the outer race (or using a special mandrel on the flange). Pressure on the inner part of the hub, as is often done on conventional bearings, will immediately destroy the new unit.

Removal of the front hub and replacement of the wheel bearing on the Ford Focus Mk2 are shown in detail in the photos below.

Step 1
1

Remove the front right wheel.

Step 2
2

Before replacing the Focus Mk2 hub, clean the thread on the track rod end of dirt and apply penetrating oil.

Step 3
3

Undo the track rod end nut.

Step 4
4

Use a specific puller for ball joints and rod ends.

Step 5
5

Carefully install the puller on the track rod end to avoid damaging the rubber gaiter.

Step 6
6

Press out the track rod end.

Step 7
7

Unscrew the drive shaft retaining bolt using an impact wrench (or a breaker bar with an extension).

Step 8
8

Remove the brake hose from its mounting on the shock absorber.

Step 9
9

Undo the two bolts securing the brake caliper carrier.

Step 10
10

Remove the brake caliper together with the carrier.

Step 11
11

To avoid damaging the brake hose, suspend the caliper from a spring coil using wire or a cable tie.

Step 12
12

Remove the brake disc.

Step 13
13

Clean the thread and apply penetrating lubricant to the ball joint pinch bolt.

Step 14
14

Undo the nut with a ring spanner. It is very important that the thread is clean, otherwise the ball joint pin may be damaged, leading to its replacement.

Step 15
15

Press the ball joint out of the steering knuckle using the same puller.

Step 16
16

Unscrew the pinch bolt securing the steering knuckle to the shock absorber.

Step 17
17

Remove the loosened bolt from the hole.

Step 18
18

Remove the steering knuckle. You may need a spreading tool or chisel to slightly open the clamp on the shock absorber.

Attention! If the car is equipped with an ABS system, the ABS sensor must be disconnected before removing the knuckle (in this example, the model is without ABS).

Step 19
19

The removed steering knuckle.

Step 20
20

Clean dirt from the removed part.

Step 21
21

It is essential to use the correct tools to replace the Ford Focus Mk2 front wheel bearing.

This photo shows an example of crude removal: the edges of the hole are bent from blows with a blunt object. Do not do this.

Step 22
22

A hydraulic press for bearing replacement.

Step 23
23

Place the steering knuckle under the press using spacers of the appropriate diameter.

Step 24
24

With the press ram pushing against the face of the hub, carefully press out the old unit. It is important that it comes out evenly, without tilting.

Step 25
25

The pressure required for removal can reach high values.

Step 26
26

It is best to support the hub from below so that it does not fall onto your feet when it exits the knuckle.

Step 27
27

The old and new hub bearing assembly.

Step 28
28

Turn the steering knuckle over and set it horizontally under the press. The mounting bore must be cleaned and greased.

Step 29
29

Place the hub bearing into the mounting bore.

Step 30

WARNING, ERROR IN PHOTO!
The image shows pressure being applied to the inner part of the hub — this is UNACCEPTABLE for a new bearing (it will lead to failure).

You must press only on the outer race of the bearing or use a special mandrel for GEN2 hubs.
Step 31
31

The new hub is pressed into the steering knuckle as far as the retaining ring.

Step 32
32

Reinstall the steering knuckle on the car in reverse order.

Step 33
33

Tighten all bolts using a torque wrench. Torque settings for Ford Focus Mk2:

  • Hub bolt (drive shaft): 45 Nm, then tighten by a further 90°.
  • Knuckle to shock absorber bolt: 90 Nm.
  • Ball joint nut: 50 Nm.
  • Track rod end nut: 48 Nm.
Step 34
34

Refit the wheel and lower the car from the lift.
