Hub carrier bearing

This method requires the following tools:

• tool (Rou. 15-01),
• tool (Rou. 604-01),
• tool (Tav. 476),
• tool (Tav. 1050-02).

The bearing is instrumented. Take care not to damage the wheel speed sensor target when refitting.

REMOVAL

• Remove the hub carrier (see Front Structural Components, Hub carrier, page 31A-10).

F4R or K4J or K4M

• Remove:

• the hub, using a press, supporting it with a 36 mm diameter tube,
• the outer race of the hub carrier bearing, supporting it with a tube of the same diameter as the outer race,

F4R or K4J or K4M

• Remove the inner race of the hub using a 41 mm diameter tube as support.

F9Q or K9K

• Remove:

• the hub, using a press, supporting it with a 41 mm diameter tube,
• the outer race of the hub carrier bearing, supporting it with a tube of the same diameter as the outer race.

• Remove the inner race of the hub using a 46 mm diameter tube as support.

INSTALLATION

• Always check the surface condition of the hub and the hub carrier bore before refitting the bearing.
• Replace the hub carrier if it is defective.
• Clean:

• the inner and outer surfaces of the new bearing that contact the hub carrier and the hub,
• the hub carrier surfaces in contact with the new bearing,
• the hub surfaces in contact with the new bearing.

• Do not press on the inner race of the bearing to avoid damaging it (very high press-fitting force).

• Refit the sensor holder.
• Position the sensor holder at (x) = 35 +/− 5 from the vertical. This position corresponds to the centre of the housing.

F4R or K4J or K4M

• Support the outer race with a tube of 72 mm outside diameter and 65 mm bore diameter.

• Refit the circlip.
• Check that the circlip is correctly seated by measuring the inside diameter (X1) = 61.6 mm for a bearing with an outside diameter of 72 mm.

F9Q or K9

• Support the outer race with a tube of 77 mm outside diameter and 70 mm bore diameter.

• Refit the circlip.
• Check that the circlip is correctly seated by measuring the inside diameter (X1) = 67.6 mm for a bearing with an outside diameter of 77 mm.

• Refit:

• the hub,
• the "hub carrier - bearing - hub" assembly (see Front Structural Components, Hub carrier, page 31A-10).

• Tighten to the following torques:

• the lower ball joint bolt (6.2 daN.m),
• the steering ball joint nut (3.7 daN.m),
• the driveshaft nut (28 daN.m),
• the shock absorber foot bolt (10.5 daN.m),
• the disc retaining bolt (1.5 daN.m),
• the caliper bracket bolt (10.5 daN.m),
• the wheel bolt (11 daN.m).
