Fig. 9 Pressing the new anti-lock brake sensor rotor onto the drive shaft

Install the new anti-lock brake sensor rotor onto the drive shaft and press it on using the special tools (fig. 9).

Fill the boot (wheel side) with grease.

The covers on the side of the wheel and on the side of the gearbox are different.

Do not touch the grease with your hands.

Apply lube from the tube, keep contaminants out of the case.

Amount of grease: 90-110 g

Install the cover without removing the adhesive tape that was wrapped around the shaft splines during disassembly.

Remove the tape.

Align the marks made during removal and install the tripod using a rod and a hammer (fig. 10).

Install the new circlip using circlip pliers.

Make sure the circlip fits into the groove of the shaft

Fill the pivot housing and boot (gearbox side) with grease. Grease quantity: 195-215g

Fig. 11 Bleeding the covers with a screwdriver

Purge the air from the covers by prying up the edges of the smaller ends of the covers with a cloth-wrapped screwdriver (fig. 11).

Be careful not to leak grease.

Do not damage the covers. Make sure the length of the drive shaft is within specification.

Bend the clamp in the opposite direction of the rotation of the drive shaft when the vehicle is moving forward, and use a pair of pliers to tighten the clamp tightly.

Fig. 12 Fitting the boot strap (gearbox side)

Lock the end of the clamp by bending the locking clips (fig. 12).

Insert the collar securely into the groove.

Adjust gap "A" by turning the adjusting bolt of the special tool (fig. 13). Gap "A" : 2.9 mm

Fig. 13 Adjusting clearance "A" of the boot (wheel side)

Squeeze the small boot clamp on the side of the wheel using the tool. Check that the gap "B" is within the limits (Fig. 14).

Fig. 14 Adjusting clearance B of the boot (wheel side)

If gap "B" is too large, reduce the gap of the special tool and compress the boot again.

If clearance "B" is less than specification, replace boot clamp, increase special tool clearance and compress new boot.

Gap "B" : 2.4 - 2.8 mm. Make sure that the boot strap does not protrude from the boot strap installation area.

If so, replace the boot strap and reinstall. Fill the case with grease from the repair kit.

Adjust gap "B" by turning the adjusting bolt of the special tool.

Gap "B" : 3.2 mm. Make sure that the strap of the boot does not protrude from the installation area.
