Differential output seal

JH3 or JR5

REMOVAL

• Position the vehicle on a two-post lift.
• Disconnect the battery, starting with the negative terminal.
• Remove the undershield.
• Drain the gearbox oil.
• Remove:

• the wheel,
• the mudguard,
• the hub nut,
• the steering ball joint,
• the stabilizer bar ball joint,
• the lower ball joint.

• Disconnect:

• the wheel speed sensor connector,
• the xenon headlamp levelling sensor wiring (if fitted).

• Remove the relay bearing bracket.

• Remove the driveshaft.

SEAL REPLACEMENT

• Tap the oil seal on the base using a pin punch and a small hammer to rotate it in its housing.
• Remove the dislodged seal with pliers, taking care not to damage the splines of the differential side gear.

INSTALLATION

• Lubricate the seal.
• Refit the seal using tool (Bvi. 1666) (index A: right side, index B: left side).
• Position the driveshaft in relation to the differential side gear.
• Refit in the reverse order of removal.
• Tighten to the following torques:

• wheel mounting bolts (11 daN.m),
• the lower ball joint nut (6.2 daN.m),
• the steering ball joint nut (3.7 daN.m),
• stabilizer bar ball joint nut (4.4 daN.m),
• the hub nut (28 daN.m),
• relay bearing bracket nut (2.1 daN.m),
• engine torque rod bolts (10.5 daN.m),
• subframe torque rod bolts (10.5 daN.m).

• Check the gearbox oil level.

Connect the battery; carry out the necessary relearn procedures (see Battery chapter).

• Torque the battery cover (0.4 daN.m).
