The differential is the housing at the front or rear of the quad that turns the propeller shaft’s drive towards the wheels, using gears that run in oil.

Why a bearing and seal kit?

The benefits:

• All the wear parts in one order, without tracking down each bearing and seal.
• Get back a sealed, quiet axle without replacing the whole differential.
• Protect the gears, the most expensive part of the axle, by stopping water in time.

Why choose ALL BALLS?

Complete All Balls kits: low-friction bearings and steel-spring nitrile seals, everything you need in one box.

When should you replace this part?

Oil seeping round the seals, milky oil (water has got in), a growl or play in the axle: rebuild the differential.

• Manufacturer part number: 25-2100
