FAQ

How do I know my Ranger 1000 front differential seals are leaking?

Wet, oily residue around the axle or input seals, a low gear oil level at service, or drips under the differential are the usual signs.

What comes in the kit?

All Balls lists three O-rings and three seals per kit.

Which models does it fit?

Is installation difficult?

Seals can often be replaced with the output yokes or axles removed, using a seal puller and driver. Refill with the correct gear oil afterward and check for leaks. All Balls does not publish an install sheet for this kit.

Which position does it fit?

Should I buy the seal kit or the full bearing kit?
