CAN-AM RENEGADE 1000 Leak

Rear Axle Oil Seal

This radial lip seal prevents gear oil from escaping where the CV axles enter the differential housing. Failure typically occurs when debris enters the seal's outer lip, scoring the rubber or the mating surface of the axle, or when thermal cycling causes the seal to shift within its bore. Replacing the seal restores the pressurized elastomeric barrier required to retain the 75W140 synthetic lubricant.

Pinion Seal

The pinion seal maintains the integrity of the differential at the input shaft where it connects to the driveshaft. It is subject to high rotational speeds and vibration; axial play in the pinion bearings or debris entanglement (like tall grass or fishing line) can compromise the seal's inner diameter. Replacing this part is the standard fix for leaks identified at the front nose of the rear differential.

Differential Expansion Tube

The differential is a vented system that uses an expansion tube to equalize pressure as the internal air and oil heat up during operation. If this tube is pinched, clogged with mud, or torn, the resulting internal pressure will force oil past the axle or pinion seals even if the seals themselves are not damaged. Replacing a damaged vent line addresses the root cause of 'phantom' leaks and prevents vacuum-induced water ingestion during submersion.
