Maintaining the integrity of wheel end and axle assemblies is crucial for safe and efficient truck operation. As a premier supplier of durable and reliable Foton truck parts, we present the essential Nave Oil Seal, precisely identified by the OEM part number 99000410061. This critical sealing component is designed to prevent lubricant leakage and block contaminants from entering the wheel hub or axle assembly on FOTON trucks. The specific seal, part number 99000410061, ensures that grease stays in and dirt, water, and debris stay out, protecting vital bearings and ensuring smooth, friction-free rotation of the wheels for thousands of miles.

The Nave Oil Seal, part number 99000410061, is a precision sealing device installed at the point where a rotating shaft (such as an axle shaft or spindle) enters a stationary hub or housing. Its dual-purpose function is vital for longevity.
First, it retains the lubricating grease or oil within the wheel bearing cavity. This continuous lubrication is essential to prevent metal-to-metal contact, reduce friction, and dissipate heat from the bearings. A failed seal, including part 99000410061, allows grease to escape, leading to rapid bearing wear, overheating, and potential wheel-end seizure.
Second, it acts as a barrier against external contaminants. Road dust, mud, water, and salt are aggressively kept out. Preventing these elements from contaminating the bearing grease is equally important, as contamination turns the lubricant into an abrasive paste that accelerates component failure.
The 99000410061 oil seal is a sophisticated component. It typically consists of a metal outer shell that is pressed into the stationary hub, providing structural rigidity and ensuring the seal remains in place.
Bonded to this shell is the primary sealing element—a flexible lip made from a specialized elastomer. A garter spring (a small coiled wire) is often embedded around the lip to apply constant radial pressure against the shaft, compensating for minor shaft run-out and lip wear over time.
Some advanced designs may include a secondary dust lip. This outer lip provides an additional barrier against large particulate contaminants, further protecting the primary sealing lip and extending the service life of the entire seal assembly, part number 99000410061.
A failing Nave Oil Seal, part number 99000410061, presents clear warning signs. The most obvious is grease visibly slung onto the inside of the wheel rim or dripping from the hub area.
Contaminant ingress often leads to a grinding or rumbling noise from the wheel, especially during turns, indicating bearing damage. In severe cases, the wheel hub may become abnormally hot to the touch after driving due to lack of lubrication.
Ignoring a leaking seal allows grease loss, leading to bearing failure. A seized bearing can damage the axle spindle and hub, resulting in a costly repair bill and significant vehicle downtime. Proactive replacement of the 99000410061 seal during brake or bearing service is a wise preventive measure.
The table below details the core technical specifications for the genuine FOTON Nave Oil Seal. This data is essential for parts identification and application verification.

Correct installation of the Nave Oil Seal, part number 99000410061, is critical for its performance and longevity. The hub or axle assembly must be disassembled, and the old seal completely removed using a suitable seal puller to avoid damaging the sealing bore.
The sealing bore in the hub must be meticulously cleaned of any old seal material, rust, or debris. The new seal, 99000410061, should be lightly lubricated on the outer metal casing and the sealing lip with the same grease used for the wheel bearings.
Using a seal driver or a socket of the appropriate size, the seal must be driven squarely into the bore until it seats fully and evenly. Driving it in at an angle will distort the seal, causing an immediate leak. The sealing lip must face inward, toward the grease cavity. After installation, the bearings should be repacked with fresh grease before reassembly.
Regular inspection of wheel end seals, including 99000410061, can prevent major repairs and ensure safety.
Visual Inspection: During tire rotations or brake inspections, look for signs of grease leakage on the inner side of the wheel or around the hub area. Check for any tears or nicks on the visible part of the seal.
Bearing Check: Whenever a seal is suspected of leaking, the wheel bearings must be inspected for contamination (gritty grease), discoloration from overheating, or any signs of pitting or spalling.
Preventive Replacement: It is standard practice to replace the nave oil seal whenever the wheel bearings are serviced or replaced. The cost of the seal (part 99000410061) is minimal compared to the labor and cost of a bearing failure caused by a leak.
Shaft Condition: Before installing a new seal, inspect the sealing surface of the axle shaft or spindle for grooves, rust, or scoring. A damaged shaft will quickly ruin a new seal. A repair sleeve may be required in such cases.
The 99000410061 seal is engineered for specific FOTON truck models and axle configurations. Using the correct OEM part number is essential because the shaft diameter, bore diameter, and seal width are precisely matched to the application.
An incorrect seal, even if it fits physically, may not provide the correct lip tension or may not seat at the proper depth, leading to premature failure. Always cross-reference the part number with your vehicle’s VIN or consult a compatibility chart.
For trucks with dual rear wheels or specific heavy-duty axles, the sealing requirements are particularly stringent. The genuine part 99000410061 is designed to meet these specific demands, providing reliability under high load and temperature conditions.
The material composition and manufacturing precision of the 99000410061 seal are critical. Genuine FOTON seals use rubber compounds formulated to remain flexible and resistant to cracking in a wide temperature range.
Aftermarket seals may use inferior compounds that harden prematurely or have inconsistent lip dimensions, leading to leaks. The quality of the metal casing and the bond between the rubber and metal are also superior in OEM parts, ensuring the seal stays intact when pressed into the hub.
Investing in the genuine seal guarantees that the component will perform as intended for the expected service interval, protecting more expensive downstream components like wheel bearings and axles.
The Nave Oil Seal, OEM part 99000410061, is a classic example of a small, inexpensive component that plays an outsized role in vehicle reliability and safety. Its failure can lead to the catastrophic failure of critical wheel-end components.
Choosing the genuine FOTON part ensures optimal material quality, precise dimensions, and reliable performance. It is the definitive choice for maintaining the integrity of your truck’s wheel hubs, ensuring smooth operation, and preventing costly roadside breakdowns.
