Parts for your 2004 Nissan Navara-Oil seals

2004 Nissan Navara oil seals

Yes, the 2004 Nissan Navara (D22) absolutely uses oil seals. This is confirmed in the Nissan Navara D22 Factory Service Manual—particularly the Engine Mechanical, Manual/Automatic Transmission, Transfer, Front/Rear Axle and Differential sections—which specify crankshaft front and rear oil seals, camshaft and rocker cover sealing, gearbox input/output shaft seals, transfer case output seals, and differential/axle and hub oil seals. The Nissan electronic parts catalogue for the 2004 D22 also lists these seals across the engine, driveline and axle assemblies, matching what major seal manufacturers catalogue for this model.

On a D22 Navara, oil seals do two key jobs: they keep engine, gearbox and diff oils where they belong, and they keep dust, water and grit out. They protect bearings and gears, stop oil from reaching places it shouldn’t (like a clutch disc or brake shoes), and help maintain proper lubrication and pressures. That’s especially important for utes that tow, work hard, or see corrugations, beach runs and creek crossings around Aus and NZ.

Where they live on a 2004 Navara:

• Engine: crankshaft front seal (behind the crank pulley) and rear main seal (between engine and gearbox)
