Parts for your 2008 Nissan Pathfinder-Oil seals

2008 Nissan Pathfinder oil seals — what they do and when to replace

Oil seals are absolutely used on the 2008 Nissan Pathfinder (R51). Nissan’s 2008 R51 Pathfinder Factory Service Manual and the Nissan FAST electronic parts catalogue list multiple oil seals across the engine, transmission, transfer case and differentials, including front and rear crankshaft seals, axle and pinion seals, and transfer case input/output seals. So oil-seals are relevant to this model and a normal part of servicing and repairs.

On a Pathfinder, oil seals keep engine oil, gearbox fluid and diff oil where they belong, preventing leaks, contamination and premature wear. They sit at rotating shafts and housings, coping with heat, pressure and movement. When they harden, wear a groove, or are exposed to clogged breathers, they’ll weep or leak, which can lead to low fluid levels and bigger bills if ignored.

• Engine: front crankshaft seal, rear main seal (between engine and gearbox)
• Driveline: front and rear diff pinion seals, axle shaft seals
• Transfer case: input and output shaft seals (on 4x4 variants)

There’s no fixed replacement interval for oil seals
