Parts for your 2009 Nissan Pathfinder-Oil seals

2009 Nissan Pathfinder oil seals — what they do and how to look after them

Yes, oil seals absolutely are used on the 2009 Nissan Pathfinder (R51). Technical documentation such as the Nissan R51 Factory Service Manual (sections EM, AT/MT, TF and DLN) and the Nissan electronic parts catalogue list multiple seals across the vehicle: front and rear crankshaft seals, camshaft seals on the VQ40DE petrol, axle and pinion seals in the diffs, and input/output shaft seals in the transmission and transfer case. So oil seals are very much relevant to this model.

On this Pathfinder, oil seals keep lubricants where they belong and dirt out of the works. They maintain correct oil levels in the engine, transmission, transfer case and differentials, protecting bearings, chains/gears and clutches. The YD25 diesel and VQ40 petrol both rely on a front crank seal at the harmonic balancer and a rear main seal behind the flywheel/flexplate
