{"product_id":"oil-seal-diff-pinnion-186675","title":"Oil Seal - Diff Pinnion for Series 2 \u0026 2A Rovber type axles – FRC4586","description":"\u003cp\u003eFRC4586 is the pinion oil seal for the differential on Rover-type axles fitted to Series and early Defender Land Rovers. It seats at the nose of the differential, preventing gear oil from escaping past the pinion shaft where it enters the axle casing. A worn or hardened seal results in oil loss from the diff nose, often visible as a trail of oil beneath the front or rear axle - left unaddressed, this leads to low diff oil levels and accelerated pinion bearing wear.\u003c\/p\u003e\n\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eLip-type rotary oil seal designed to retain differential gear oil at the pinion shaft\u003c\/li\u003e\n\u003cli\u003eCorrect fitment requires clean seal housing and inspection of the pinion flange for wear grooves before installation\u003c\/li\u003e\n\u003cli\u003eMatches OEM specification for Rover-type axles as fitted across Series 2, 2A, Series 3, and early Defender 90 applications\u003c\/li\u003e\n\u003cli\u003eReplace the pinion flange nut and check companion flange condition when fitting - one seal required per axle\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch4\u003eVehicle Fitment\u003c\/h4\u003e\n\u003cp\u003eFits Series 2 \u0026amp; 2A (Rover-type axles), Series 3 with 2.25 Petrol, 2.6 6-cylinder and 3.5 V8 engines (excluding 109 1-Ton variants), and Defender 90 models from 1983 up to axle number 22S08283B.\u003c\/p\u003e\n\u003cp\u003eNot sure about fitment?
