{"title":"Transfer Case \u003e Gaskets and Sealing Systems","description":"\u003cp\u003eTransfer case gaskets and seals prevent fluid loss at every rotating shaft and mating surface in your 4WD or AWD drivetrain. This category covers output shaft seals (the most commonly replaced item), input and main shaft seals, shift and selector shaft seals, adapter gaskets, extension housing seals, and low-volume specialty seals like the PTO shaft seal and actuator seal. Most fail gradually — lip seals harden and crack with age or heat cycles, while gaskets can weep after a fluid change disturbs old sealant. Transfer case fluid runs hot and thin, so even a minor leak accelerates wear on internal components. When buying, match the seal OD, ID, and width exactly — a 1–2mm mismatch causes immediate leakback. OEM seals from Timken, National, or your vehicle manufacturer are the safest fit; premium aftermarket options in PTFE or Viton hold up better under high heat than standard nitrile rubber, especially on trucks that see frequent towing or off-road use.\u003c\/p\u003e\n\n\u003ch3\u003eSigns you need replacement\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFluid puddle or wet film beneath the transfer case.\u003c\/strong\u003e A reddish or amber spot on the driveway — especially centered under the vehicle — typically points to an output or input shaft seal failure.

It's smart practice to inspect seals any time you drain and refill transfer case fluid, which should happen every 30,000–60,000 miles depending on manufacturer specs.\u003c\/li\u003e\n\n  \u003cli\u003e\n\u003cstrong\u003eAre OEM transfer case seals worth the premium over aftermarket?\u003c\/strong\u003e\n  For shaft seals, OEM or OEM-equivalent brands like National, Timken, or SKF are the better call — exact dimensional tolerances matter, and these manufacturers supply many OEM lines anyway. Generic no-brand seals frequently fail early. For gaskets, a quality aftermarket option using multi-layer steel or rubber-coated material is generally fine, since they're not under rotational stress.\u003c\/li\u003e\n\n  \u003cli\u003e\n\u003cstrong\u003eWhat else should I replace when doing an output shaft seal?\u003c\/strong\u003e\n  While you have the driveshaft dropped and the yoke off, replace both output shaft seals at the same time — front and rear — since they're the same age and the extra seal costs only a few dollars. Also inspect the slip yoke or companion flange for scoring; a grooved shaft surface will destroy a new seal within a few thousand miles and may require a speedi-sleeve repair collar.\u003c\/li\u003e\n\u003c\/ul\u003e","products":[{"product_id":"elring-469-120-transfer-case-input-shaft-seal","title":"Elring 469.120 Transfer Case Input Shaft Seal","description":"\u003ch2\u003eTransfer Case Input Shaft Seal for Audi and Volkswagen\u003c\/h2\u003e\u003cp\u003eThe Elring 469.120 transfer case input shaft seal is built for precise sealing at the transfer case input shaft.
