• Fits 2011–2018 Ram 3500 and select 2010–2012 Dodge/Ram 2500, 3500, 4500 models
• Always cross‑check the seller’s fitment tool and notes before purchase

How does the greaseable design benefit maintenance?

The MOOG 479 features drilled and tapped grease fittings and internal grease channels to make scheduled lubrication simple and effective. Regular greasing reduces wear, helps prevent dry starts, and extends the life of bearings and trunnions under heavy loads.

• Greaseable cross trunnions with radial channels for even grease distribution
• Large internal reservoirs hold lubricant where it’s needed most
• Internal valve in thrust washer controls lubrication flow to prevent over/under greasing

What construction features improve durability and performance?

This U‑joint is manufactured with cold‑formed, case‑hardened bearing cups and precision‑ground components to withstand harsh duty cycles. Nitrile seals keep contaminants out while a finely finished cross surface minimizes microscopic wear points.

• Bearing cups are cold‑formed, case‑hardened and precision ground for strength
• Nitrile seals provide superior grease retention and dirt protection
• Cross trunnions ground to a 15–25 RMS finish to inhibit premature wear

What testing and quality controls back the MOOG 479?

MOOG applies comprehensive engineering tests during design and development to validate fit, durability, and lubrication behavior. Those tests help ensure you receive a repeatable, reliable replacement part for heavy‑duty service.

• Design and development testing by MOOG engineers for real‑world durability
• Material and finish specifications target fleet and off‑highway reliability
• Serviceable features tested for ease of maintenance and longevity

Who is this for: The MOOG 479 greaseable universal joint is intended for technicians, fleet managers, and owners of Ram 2500/3500 and related heavy‑duty Dodge/Ram trucks who need a durable, serviceable driveline component.
