MOOG 479 Greaseable Premium Universal Joint for Ram 2500 - Durable OEM

In this review of the MOOG 479 Greaseable Premium Universal Joint, the bottom line is clear: it is a robust replacement for owners of heavy-duty Ram and Dodge trucks who need a durable, serviceable U-joint. Built for fleets and commercial use, this universal joint stands out for its greaseable design and engineered bearing cups that promise long service life. The review focuses on fit, durability, and serviceability, and highlights the practical value for technicians and owners who want a repair part engineered to resist contamination and simplify routine maintenance.

Key Features

• Compatibility: Fits a range of Ram 2500, Ram 3500 and Dodge Ram heavy duty models from the 2010 to 2018 model years, providing direct-replacement convenience for those trucks.
• Greaseable design: Drilled and tapped grease fitting holes and large grease reservoirs make routine servicing straightforward and help extend joint life.
• Durable bearing cups: Bearing cups are cold-formed, case-hardened and precision ground to improve strength and resist wear under heavy loads.
• Seal protection: Nitrile seals retain grease effectively and keep dirt and under-vehicle debris out of moving parts for better longevity.
• Controlled lubrication: An internal valve in the thrust washer regulates grease flow to inhibit dry startup and uneven lubrication.
• Engineered finish: Cross trunnions are ground to a smooth 15-25 RMS finish to reduce microscopic grooves that can accelerate wear.

Who It's For

This universal joint is aimed at owners and mechanics working on heavy-duty Ram 2500, Ram 3500 and similar Dodge Ram trucks who require a rugged, serviceable replacement part. Fleet managers, off-highway operators, and anyone who performs routine grease maintenance will appreciate the removable grease fittings and radial channels that aid distribution.

Owners of light-duty vehicles, or those with applications outside the listed model years and trims, should verify fitment carefully before purchasing and may want to consider a different U-joint designed specifically for passenger cars or newer truck models. Also check compatibility notes for exact engine and trim matches.
