MOOG Super Strength Greaseable Universal Joint for Toyota 4Runner — Model 285, Greaseable & Corrosion-Resistant

The MOOG 285 greaseable Super Strength universal joint is a heavy-duty replacement U-joint engineered to restore driveline reliability for Toyota 4Runner and compatible Lexus models while allowing on-vehicle lubrication.

Designed and tested with rugged materials and practical serviceability in mind, this MOOG Super Strength U-joint combines corrosion protection, a greaseable bearing design, and reinforced metallurgy to handle higher torque applications. It installs as a direct-fit replacement for many Toyota and Lexus applications and is intended for owners who need a long-lasting, serviceable driveline component that resists contamination and wear.

How does this MOOG U-joint improve durability under heavy use?

The 285 Super Strength U-joint uses cold-forged, case-hardened bearing cups and a forged, carburized cross to resist fatigue and impact. Those manufacturing steps increase surface hardness and core toughness so the joint withstands higher torque and repeated loading without premature failure.

• Cold-forged bearing cups for improved wear resistance
• Forged, carburized cross for higher tensile strength
• Precision ground components for balanced operation
• Engineered for applications with elevated horsepower and torque

Why choose the greaseable version — what are the service advantages?

This greaseable design lets you replenish lubricant while the U-joint remains installed, extending component life and maintaining smoother operation. A radial bearing cup design disperses grease evenly across all contact surfaces, improving lubrication coverage compared with non-greasable units.

• 360° radial grease distribution to all bearing surfaces
• On-vehicle lubrication reduces tear-down time and service cost
• Helps restore lost grease in long-running or older driveline systems

How does MOOG protect the joint from corrosion and road debris?

MOOG applies an exclusive protective coating to fight rust and uses nitrile seals to keep contaminants out while retaining grease inside. Those seals block moisture and under-vehicle debris, helping the joint maintain consistent lubrication and preventing abrasive contamination from accelerating wear.

• MICRO SHIELD coating resists corrosion on exposed metal surfaces
• Nitrile seals preserve grease and block dirt and water intrusion
• Durable finish extends service life in wet or salty environments

Is this the correct fit for my vehicle and how do I confirm compatibility?

The MOOG 285 covers many Toyota 4Runner and multiple Lexus LX/GX model years, but fitment depends on year, engine, and trim. Always verify fit using your vehicle details in the seller’s compatibility tool and review any manufacturer notes before purchasing.

• Fits late-model Toyota 4Runner years and several Lexus LX/GX generations
• Check vehicle year, make, model, engine and trim for match
• Refer to compatibility notes or the seller’s confirmed-fit indicator

Who is this for: The MOOG 285 greaseable Super Strength U-joint is suited to DIY mechanics, professional technicians, and off-road enthusiasts seeking a serviceable, corrosion-resistant replacement for worn or failed driveline U-joints. It’s especially appropriate for drivers who run high-torque setups, tow frequently, or operate vehicles in harsh conditions and want the option to refresh lubricant without removing the joint.
