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

MOOG 285 is a greaseable Super Strength universal joint engineered to replace worn U-joints on Toyota 4Runner and compatible Lexus models, offering greaseable bearings, corrosion protection, and heavy-duty construction.

When your driveshaft U-joint shows wear, upgrading to a MOOG Super Strength unit delivers improved durability and serviceability designed for higher torque and repeated use. MOOG designs these universal joints with cold-forged bearing cups, a carburized, heat-processed cross, and Nitrile seals to keep contaminants out while allowing routine greasing. The MICRO SHIELD coating helps resist rust so the part endures wet, salty, and off-road conditions common to 4Runner owners.

How does this U-joint improve driveshaft reliability?

The MOOG 285 emphasizes structural strength and contaminant exclusion to prolong drivetrain life. Cold-forged, case-hardened bearing cups and a heat-treated steel cross reduce wear and resist deformation under high loads. Nitrile seals and a radial grease pathway allow consistent lubrication to all bearing surfaces, minimizing premature failure.

• Cold-forged, precision-ground bearing cups for long life
• Carburized, heat-treated steel cross for higher torque tolerance
• Nitrile sealing to block dirt and retain grease
• Radial design for 360° grease distribution to bearing surfaces

Will this MOOG joint fit my Toyota 4Runner or Lexus?

MOOG 285 covers a wide set of Toyota 4Runner years and several Lexus models; always verify fitment before ordering. Use your vehicle year, make, model, engine and trim to confirm compatibility — some listings include additional notes in fitment tools. If in doubt, consult the vehicle-specific fitment guide or a trusted mechanic to match differential location and dimensions.

• Compatible with many Toyota 4Runner years (1984–2016 coverage listed)
• Also fits numerous Lexus LX and GX model years as specified
• Check vehicle information and fitment notes before purchase

What maintenance advantages does a greaseable U-joint provide?

A greaseable design gives you control over lubrication intervals, extending service life compared with sealed, non-greasable units. Regular greasing flushes contaminants away from bearing surfaces and replenishes lubricant, which is especially useful for vehicles used off-road, towing, or in harsh climates. MOOG’s radial grease distribution helps ensure lubricant reaches all rolling elements.

• Periodic greasing prolongs bearing life and prevents dry starts
• 360° grease distribution ensures even lubrication coverage
• Easier to maintain on vehicles with frequent heavy loads or off-road use

What protective features prevent corrosion and contamination?

MOOG applies its MICRO SHIELD coating to reduce rust formation on exposed metal surfaces, which helps the joint withstand moisture and road salt. Nitrile seals maintain grease inside while keeping mud and debris out, and the precision fit of cold-forged components minimizes gaps where contaminants could enter.

• MICRO SHIELD coating to help resist surface corrosion
• Nitrile seals for grease retention and contaminant exclusion
• Precision manufacturing reduces intrusion points for dirt and water

Who this is for: The MOOG 285 greaseable Super Strength U-joint is aimed at Toyota 4Runner owners, technicians, and off-road enthusiasts who need a heavy-duty, serviceable replacement for worn driveshaft joints. It’s suitable for drivers who tow, frequently traverse rough terrain, or prefer routine maintenance to extend drivetrain life. If you expect higher torque demands or want a rebuildable, grease-maintainable solution backed by engineering testing and corrosion protection, this MOOG unit is a practical choice.
