MOOG premium greaseable universal joint for Chevrolet Silverado 1500 — 330 model, zerk-fitted, heavy-duty forged construction

MOOG 330 is a greaseable premium universal joint engineered to restore smooth drivetrain operation and extend service life in compatible trucks.

Designed and validated by MOOG engineers, this greaseable universal joint replaces worn factory U-joints with a heavy-duty assembly built from cold-forged bearing cups, a carburized steel cross and nitrile rubber seals. The greasable design allows periodic lubrication to purge contaminants, while precision-ground components reduce vibration and wear for dependable performance during towing, hauling or daily driving.

How does the greaseable design improve longevity?

Adding a grease fitting gives you the ability to inject fresh lubricant and push out trapped dirt and moisture, which slows corrosion and bearing wear. Routine greasing can be a simple maintenance step that avoids premature replacement.

• Zerk fitting for straightforward grease application
• Flushes debris and moisture from bearing surfaces
• Extends seal life by keeping contaminants away
• Reduces friction for smoother drivetrain operation

What construction features make this U-joint reliable?

MOOG builds the 330 with components processed for strength and dimensional accuracy. The cross is forged and carburized, bearing cups are cold-forged and precision ground, and seals use a compressed double-lip nitrile rubber design to resist contaminants.

• Forged, carburized steel cross for high fatigue strength
• Cold-forged, case-hardened bearing cups for longevity
• Precision grinding for balanced, low-vibration operation
• Nitrile double-lip seals to keep dirt and water out

Which vehicles and fitment should I confirm before buying?
