Details About Universal Joint 4301-3401485
Function
The universal joint (also called a cardan joint) connects the driveshaft to the transmission and axle, allowing torque to be transmitted at different angles while accommodating suspension movement.
Key Features
Cross-type joint with needle bearings for durability. Designed for high torque and frequent load changes typical in commercial vehicles. May include grease fittings for lubrication.
Common Symptoms of Failure
Vibrations while driving (especially at higher speeds).
Clicking or clunking noises when shifting gears or accelerating.
Excessive play in the driveshaft.
Inspection & Maintenance
Visual Inspection
Look for cracks, rust, or grease leaks.
Check if the grease fittings (if present) are intact.
Manual Play Test
Rotate the driveshaft by hand—there should be no excessive free play.
Try moving the joint up/down/sideways—if it moves more than 1-2 mm, it’s likely worn.
Lubrication
Some U-joints have zerk fittings—use a grease gun with high-temperature lithium-based grease.
Pump grease until fresh grease emerges from the seals (but don’t overfill).
