The universal joint is a key pivot that allows the driveshaft to transmit torque between the gearbox and the axles at a variable angle. If you hear metallic clunks, "ringing" (especially when starting off), feel strong vibrations transmitted through the machine, or see rust dust around the joint, these are classic symptoms of a worn U-joint. Ignoring the problem leads to damage to the driveshaft yokes and, in extreme cases, to a complete driveshaft failure.

A new, tight-fitting U-joint restores the smooth operation of the drivetrain, eliminating vibrations and clunks.
Vibration-free operation protects the seals and bearings in the gearbox and drive axles from premature wear.
A functional U-joint ensures lossless power transfer, which translates to the full performance of the machine.
Before installing a new U-joint, carefully check if the seats in the driveshaft yokes are not worn out or oval. Installing a new U-joint into worn yokes will lead to its immediate destruction.
After installation, generously grease the U-joint through the nipple. Regular lubrication according to service intervals is crucial for its lifespan.
Answer: It is highly not recommended. U-joints on the same shaft wear out at a similar rate. Replacing all U-joints on a single shaft at the same time is the best service practice and prevents the return of vibrations.
Question: Does the driveshaft need to be balanced after replacing the U-joints?Answer: For construction machinery, which operates at lower rotational speeds, balancing the driveshaft after U-joint replacement is usually not necessary, as long as all components are installed correctly.
