• Forged high quality alloy steel cross is case hardened to provide good wear resistance and maximum service life. Pre-installed grease fitting in the cross saves time, prevents installation damage and allows for easy U-Joint maintenance.
• Forged high strength steel cups are case hardened for strength and durability. Cup face and outer diameter are precision ground to provide precise fit, lock up and balance ability.
• High carbon steel needle bearings are through hardenend and precision ground using a optimized crowning profile for maximum life and load carrying capacity.
• Seals are made out of high quality nitrile rubber for optimal grease retention and contaminant exclusion. Multi-lip seal is pliable, yet tough and tear resistant.
• All U-Joints are pre-lubricated with a premium, high temperature grease that performs well in a wide temperature range and provides a long service life.

Greasable vs. Non-Greasable

While non-greasable universal joints were once considered an upgrade over greasable universal joints, the differences in strength and durability are negligible today. Advancements in technology mean either option is a great choice, but there are some key pros and cons to consider:

Preventative Maintenance Tips

The key to maximizing the performance and durability of any universal joint - as well as related parts such as drive shafts - is preventative maintenance. Universal joints are designed to last the life of the vehicle, but can wear down or break if neglected or overloaded. Follow these tips to avoid premature failure of your vehicle's drivetrain:

• If a greasable universal joint is installed, periodically check them to ensure they are properly greased (at the very least, at every oil change).
• Inspect the yokes that hold your universal joints for cracks, stress marks, or worn or damaged seal mating surfaces, and replace them if any of these are present.
• Check your seals for signs of leakage, and replace them if leaks are present.
• Periodically check for drive shaft play, which is an indication that a universal joint or seal has failed and needs to be replaced.
• Inspect drive shafts for cracks, stress marks, dents, or bends, and replace them if any of these are present.
