1. Journal cross engineered with a cold-formed body to ensure better wear and overall strength
2. The red Spicer Life Series ultra-premium grease is replaced with upgraded green synthetic grease, which significantly improved minimum and maximum temperature capabilities and increases bearing life
3. Bearing cups are heat-treated for strength and precision-ground and case-hardened for durability
4. Multi-lip seal with enhanced seal and seal guard material keeps grease in and contaminants out, offering maximum retention in a wider range of environment
5. Thrust washer eliminates friction and end galling, as well as metal-to-metal contact

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.
