Two questions techs often ask about drive shafts: do the U-joints need greasing, and does orientation matter? Every TrakMotive drive shaft comes with sealed-for-life U-joints, with no grease fittings and no maintenance, backed by a limited lifetime warranty. Orientation does matter: the U-joints must stay properly aligned, or phased, when the drive shaft is reassembled. If the phasing is off, it can cause vibration and driveline issues.

Key Takeaways

• TrakMotive U-joints are sealed for life: no grease fittings and no maintenance
• Backed by a limited lifetime warranty; if something goes wrong, replace the shaft
• Keep the U-joints properly phased when reassembling the drive shaft
• Incorrect phasing can cause vibration and driveline issues
