Frequently Asked Questions
Q1: What vehicles are compatible with this splined cross spider U joint kit?
A: This kit is designed for heavy-duty commercial vehicles such as Class 6-8 trucks, trailers, buses, and off-road equipment. It fits many OEM spline profiles (14t, 16t, 18t, etc.). Please provide your vehicle model or spline count for exact match.
Q2: Is the kit pre-greased or do I need to lubricate before installation?
A: Yes, each kit is pre-lubricated with high-temperature grease. However, we recommend applying additional grease during installation using the included grease fitting.
Q3: What is the average service life of this U joint under normal conditions?
