What is a conversion U-Joint?

Conversion U-Joints are used when you need different caps on each side of the U-Joint. For example, if your tailshaft is 1330 series but your rear end yoke is 1350 series. GJ Drivelines offers conversion U-Joints that have 1350 Series on two caps and 1330 Series.

When measuring a Conversion U-Joint, be sure to measure across the U-Joint in both directions (with the caps on and fully compressed) and measure all 4 cap diameters. Also note which sides our outside clip and which are inside. For more information on how to measure U-Joints give us a call.

Worn gearbox or transmission yoke?

Where the yoke runs in the extension housing, it may be worn and undersized, causing the shaft to vibrate.
