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.
Can I make my tailshaft stronger?
Yes. There are a few ways to make a tailshaft stronger.
- Increase tubing diameter. Larger tube OD means a stronger tailshaft.
- Increase tubing wall thickness.
- Increase U-Joint size.
- Switch from greasable to non-greasable U-Joints.
Tube bent?
Visually check the tailshaft is running straight in the vehicle.
