How to Measure a Slip Yoke
Measure OE slip yoke with a precision tool to determine which Sonnax yoke you need. Length, journal size and U-joint series are critical dimensions requiring accurate measurements.
- Some slip yokes have missing splines — include the missing spline in your count or count the splines on the transmission output shaft.
- Also check if the OE yoke has a counterbore and whether the transmission tail housing uses a bushing or roller bearing.
