How to Measure a Slip Yoke
Measure OE slip yoke with a precision tool to determine which Sonnax yoke you need. Centerline to end 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.


A Spline Count
B Journal Dia.
C Centerline to End Length
D Barrel Length
E U-Joint Width*
F U-Joint Cap Diameter*

*U-joint bores in yoke will be slightly larger than the actual U-joint dimensions given in the chart below.
