Full Description
The 1203-18 transmission yoke is the connection between the gearbox tailshaft and the front of the driveshaft. It splines onto the transmission output shaft and carries the front u-joint of the driveshaft. For 1251 series applications, the spline count and hub diameter are the two specs that determine whether this part fits your tailshaft correctly.
1203-18 Transmission Yoke — 1251 Series Specs & Tailshaft Fit
The 1203-18 transmission yoke specs: 18 X 0.800 spline | 1.178" hub | 4.875" CJ-to-end. Compatible with: NISSAN- SUBARU. Hub diameter determines engagement depth on the tailshaft — if the hub is too short, the splines don't fully engage. CJ-to-end affects driveshaft working length.
After a transmission rebuild or swap, confirm the tailshaft spline count hasn't changed before installing the 1203-18 transmission yoke. Not all 1251 series transmissions use the same output spline across all years and configurations. Count the splines on the actual shaft.
