22 spline output shaft

[acn]

Today I found a 22 spline t-case with matching output shaft from a 1990 Galant GSX in the local pick n pull. Somebody had actually greased the output shaft so the splines weren't worn out even though the car had 170k! My 23 spline setup is completely worn out. If I have both the 22 spline t-case and output shaft, can I replace my 23 spline setup with no issues? I thought I had read that it was possible to do this, but I haven't found anything to verify. Are 1990 GSX t-case gear ratios the same as the VR4?

Yup they are the same. It's just a matter of draining the trans fluid, taking off the end case, removing the VC (watch out for the ball bearing) and sliding the output shaft out.

Tell me more about this ball bearing. I already removed the shaft from the wrecking yard galant and didn't see a ball bearing. Gear ratios are the same in the 90 t-case?

Quoting CutlassJim:
Yup they are the same.



The ball bearing is what holds the output shaft from sliding out. When you pop the VC off there will be a hole in the shaft from the trans. If it's upside down it will fall right out. If it's right side up use a magnet to get it out. The shaft won't slide out if the ball is still in there.

Thanks for the info! When I removed the junk yard shaft, it must have been upside down and fell out because I didn't notice it.
