Need help getting a u-joint for my steering
This is my pump. It has a flat spot and the spline count is 30 with two half splines on either side of the flat area. Its 3/4". I orderd a 3/4 DD X 3/4 - 30. But it's too small.

Re: Need help getting a u-joint for my steering
It is probably 3/4 with 36 spline - check my reply in this thread out.

Re: Need help getting a u-joint for my steering
So my pump is not abnormal with the flat spot? Who to call to get someone who knows these parts to help me? Thanks.

Re: Need help getting a u-joint for my steering
When you count the splines you need to include the flat spot. I used Borgeson http://www.borgeson.com/
It's been several years so I can't remember but I think YJ is correct 36 spline. After 72 pretty sure GM changed the gearbox...might be 74 again I can't remember

Re: Need help getting a u-joint for my steering
The spline size on the steering box is 13/16 36 spline or at least mine was. Here is a link to a chart with sizes http://www.flamingriver.com/p_view_i..._Tech_Tips.gif
