My U-joints are replaceable. They look similar in design to the photos at the beginning of this thread. They have the very same type of semi-circular clip holding them in, but the U-joint itself looks to be smaller.
I took some pictures.
Here is the replacement I received partially installed. I am holding the old one next to it to show the difference in size. The old one and new one have the same size of outer roller diameter, but the over-all width of the U-joint is smaller on the old one.
Here is the Newer one in the Yoke. It sort of fits, but when it's in the middle of the yoke, I won't be able to get the clips on.
And so I'm wondering if I can just weld the ends of the roller caps a little bit to keep the U-joint in place?
Here is a picture. I would weld just a little bit on the outside of the roller and the yoke next to where my thumb is:
Welding scares me for two reasons, I might not get the U-joint centered as well as the clips would, which might make it vibrate. Also, I am worried the weld would damage the roller. I am not worried about replacing it in the future. I don't plan to put THAT many more miles on the car. (knock on wood).
Obviously, the best solution would be to get the correct U-joint, but I have not been able to find a part number anywhere for it.
Any recommendations? There are some other parts shops I can try, but I reckon they will have the same incorrect on listed.
