: Opening Up Toyota CV Dshaft

Merry Xmas and all to everyone. Just got my cut down toy d-shaft back yesterday and I think the CV won't have enough movement.

It looks like I can just turn down the ring that surrounds the centering mechanism to increase the movement, anybody tried this out?

What year cv you running, are you talking about operating angles?

Yup I'm talking operating angles. Jeez I'm on the east coast and it's barely reasonable to be awake!

I believe it is a 1984 shaft but could be wrong not having a lot a toy stuff floating around. It almost mates to a large (post 88.5) zuk flange, just need the zuk flange opened up by 15 thou or so. The flange bolt pattern and size match as well.

Right now it only seems to have about 15-20 degrees of maximum angle. The u-joint end has much more but doesn't matter since it won't be running with any angle.

My stock shaft is almost bottoming the yoke (sj-410 flange to mate to sj-tcase) when drooping and the max angle is probably 25-35 degrees or so (been a while so don't quote me on that)

hey ken, when using a cv joint on a shaft you should point the 3rd. member flang right at the t-case, are you putting your 3 link rear susp. in at the same time? or keeping your leaf springs for a wile?........

Does it bind at full droop?

We have a max of 18 deg from centerline on the toyota CV, a stock sam shaft has 28 deg.

I am using a sam/sj-410 flange shaft at about 22 degrees. It's barely got enough movement.

I won't be putting the link suspension on the front yet, only the rear will be done before break is over. Have to make some engine and bearing repairs instead.

Looking into the "window" at the centering mechanism there is a steel ring that looks to be protecting/sealing the centering junk. It is part of the flange and looks as if it could be turned down about 1/8" and get about 10 deg more out of the shaft. I need to pull the flange end of it apart to see for sure.
