Swapping driveshaft yoke
I need to put the NA auto front (trans side) yoke on my NA Manual driveshaft. Any tips on doing this or could I bring both of them to a driveline shop and have them do it with no problems?
|
Isn't the actual drive shaft a different length?
|
If I read the correct specs, the TII shaft is a larger diameter and 966mm long while the manual NA is 967mm long
|
Wait, which is it? T2 or auto?
From my understanding: T2 shaft is thicker with a bigger flange/plate at the rear, and Auto shafts are the same as NA manuals except shorter. Also, I think it is possible to change the front between different ones, but it sounds like you need to be handy with welding/grinding [from reading the thread on changing the U-joints] |
It would help is we knew what you were trying to accomplish. If you're trying to mate a TII tranny to a NA rear end, Then just use a driveshaft for an automatic RX7. Sounds like you already know the yoke is the same for an automatic transmission and a TII transmission.
Auto driveshaft is a smidge short, but servicable. The best is to simply buy one made by Mazdatrix that eliminates the "smidge". |
yup, tii trans to na rear. And it's not just a smidge, its 53mm shorter and has killer driveline vibration/chatter.
And Derek, the auto has a TII front spline with the NA rear flange, just is too short. I might just get my auto extended... |

That 2 inch / 53mm difference is a lot, and I wouldn't suggest the auto shaft to anyone.
In my case, I just went with the Mazdatrix driveshaft, but I know others have had them custom made. You'll probably have to shop around to find a place a) willing to do it & b) do it for a reasonable rate. https://www.rx7club.com/attachment.p...1&d=1307983865 |
Yeah, ive been using the auto shaft and I'm scared, but now I finally have the money n such to start getting proper parts. Really didn't want to spend $300 on a piece of pipe with some joints on it haha.
Has anyone got an auto shaft extended the 2"? |
