Driveshaft difficulties.

Recommended Posts

I've got my V8 in my Z and the driveshaft yoke did not fit into the 700R auto transmission.(Obviously) I figure I need to get my driveshaft cut and balanced but I'm not sure if I'm gonna need a new yoke, a new tailhousing for the transmission. Thoughts?

Assuming you need the driveshaft shortened and not lengthened, you just need a new slip yoke that fits the 700r4, and a matching tube yoke, and to have it mated to your driveshaft, cut to the proper length and balanced.  If you are planning on keeping the flange and u-joint at the rear of the shaft, a 1310 series u-joint will be plenty strong.  Here's an example:

Obviously if you need to lengthen the driveshaft you are pretty much starting over.  The 1310 series u-joints (non greasable) at both ends should still be plenty strong, unless you are making a LOT of torque on slicks...

For the same amount of effort, you could buy a Chevy, Camaro etc driveshaft at a wrecker and have it shortened and balanced with new U joints. The only other component required would be the flange adapter. The flange adapter P/N is available in several HybridZ posts.  JTR may still sell the adapter.

 

Note:

 

  • Measure driveshaft carefully

 

  • Use a reliable driveshaft shop

 

  • Pay attention to driveshaft phasing/angles
