Tesla SDU - Front and Rear Driveshaft Compatibility?

Post by elShankos »

Hi there,

I am planning on using a Tesla Model S Front SDU in an EV conversion of a Subaru Legacy which will involve putting the F SDU in the back and making the car RWD instead of AWD. The reasons for this (instead of using a rear SDU) are space and orientation of the SDU within the original subframe etc...
Q: For the Front SDUs, can one remove the half shaft arrangement a A) below and use a pair of Tesla Model S rear driveshafts at B) and C)? Could work if the splines are the same right?

Then I could use a pair of basic new aftermarket driveshafts such as these?

I have hunted all over the show for the answer to the above but haven't found anything definitive so apologies for the noob question if it is detailed somewhere where I have missed it!

The same company sells the front drive shaft parts too.
The reason for the extension axle is to limit torque steer.
The more equal the drop angles the better.
