Today at Atelier Kaz - ex-Honda R&D, F1, Indy/CART engineer

For some reason, it was really slow or even timed out accessing the site Saturday morning but glad it’s back to normal now.




Before removing the left drive shaft, must drain the trans oil.
As always, checking the MTF strainer.

As I replaced the MTF on this NSX in the past, no issues in removing the
MTF strainer cover.
There was not even a metal powder inside the meshed filter so very healthy.




The owner bought the aftermarket left side drive shaft for the MT model.
This is the first time installing the one from this manufacture (Surtrack) for me
but I knew it is popular among other car models owners.






When I first looked at it, it felt as if the amount of air inside the boot
was not adjusted properly.
However, the inboard joint case was much longer than the OEM one so
when it was set at the specified length, it was fine.

Before the installation, I inspected it for a while and although I won’t be
able to tell exactly what kind of bearing was used inside there,
I can feel it’s not like the OEM one using the roller bearing with
tripod/spider design. It felt more like multiple ball bearings but won’t be
able to tell the exact style unless I open it.

Should be fine for street usage as it claims that it has been
reverse manufactured from the OEM one and also each parts no. models
were tested until it breaks down.






As I have never used this aftermarket drive shaft in the past,
to be on the safe side, replaced the trans seal even there was
no MTF leakage.




Left side wheel speed sensor head and the state of the hub bearing.




Surtrack drive shaft installed.
No leakage from the trans seal.




Pour fresh MTF 3 and let the excess to drain out.
