NSX Health Check Service

5. Driveshaft – Right side
This is one of the weakest points on our NSX.
Almost all of the NSX will suffer from leaking joints on the driveshaft especially at the right side.

This one was the same and already making noticeable ‘click’ when the wheel was turned by hand.


For most of the NSX, the joint can be separated from the hub/spline with reasonable amount of force. However, on this one, it looked as if it was never removed and heavily corroded that it just didn’t want to come out.

In the end, I had to use the hydraulic hub puller with one big tap to crack open the corrosion. The inner joint was leaking and the outer one was making the ‘click’.

In order to speed up the process, I normally prepare the refurbished one ready for the replacement. During the refurbishment, each joint will be inspected in detail. Then, each roller will be disassembled, cleaned, then lots and lots of pin bearings are packed with new grease to reassemble the roller. With this process, it will provide you with completely different feeling when the joints were turned by hand.

The joints and the shaft were painted in black and using the new boots and grease, the length was set to the spec to adjust the amount of air inside the boot to complete the refurbishment.

Beautiful driveshaft in place.
