Just to clarify with respect to the installation issues. We're very familiar with Nissan's habit of using different length and shaped stub axles in the various trims of 350Z. With the 370Z, the base model includes traction control but still an open differential. In the process they also elected to use a revised set of stub axles as well. So with 6 different stub axle choices even OS Giken wasn't entirely sure what ones to use. We ordered one short and one long axle in preparation for the installation. Upon inspection of the OEM parts we discovered that we need two SHORT stub axles NON TAPER with snap ring grooves/snap rings. Instead of sending Chris home and ordering a second short stub axle we machined and modified his existing axle to precisely the same measurements and tolerances of the OEM part which including machining a new snap ring groove. This is a substantial amount of extra time, but we didn't charge the customer of any of this and our objective was to complete the job as promised and get him on the road safely. Under normal circumstances no modifications are needed during install. Mission accomplished.

So if I have a base model, I can order 2 short stub shafts from OS Giken and they will fit without modification?

You have to order them from Nissan.

The stub axles are a Nissan oem part. You can order them from Ryan or myself and we will make sure you have what you need. It goes without saying you also need two new side bearings.

Did you replace the side bearings? If so, do you have the part number?
Thanks

Chris is mistaken. We replaced the side bearings as it's not possible to remove them from the old diff without likely damage. We did NOT replace the side seals because they looked perfectly new and had very low miles on them. No reason to change them out.

Guess I had it backwards then.

Thanks guys! Definitely the part I thought it was. I also heard they were pretty tough to get on there.

Also keep in mind with the OS LSD you will need 2 of the Right Side stub axles, NOT 1 L and 1 R. Oh and yes, they can sometimes be a huge pain to get in there

Right. I'm actually putting a Quaife into my base open diff and it shouldn't require any axle stubs.
