So I bought the kawasaki nuts and had my mechanic do the job. I even showed him the video and this forum thread. Long story short, I still have the ticking noise and my mechanic and I have no idea what it is. It just sucks that I went through all this (getting parts, taking time of out of my day to get it to the shop, paying for labor) just to find out I didn't solve the issue. My mechanic told me to leave this car with him next week so he can troubleshoot and hopefully get to the bottom of it. It's just so damn annoying because my car sounds like it's breaking in first gear.

Ticking noise? Like a constant ticking? That doesn't sound like rear axle click. The rear axle issue discussed in this thread should present itself as a single click or clunk when the momentum of the car changes between forward and reverse.

Find the thickest marine grease you can, no nuts needed.

No, not constant. Only in 1st gear moving slowly, reversing, accelerating, coming to a stop, turning slowly, going over bumps - mainly when the car receives torque at low speeds. It is definitely coming from the rear, mainly the left axle area. It can be one click or multiple consecutive clicks. It's very random. Any idea, anyone? If the nut mod didn't do the trick, I'm thinking it's the entire CV axle or, at a minimum, the joint??

Z Brothers and Sisters,

Just wanted to confirm this older thread is still very valid. This replacement method still works great, I just did this for my '14 Nismo Z. The renewed silence is a great thing. The quoted parts list is correct.

The following parts list for this fix is correct, see below:

Part Numbers
Nissan spring washer 40037-1CA0A (Qty=6) Cost: $4.74 ea
Nissan cotter pins 00921-5402A (Qty=2) Cost: $1.92 ea
Pro-Bolt M24x1.50 Stainless Steel Axle Nut M24x(1.50mm) Rear Wheel (LSSNUT24150001Z2)(Qty=2) Cost $25.50 - $27.90 ea.

Total parts cost is about $85.00 to fix this yourself. The choices are to add grease or not. This only takes 20-30 minutes max to do yourself. Just have the 32mm socket and a torque wrench.

OK, just did this mod as I had some clunking sound when shifting into 2nd, probably just how I shift, not the transmission. Back on topic after doing this mod, no noise! Very easy to do. Hopefully, it will hold up, I could probably stand to take apart the rear axles and grease them properly, but a little limited on time at the moment.

One point of clarification for those doing this mod. It will require 3 washers per side, so don't throw away your old ones. The stealership was damn expensive here... $60 for (4) washers and (4) cotter pins.

Hi Guys,
My 2017 with 40000km has started making this click noise. Is this "Kawasaki nut" still the fix you guys do to remedy the noise issue?
I see some comments that the noise still comes back even with this method.

Yes. A castellated nut is the solution for the axle 'clunk' that occurs when changing directions in the vehicle at very low speeds.

Hello,370z with what force do we tighten the center rear nut (Nm)
in manual *Auto data* gives little power!

I think most people take it to 80Ft.Lb


From FSM:

• When installing drive shaft, change the drive shaft and wheel hub
and bearing assembly matching marks put at the removal step by
180 degree.
• Use the following torque range for tightening the wheel hub lock
nut.

: 100 – 105 N·m (10 – 11 kg-m, 74 – 77 ft-lb)
