juld0zer, thank you for presenting this solution. It worked out fine for me with only minor changes. In the future, I would probably get 4 new washers for each side to be safe. They're actually kind of expensive for washers, but they're still only a couple bucks each.

Also, I should clarify that my clicking was caused by a lack of moly grease on the axle. My adjusting cap was quite tight and not the cause. For me the Kawasaki nut was just a preventative measure to keep it from happening in the future.

for the record, you can probably use flat fender washers and just buy 2 new spring washers (one for each side, to go on after you stack some fender washers). since i believe the way the spring washer works is that it provides tension against the nut to keep the nut from getting loose. stacking 3 spring washers on top probably keeps this from happening.

problem is finding a fender washer with an inside diameter big enough to fit over the axle, and outside diameter small enough to fit into the hole for the hub though. i'm taking apart mine tonight to see if i can find fender washers at grainger that will fit before i order 2 more spring washers. not like the car is going anywhere anyway...its been raining for a week or two now :(

If you are able to take the spring washer to Grainger, I guarantee they can find you something that will work. And I agree, it is probably appropriate to only use one spring washer per side.

just an update... i picked up 4 of these and they work perfectly

Why 4?

it goes, 2 washers, OEM spring washer, kawasaki castellated nut on each side. i did not feel comfortable using 3 OEM spring washers in order to get the new nut to fit correctly

Oh gotcha!

Thank you for the link :tiphat:

I am currently using 3 OEM spring washers. Kevin at the Z clinic didn't seem overly concerned about it, so I wasn't either. But I will probably go ahead and order these anyway; they're not expensive.

they have local locations all over the place, so it was a no brainer for me :)

I too had the click on my 2012 Sport with 27k on the odo. Took it to Nissan at 0700 this morning and just picked it up. They removed the rear axles, gave everything a good lube and now no more click :) Super quiet and sounds the way it should. They said there is a TSB but the TSB number isn't on the work order.

Did they at lease give you the TSB case number? If you don't mind please attach the dealership's invoice so at least us forum members can show it to the dealership. Thanks!

I had mine done a couple of years ago and the rat bastages charged me $160.

Those of you that did it themselves, did you unbolt the axle from the diff and smear grease between the diff and that shiney part of the axle? How much grease did yo put on there?

I can call them tomorrow to see if they can provide me the 370z specific TSB number. I know there is one for the 350z, so I'm not sure if they are just using that or not. Took them all morning and it was ready for pickup at noon.

OUCH!!!!! I am sorry to hear that. When I drove up, the Service Advisor asked why I was there and after i told him, he said yea I heard it when you drove up. :happydance:

My Dealership just emailed me back and said and I quote.....

"TSB # for the correction we did to your vehicle is NTB12-055E"
