FIXED: Rear axle click clunk noise

T-Rex57

Thanks @juld0zer for this fix. Just performed this on my Aussie 2011 370z, clicking is gone at the moment, but I'll report back after some kms travelled.

For other Aussies if you're having trouble sourcing parts (My dealer wouldn't sell me any): Got the Kawasaki Castle Nuts from Partzilla.com for $AU20 delivered

I required two additional spring washers per side (for a total of 6, 2 new and the origina 1 OEM). Part number is #400371CA0A for the spring washers, bought at $3.80 each from Amayama. Bit pricey, but couldn't find many sources.

The new cotter pins part number is #400730L700, I bought 4 of them at $1.72 each also from Amayama (Just as well cos the first pin I bent improperly). Total delivered for the washers and cotter pins was AU$31.08

Other notes: Easy to install even for a ham fisted oaf like myself - I had to tighten to spec, then use a breaker bar to tighten the Kawasaki nut a little bit over to allow the cotter pin to sit correctly
