Metallic clicking sound from rear of car

Unclemeaty

Pull the rear-driver side wheel off and check the ~1.25 inch axle nut - It takes you about 5 minutes to check this. I had found the axle nut on mine had backed out a full 2 turns and made the metalic clanking that you may be experiencing. I dont think the passenger side has this issue due to rotational direction. Let me know what you find. I had posted some pictures in another thread about this.

And I paid Nissan $370 to do this?

do you know the torque rating for this offhand? I can look through the service manual but too lazy.

my car does not click but something to jot down in my notes.

133 ft/lbs.

I don't have it on my car yet, and the axle hub lock nut is good and tight. I did have the problem on my previous car, the G35 at about the 2 year mark. The dealer performed the axle rotation/lubrication as mentioned in the TSB and it was gone after that.

thanks! i will keep this in my notes and make it habit to check the torque from time to time. i might even be able to reach it without removing my wheel since i dont use center caps on my Weds. (not sure, will see)

i do remember reading about this in the G35 forums as well. luckily my 04 G35C has not had this noise the last 7yrs, but if it ever makes this noise i know wat to do.

Depends on the model.
Models with the adjusting cap (large beer cap looking thing over the axle nut) only requires 100Nm/77ft lb max.

Based on the FSM, only the 2009 and some 2010 models do NOT have the adjusting cap. In those models, torque it up to 133-136 ft lb.

where is this nut located?

It is in the center of the hub behind your rear wheel (access may be possible through the wheel with the center cap removed). It is what holds your wheel hub on, and hence keeps your wheel attached and the axle attached to the hub.

There has only been 1 report of this being loose that I'm aware of so far, but it's a good thing to check if you have the wheel off anyway.
