Noise Coming From Rear Wheel Area.

R33 GTST S1

It's a clear crisp CLICK. Not a thud, or bang, or grinding.

It sounds like it's coming from the rear driver's side wheel. But then i've only heard it when driving, so it's hard to say.

It will happen (sometimes) when coasting in neutral at low speeds, and then selecting 2nd.

Or when blipping the throttle at very low speeds. So basically when it's throttle off/on/off suddenly, but only on light throttle, and only sometimes.

Like a small shock to the drivetrain. I was thinking diff or uni, but would they make a sharp click?

The noise has been there for a long long time. I've changed suspension and clutch during this period. So theyre ruled out.

Maybe someone has had this CLICK before and can narrow it down to a couple of high probabilty areas to check.

Cheers

At those low speeds (say in 2nd), does the click become prominent as you switch from accel > decel > accel > decel??

The diff can make that noise. May need to change or simply top up diff oil.

Nissan mailed me 'under recall' to bring in my former R31 Silhouette with LSD to change the diff oil & the clicking stopped.

hmm good question. i'm pretty sure it's never happened more than once at a time. maybe i havent tried. but no, it doesnt become more prominent. although decel>accel at low speeds will cause it. just not always.

if it's just diff oil, that would be a good outcome

Oh well, if it's just the diff oil, it might be due diligence to make sure the viscosity is correct. It may need to be thicker.

But hey I could be wrong.

I have the same issue, and have had since I got the car.

Last service I asked for a diff oil change... car still makes the noise though.

I'll be changing it myself sometime soon(ish) when I get a chance, just to be sure that it's been changed then.

[Munkyb0y]

the click i get isnt constant. its a one off every so often. thats why i'm thinking diff oil probably isnt the issue.

i will most likely change it anyway, for general well being.

if i find the issue, i'll definitely post it up here.

the diff oil could still be the issue as the angle of the ground you are on at the time may be affecting what the oil is covering. it isn't hard to change the diff oil. i'm sure even someone with girly hair like you could manage it, LOL

oh btw, last night i was driving around trying to get it to click, with no luck. eventually it happened a couple of times in 1st. weird.

anyways, diff oil, and then go from there.

Check rear suspension bushes, exhaust mounts + bolt tightness in general.. worst case scenario - excessive backlash (space between gear teeth before they make contact) between the crown wheel and the pinion inside your diff, can be adjusted with careful precision if you can safely raise the rear of the vehicle and drive it, a mate can use a mechanics stethoscope (or a metal bar/screwdriver ) and place it on the diff housing (don't inhale exhaust fumes or get caught in spinning wheels!) to listen for excessive grinding, knocking etc (very thorough way to check how your diff is going)

check the wear in the outer joint of the half shaft, so pull the half shaft out (CV) and knock the outer off, clean it, regrease it and clamp the boot back on, could be wear there.. sounds to me like a worn outer.
