R32 Skyline Clicking Noise In The Rear - Video Link

[ALX32]

My R32 GTS-T is making a clicking noise at the rear end when driving at low speeds (taking off, 2nd/3rd). Can be heard when I start backing the car out at the start and also when I put it in gear to drive back in.

Any feedback/suggestions will be appreciated.

Thanks,

Alex

Have you checked if your driveshaft and tail shaft bolts are tight?

Uni and cv joints not worn?

They would be the basics id be starting with....

[ALX32]

I had a look under there today and everything looked quite solid. I'll have a proper go soon. Could it possibly be my diff or HICAS system? I still haven't put in a lock bar or changed my diff oil since I got the car about 5 months ago. Who knows when it was changed before then lol.

Thanks!

Get it up on a hoist get someone in car and let it run in 1st gear then get ya buddy to let clutch in and out and listen/feel the x-members, arms, etc get ya sexy little fingers on everything you will find it that way, OR as GTRPSI said could be easy uni, c'v bung exhaust rubber!!!

CV's if everything else looks fine. Can also be the Nut that holds the shaft into the hub is a little bit loose. They run a castleated nut and split pin. If you can isolate if it is one wheel or both then you can tighten the noisey one up by one hole. Unless it seems way to tight already

My commy did this when the cv in the drive shaft was worn

[ALX32]

Thanks for the feedback guys, driveshaft + tailshaft bolts are all tight, its pretty clean underneath so i'm guessing It to be the CV's. How would I go about fixing these up?

[ALX32]

Forgot to mention that it also does it more on hills and angled surfaces. Would that lean more to any outcome?

[ALX32]

The bush on the bottom of the anti-roll bar is bent. Could that be a possible reason?

[89CAL]

Did you read what I said about the driveshaft hub nuts? Give that a go

[ALX32]

I took the car to a mechanic today and he tightened 6 cv bolt nuts up however the noise is still there. He also told me there is diff backlash. Still not sure what it is. The car has a heavy duty clutch and lightened flywheel, not sure if that has anything to do with it.

Thanks everyone for the input

[89CAL]

He tightened the 6 bolts from the driveshaft to the diff stub axles, this isnt what I was talking about

Check the 1 large nut in the hub (outer part) of the driveshaft

[GTRPSI]

Yes the large center hub nuts can cause a clicking sound, more noticable when turning a tight corner at lower speeds.

[ALX32]

The centre hub nut is all tight. Had a fiddle with a few things under the car and then went for a test. As soon as I started backing out in reverse.'click,'... Anyone in Brisbane area want to come take a look? lol

wheel bearing?

[89CAL]

Was the nut tight or torqued? If it were me id back it off and re-torque it. If the split pin doesnt line up then go further dont back it off

[ALX32]

You mean the nut behind the centre cap that has the pin it it? What should it line up with? I'm still figuring out how to upload pics on this thread lol. The noise is most predominant when I'm at the end of letting the clutch out. If I let it out with no revs then it does it most loudly.

[89CAL]

Yeah thats what I mean. Has a torque spec. Then you put the pin through. If the pin wont tighten go a bit tighter

If it were me id get a second person to have a listen to see if they can pinpoint the noise.

[Black4DR]

Was the nut loose? If no look somewhere else mate. Something has worn out.

Take it to a garage and ask for an opinion. They shouldn't charge if they think they might get a job out of it.

I think it's either UJs, CV or diff back lash. It could be anything really. I had a Subaru at work that was making a clunk noise on rough ground. Believe it or not it was the brake pads were loose in the caliper and were jumping up and down.

The point I'm trying to make is it could really be anything and unless you have dicked with something tighting all of the bolts in the world isn't going to solve your issue. And if it is a loose bolt thank you lucky stars your drive shaft hasn't dropped Out...

Hey guys,

Don't worry I had it at a workshop and they checked everything visible in the undercarriage of the car so I haven't just been loosening random bolts off. I'll be taking it to tuner soon to get another opinion. Cheers fellas.
