Hi I got 2 new tyres on my car today and as I was leaving the tyre shop I gave it a boot full in first (not trying to spin the wheels) then grabbed 2nd, all good, then once I backed off to a roll there is a loud rattelingish type of noise coming fron the mid section of the car.

I took the fuse out and the noise dissapears completely, so im guessing the transfer has thrown a bearing or something. Has anyone come accross this type of noise from the transfer case.

The car has around 500hp ATW, all the tyres are the same rolling circumference which is why I got new tyres on it in the first place.

Any help/advice would be appreciated.

Cheers Christian

Ps I you need any more info please let me know.

I have just dropped the fluid in the transfer and its spotless, the front diff on the other hand had a thick metallic goo on the magnet and also there is about 10mm freeplay in the front yolk when you twist so im now assuming its a failed diff bearing.

So next question can the front diff be completely replaced in the car??

Does it rattle at idle?

A friend of mines R32 rattled a bit at idle. His was making 393AWKW, he liked to launch and it started making noises after a while. I hear its relatively common for the transfer case to get a bit upset.

Ill get in touch with him and ask what he did and whether it can be done in the car.

Yes I had much the same happen. Transient/part time vibration from the drive train. It was a stuffed front diff.

Anyway with a bit of fiddling the front diff can be replaced without too much gear having to be removed. Added bonus is they are cheap too as alot of people want RB26's and have no use for the diff. Just make sure you get it shimmed properly.

Spot on mate, front diff was mince, I drove around 10klm with different tyre sizes, (bigger on the front by 40mm in circumference) and it was facked!

4 hours and it was all changed, I got a whole sump for $150 and now it's great!

    • Not really, no. Anything you would do is easily reversible.
    • I would like more noise related info for my truly uneducated guess  Does it do it at idle or when revving, clutch engaged, and disengaged? Does it only do it when the car is moving? I've heard "similar" noises from a clutch pack that left the chat room, and CV joints that have chewed themselves out But as Matt said, how's the yokes, tailshaft and centre bearing going after their last little issue Fingers crossed it is something simple  Weird noises make me cringe 
    • One other question, is there a chance that changing the idle speed can lead you down a rabbit hole and is the reason the tuner didn't touch it? Reason I ask is because if that's the reason the tuner avoided it then I probably shouldn't be touching it lol.
    • Pfft. As if I'd ever point a high pressure washer at my car.
    • The nature of my commute has changed. Way back then it was traffic lights all the way, for ~28km. It sucked. When they finally stitched the expressway together I could do a good 15+km of it at a steady 80-100 with no stopping. That alone has gotten me down to flat 10s. Prior to that it was mid-high 10s. I can't remember the delta that I saw when I got the idle down. It was only ~150 rpm, because the idle speed was never terrible, but for the delta in consumption to be noticeable it would have had to have been at least 0.2-0.3 L/100km - which is not to be sneezed at when it comes for absolute free. It's only about 50L per year, but that's ~$100. A few extra pizzas is always welcome. Note that I have a record of every tank of fuel that has ever gone through my car except for a handful put in by someone else, like my mechanic. I can show you the difference between stock RB20 and tuned RB20, stock RB5Neo and tuned, winter and summer fuel blends, winter and summer fuel blends when the ambient temperature is not appropriate for the blend, working O2 sensor, blown O2 sensor, boosting f**k out of it and frightened to boost it because it is pinging, and so on. OK, I probably can't do all that now with 100% clarity - but at the time when any of those things were in event, you could see it in the records. There's 25+ years of simple tank after tank records, so you have to look for landmarks to work out approximately how old any single record is. What's really important is the meta data and that lives in my head.
