hi im new the site so please bare with me as i cant find any info on the topic yet. i got a 97 rs4 stagea and when i do a slow u turn the front of the car clunks and shudders in sync with one rotation of the tyre. im new to mechanics and dont know where to start. the clunk is worse in 4wd or when reversing. it shakes the whole car a bit and can be felt through the steering wheel. while driving straight or doing a standard corner its fine and is quiet as a mouse.

Welcome Patrick,

Probably best to have someone look at it if you are not used to playing down below, could be a few things, CV, tie rods etc. Maybe go for one of those free 'safety checks', then get back to us with results.

I agree safety check is the way to go, but don't let them do the work unless your cashed up :(

Hi and welcome

If it is a heavy metal clunk and only there when on full lock I would put money on it being a CV joint. If you are not any good with spanners and things mechanical then it might be best left up to a mechanic to replace.

Mine used to do that too.

But only if I was in 50:50 mode. And only when I turned sharply slowly.

I dunno why but for some reason I thought it was normal.

Maybe someone told me it was. It was a few years ago so I cant really remember.

How often are you you using your 4wd lock button ? unless you have some serious slip situations, such as its snowing there or you live on the side of a grass mountain, not wise to use it. It will quickly destroy itself on hard surfaces.

sorry i havnt been able to reply in a while cos i was outta town. i might put it in for a safety check ike yous suggested. the tie rods/ends should be fine as i replaced them about six months ago. the problem was still there before and after. i also had the cvs cleaned up about the same time, apparently the boots were split but the cvs were fine so he cleaned them out and put some new boots on them. ive also checked tyre pressure and its fine. i also recently replaced the front stabilzer bar linkages which were worn. as for the 4wd use i rarely use it. maybe for 5 min or so every 2 months just so it gets some use. ill book it in for a safety check and let you guys know. thanks

are your tyres all good? Also, might be a good idea to have the Attessa fluid changed (you'll find the reservoir in the rhs hatch in the boot).

To change the attessa fluid can you just suck all the old stuff out of the boot compartment with an syringe. fill it to top turn car on and crack the bleed nipple under the car and then keep filling it?

i did the safety check and was told that the cvs were fine and so was the tie rods. he seems to think the rear difff locks and causes the clunk. as burkey said his used to do it so is this a standard thing or are we just special. i might change the attessa fluid to as most of the mechanics would probably miss it. i asked one and he couldnt tell me what the oil was for.

i have tracked down the cause of the problem. the fluid in the transfer case was badly burnt and past its prime. the fluid in the rear near the hatch only activates the awd and it was fine. the oil i changed was in the centre diff off the side of the transmission. i used castrol transmax z and the shudder is all but gone. reading the manual a little bit of a braking effect is normal but the amount i had was pretty severe. thanks for your help guys

      Reading your posts Josh, sometimes I feel like I've gone in a time machine back to the 90's when everyone was doe-eyed and figuring things out for the first time.  I've lost track of how many single turbo GTR's I've seen on track that haven't burnt down lol. Everything has been figured out a long time ago. These things are at the point now where its essentially turn-key to go single turbo.

      Among other things yes. Making sure to either use an oil pressure regulator or the right restrictor size for your oil pump/range of oil viscosities you intend to run, making sure you plumb the lines correctly, turbo should be placed such that it siphons properly even when the water pump isn't turning so you don't boil coolant in the turbo after shutdown, oil return should be low resistance and also preferably picking the one that is most likely to return to the pickup as opposed to some other irrelevant part of the pan. It's far from impossible to figure this out but I have seen people really, really struggle and if that's the case it's easier to just take the path of least resistance. To me, bolt-on twin turbos are a fixed cost whereas single turbo is almost unbounded.

      Latest round of updates on the car. I purchased and installed a SWS clutch slipper to help with 60ft times and got some second-hand good condition 275/40R17 Hoosier DR2 radials. Test and tune in November showed the tyres were an upgrade over my over 15 year old mickey Thompson's and I got a 1.8 second 60ft and pb et of 11.71 but even then, that run wasn't great due to rain and driver error (the event got called off 10 minutes later fast forward to the weekend just gone 25th of Jan and there was finally a break in the weather to let racing happen. The first run the track was slippery and only managed a 12.1@129 Second run the track was better and got a new pb et and mph: 11.54@131   Lith and I then worked out that I installed the previously mentioned clutch slipper incorrectly and its never been working, and I had just been dumping the clutch the entire time, we also noticed it was on street boost and not race boost. So I lined up for a third run with the car turned up in the first two gears, but the passengers side axle objected to clutch dumps and left the chat which stopped my weekend.   so there will be another attempt in the future once I replace the tyres as they rubbed and are stuffed now. but a low 11 should be on the cards.

      Turbos don't require pulling the motor apart so that's "easier". I would recommend the Nismo R3 turbos instead if you want to do stock twin turbo. It doesn't make as much power as the 2530s but it's only like ~50 whp off the mark and should have better response (ball bearing CHRA, slightly smaller turbo). A local that went with a Garrett G30 and 6boost manifold recently nearly burned his car to the ground after the hood insulator started melting and and burning so if you go single turbo I recommend doing a lot of research and validation work to make sure you don't do the same.
