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

      This is a story of my life things, I learned eventually (thanks to someone calling me out) that my enthusiasm for discussing and sharing ideas that it came across as arrogance and I'm like... WTF?!    One thing I'm pretty sure I justifiably pride myself on is knowing that everyone will have things they can teach you, and you're always going to find out that something you think you know turns out wrong - you just don't know what it is until you get there.   Just the bursting enthusiasm that comes with ADHD when you hit something that gives you dopamine dumps can come across like you think everyone else is wrong or don't matter. But yeah, I'm a software engineer by trade and also do tuning in weekends and 100% have long had a reputation for  quickly making connections when resolving problems or forming solutions that I've sometimes had to take people form a long walk from start to end to explain how I ended up where I did when it's seemed "too simple" when I've stated my initial case, and had the "WTF" type reaction when they've realised how much was actually considered haha.   My reward is that I get all the curly problems thrown at me.

      Wives never seem to find things funny. Especially when they're trying to sleep, and you've found the new funniest thing ever. I've never seen someone be able to get try and be cranky with me, while they're holding back fits of laughter... 😛   Also, I tell mine it's payback anyway. She has BiPolar. So the household can get quite emotionally wild at times 😛

      I'm not up to date on the latest, but for basic modifications like pod filter, lower springs etc you can get a modification permit at the time of inspection.  For more serious modifications you will need engineering.  Intercoolers used to fall into the mod permit rule but its been a long while since i looked it up.   Either way you will be able to get it registered, just a case of $300 vs $3k .

      Hi everyone! I’m the new owner of a 1996 R33 GTS-T, I’ve purchased this car over from Queensland and brought it to Western Australia and I’ve found that there is a hole cut out in the engine bay for the FMIC that enters into the wheel well (fender liners are in the boot). For anyone that has had to get their car over the PITS here, will this be a major issue?
