Well, an interesting development: I got in contact with the dealer, Renault have got back to them claiming that the "number 1 hole" (i.e. the one with the wear) is deliberately made larger "for ease of assembly on the production line" . Renault claim to have measured a new subframe -> however...

:) Glad to see you got a positive result and fixed the suspension noise Gavin. Has the handling improved as well- all the Aussies who have fixed it have said it has? PPTom, the hole is enlarged through wear. Even looking at your pics the edge of the hole isn't neatly formed like it would be if...

Thanks for the pics GavinJ. I've been away all week with no internet access and also haven't had a chance to chase up the dealer for a progress report. For repairs a number of people on Oz Renault Sport have had the 12mm high tensile washers welded in place and reported a big improvement.

Any pics?

Thanks Skini. I got mine back yesterday, they actually removed the lower arm/ wishbone completely and measured it and took more photos. I was told the holes were enlarged by 3mm (so a 15mm hole with a 12mm bolt moving around in it.) That's 15000km on a 182 Cup - I think the 182's might be...

It could be Russ- particularly the knock. Butler 205 - all the Aussie ones only seem to have the rear most hole enlarged/ elongated. You might have noticed the front most hole has a metal support / stay that's bolted to the body- I wonder if that is to prevent the same thing happening at the...

Thanks for checking and posting what you found. :) So the inner metal tube that the bolt goes through has thicker sidewalls or something, does it? I think most of the holes have been "out of round" that I've seen- it's just very hard to view the hole shape without totally removing the bolt.

Yeah, I know its a bit of a concern using "home remedies" to fix this sort of fault. However, when you look at your own car you'll realise just how flimsy that section of metal is from the factory- most washers would be "heavy duty" in comparison for thickness.

OK, no worries. Another Aussie owner has posted on OzRS their 172 was affected and has been fixed by welding washers in place. No before or after pics though.

Any updates from the people who were going to have a look? I spoke to my local dealer yesterday and they've had another RSC booked in for the same problem and he's heard from Renault Australia that other people interstate have also reported sub frame wear to dealers. :) Mine is back in again...

:) Thanks. If you can take some pics and post them up that would be fantastic. Mines going back into Renault soon for the measurements of the worn areas to be taken for Renault Australia's investigation. They'll no doubt be contacting Renault France about the issue (if they haven't already) -...

Another 182 Cup has been inspected on OzRS forums http://www.ozrenaultsport.com/forum/viewtopic.php?p=160132#160132 It's covered 32000km / 20000 miles and has wear like the others. Pics are in the above thread. Evidence is mounting that all Phase II RSC's are affected to some degree.

That would be fantastic if you can take pics. I think a lot of Aussies are simply burying their heads in the sand and ignoring the problem. It's making it hard for me to make Renault Australia take notice. I have forwarded on all the pics I've taken to my local dealer and asked them to...

Thanks for the replies- it's been hard to get people to take notice of this "issue". Unless other people start making noise about it to Renault they won't take any action - ultimately a recall and some sort of properly engineered fix would be the "perfect" outcome. To check for this you'll...

Well, I guess it would be good to show what it should look like for comparison, but the bottom line is the hole should be a close tolerance fit around the bolt shaft. Any movement in this joint will result in toe changes every time you accelerate, brake or hit a bump. Renault Australia are...

I helped check out two more RSC's this weekend. The first had done around 40000km (IIRC?), pics are below. The owner said they're a fairly sedate driver and wasn't expecting wear: LHS RHS This one was different from the others I've checked as the RHS bolt was loose so could easily...

Hi, mine actually hasn't been fixed yet. I'm currently being a "guinea pig" and going through Renault Australia as a warranty claim- they are investigating the issue but I've been told they've never seen or heard of it before. Just on the OzRS forum there are a number of vehicles that have...

Thanks Fred. No the bolts aren't coming loose- they've actually got Nyloc nuts fitted. Mine and the one I checked last night were both tight and required a decent length socket drive to undo. It's only the rear most hole on the rear mount that is suffering from the wear- which I figure is...

OK. I helped another person who owns a 172 inspect his subframe tonight- this example has done under 50000km. Right hand side: Left hand side: The wear is clearly evident again. You guys might need to take a closer look- I find it hard to believe only Aussie cars are affected? :S

:S Then I'm confused by how many Aussie cars seem to have varying amounts of wear in those areas. Unless it's to do with our rough roads or something? I'm in my late thirties and realistically drive it very sedately compared to some other RSC owners I know. I've never turned off the traction...

Here are pics of mine (this is a 15000km vehicle, never track raced) : LHS A shot trying to show the hole elongation RHS

A bigger bolt won't work because it has to fit through the lower arm bush. Some Aussie guys have had metal welded on to repair the hole by a mechanic in Sydney, but I haven't seen any pics of what he does exactly. The one I posted above has been fixed by welding a M12 high tensile washer in...

That's the stock M12 bolt in the hole. It's not my RSC, but a guy off OzRS who races his 172 in Production Car racing- so this is hopefully a "worst case" scenario. It happens on both sides and the damage isn't apparent until you actually loosen off the rear most bolt on each side and slide it...

Has anyone found wear in the subframe mounts where the lower suspension arm (wishbone) bolts through the frame? It seems there is a common problem with the rear most hole wearing and elongating. See the pic below - the hole should be a tight fit around the bolt. Obviously this will affect...

I know some owners have had high tensile 12mm washers welded in place over the affected area. A new subframe would be ideal, but if they haven't improved the design then it won't take long for the same thing to happen.

Have you checked the sub frame mounting holes that the lower arm bolts through? The rear most bolt hole has a tendancy to become elongated/ enlarged- even on low mileage Clios.

Good point, hopefully you're right.

Last time I checked Koni didn't make any to suit a 182 Cup (which has the different uprated hubs) with the different bolt spacing. I'd be happy to proved wrong though.... (I just checked again and there's still nothing listed for a Cup.)

Australia is metric. ;)

Did you get onto read that thread? Every person who has had their 1*2's checked has found enlarged/ elongated holes; the guys who have had it repaired have remarked how much tighter the handling is afterwards.
