My Jaguar XFR does it as well (As severe as the YouTube Video above) and is RWD.
A Lexus IS250 (2006) that we have within the family does that.It's under Lexus warranty...they checked it and found nothing wrong.
A quick Google search of 'Lexus IS250 full lock' brings back many threads. Lexus say "the front wheels tilt when on full lock and it is the tyre struggling to grip at that angle. nothing to worry about and not dangerous, they all do that"
"
The outside one (ie left front if you have right hand side down) 'skids' about 1/2" outwards and it is that skid that makes the clunk. The tyre is a bit too wide for the angle of lock and weight on it and it slips."
Someone also wrote:
"It's normal with standard tyres however I do not experience it when using winter tyres, that have a softer compond."

Dan. Will PH be picking up the ball with the crabbing issue with Mercedes? As well as the HJ link we have PHers with the issue on various Mercedes.
http://www.pistonheads.com/gassing/topic.asp?h=0&a...
We are in discussion with them currently and awaiting official response. I think it's safe to say there's an 'awareness' at MBUK though and it's useful having that forum link so thanks for that. If there's anyone else with experience of the problem please pitch in as the more information there is the better. For what it's worth the closest I've experienced to it is when I've 'locked' the diff on a DCCD equipped Subaru and tried to make a low speed turn! In the E-Class I could also feel the steering weight up just before it happened, so you'd go from normal light off-centre, suddenly 'stiff' and then the chunter from the front axle. It's not isolated to Mercedes - I can think of several AWD models I've also experienced it in (Porsche Panamera and 911 Turbo, Nissan GT-R, AWD F-Type, etc...) but it's by far the most dramatic in the C43 and E43 we've had in on test. You'd perhaps indulge a 911 Turbo or GT-R with a degree of 'tightness' in the diffs but I find it hard to believe this would be considered optimal in a vehicle like a GLC, C-Class or E-Class, even one with AMG branding. http://www.pistonheads.com/gassing/topic.asp?h=0&a...
Soon as we have something official from them we'll make some noise on the homepage but, suffice to say, there is a conversation taking place.
Cheers,
Dan
At walking pace trying to turn it felt like it was trying to skip accompanied by a chirping noise.
I had 2 EVO VI TME and neither of them had an issue like that.
Thinking about it, it only happened with just the one position on the STi DCCD. I think the handbook may have advised against it. It was 11 years ago and I've lived life like Iggy Pop over the last 11 years and my memory is fairly f
ked on most things such as trying to remember what setting it was on. MartinGLeeds said:

Yep, on DCCD Subarus that only happens in the 'Lock' setting on the diff which is basically the last resort/get me out of that snow drift setting and not recommended for general driving IIRC. At walking pace trying to turn it felt like it was trying to skip accompanied by a chirping noise.

Lack of Ackerman angle is it not? Every Porsche with large wheels I've driven has done this.
We have had two Panamera Diesels (RWD) on 20" + wheel and they have both done this. The Porsche dealer couldn't find anything wrong and put it down to a characteristic of the vehicle. I seem to remember reading another thread where a chap in a 991 was complaining of a similar problem and someone else suggested it was down to how the electric steering rack operates. Wills2 said:
That's so wierd. I used get pissed of with the noisey diff in my M3. It seems the wheel is being pushed out, but the tyre seems to stretch.
Why can't they make motorsike like they used to or test them before they leave the factory.

We have a GLC 250d AMG Line on 20" wheels and it's a nightmare!
My very, very amature video > https://youtu.be/E9vpoYz0Msw
The car judders, bounces and skips making a clonking noise when low speed cornering such as parking and turning out of or into junctions. Very embarrassing when taking friends and family out - passengers get quite frightened by the sudden jumping and clonking noise, they think we have a puncture. My wife had a situation at the supermarket where a lady heard the noise and bounce as she reversed out of a parking space, she shouted to tell my wife there was a problem with the car
After saving our pennies to get a GLC, I now cringe and have a sick feeling in my belly every time I get into the car - this might sound like an exaggeration, it's truly quite depressing
This may not be related - Also, seeing rapid front tyre wear after only 8.5k miles. A local tyre supplier is estimating approx 2 to 3k miles left in the tyres. So will be lucky to see 12,000 on the fronts - back tyres are like new. This is no super car, it's driven very cautiously by my wife and would expect at least 18 - 20k miles, she got 32k on her previous X3.
We've had other 4x4's and experienced tyre slipping and skipping when pulling away on cold wet surfaces - this issue is very different.
It's a great car, apart from this infuriating fault / problem, so hoping MB will fix it.

I would blame the silly fashion of too low profile tyres in general and especially on cars that have a suspension setup geared to comfort with soft suspension bushes, which are most modern cars really as they need to make the bushes wallowy to compensate for the lack of give in the tyres. Had they had a healthy amount of sidewall, these would just deform under lock adjusting slip angles as they have done since the beginning of automotive history, but not these stiffer low profile tyres and soft bushes that get loaded up. The big rims and low profile tyres are heavy, expensive, ruin the ride, generally skippy and now this. I actually downsized from the smallest size available from factory on my car, 19" to 18". Doesn't matter which car, it's a general observation of marketeers slapping on too big rims. Oh yes aesthetics. Well, learn to design good looking wheels then with the correct rim width and stance and fitting tight arches and a purposeful chunk of rubber around it integrated in the design, instead of just slapping the biggest fugly ill-fitting rim on there the accountants will allow you, and then charge silly money for a larger size again... Bought by clueless consumers that will option up for the sake of it and would buy 'but they were good looking' rims without tyres if it were possible.

My C43 is on 18" rims and it's the first 4WD car I've had with this this phenomenon.
I had a Q7 on 21"s for 2 years and never felt it. An A45 AMG 4Matic I had for 6 months earlier this year didn't show any such traits and our Disco Sport on 19"s doesn't suffer either.
As I said earlier I had an R35 GT-R back in 2009 and although it grumbled during similar low speed manoeuvres, that felt like a "diff" thing rather than the tyres skipping around.

Is the E400 coming be UK? Slightly detuned E43 for a chunk of cash less might be perfect.
I thought this sounded more like a replacement for the E500 than any sort of AMG. The "happier at 8/10ths" comment particularly. I think an E400/E500 equivalent without the faux sporty stuff could be a compelling family bus of the sort I will be looking to buy in 2017. That crabbing and noise has kind of put me off though!At work i drive Merc's regularly and GLC find it quite noticeable, seems to only affect RWD based mercs with AWD not so much GLA and 4matic A Class, but i think system used is quite different. I guess Haldex style based cars dont have the issue as a FWD box with AWD bolted on? Golf R, Audi, FRS?
As above it reminds me of when i had a issue with my Subaru Legacy GTB when the centre dif locked. Once i replaced a plunger on the case was fine and that never had a issue with parking or tight turns.
What has changed in more resent AWD systems to have this issue?

Yup that is my car A GLC43.@Dan - I'm quietly confident that Mercedes UK will issue a statement along these lines which is what they give us owners.
I'd be embarrassed to take a passenger out if my car did that and was a £500 st box. To think this happens in a car that is meant to be "premium", is a real slap in the face. Cue embarrassed silence from passengers, and driver who must feel like his pride has fallen through the floor.
I can't but for the life of me think, MB are treating their customers with an amount of disdain and disrespect, that I've rarely seen before. Appalling. Truly appalling.

Fair point, but also it doesn't say good things about how well they've tested the cars and what standard of performance they consider acceptable. Nothing about that noise and crabbing suggests it's good for the long term health of driveline components!!t box.

It does make you wonder which aspects that are less obvious to the drive but key to longevity are similarly crap. A colleague bought a brand new GLC and it has been absolutely riddled with faults. Polar opposite of our XC60 bought at about the same time.
Every Boxster, Cayman and 911 I have been in does it on tight lock - some a lot worse than others. I assumed it was another bit of the Porsche "character", just like the burning plastic smell after a hard drive, or the wonderful IMS design on early cars...!
It now seems like lots of other performance vehicles do the same - and I would be amazed if it cannot be properly designed out.
It has to be something to do with wheel size...?
