Out of Warranty and Steering knuckle fix

Hi everyone,

I am a new joiner from West London, owning a 2017 GLC 350d Prem+.

Has anyone tried to get the steering knuckles replaced/fixed outside of the warranty? any chance to get the dealer/MBUK to contribute?

Cheers

Hi Matt,

No really due to the lockdown has been very difficult to secure a booking and a get courtesy car, though I talked to one of the managers in the dealership and they are happy to try and push Mercedes to pay but no guarantee that this will succeed, though there might be a chance to at least get it partially covered.

It has become even more annoying recently due to cold weather! I am on 20K miles needing the 2nd pair of front tyres!

Its good to hear that they are happy to push Mercedes towards paying for the fix or at least a payment towards fixing the issue. I phoned my main dealer and they quoted me nearly £1400 to carry out the work! I didn’t know weather I could push for Mercedes to contribute towards the cost as I haven’t owned the car from new and it is out of warranty being a 2016. I’d really appreciate it if you could let me know how you get on, if you get them to commit then hopefully it will give me some leverage also! I did look for some after market steering knuckles to carry out the work myself but I can’t seem to find them anywhere other than a Mercedes main dealer who want over £900! The car is really heavy in tires and is begging to drive me nuts.

many thanks,
Matthew.
Unless you’ve driven a GLC to experience the Crabbing fault, it’s hard to describe just how awful it is during the winter months.

The truly amazing thing is, the previous owner will probably have just accepted MB’s explanation that it’s just a Comfort characteristic - complete BS

Many owners just lived with the Fault because it’s a Mercedes 🤔

In their defence MB did finally accept this is a fault and fixed it with new Knuckle Struts - shame they didn’t recall all GLC’s 😞

Keep pushing the Dealer - my understanding is they can authorise up to 60% discounts

Hi Tony, thanks for your reply! Am I in a position to push the dealer to pay towards the fix even though I am not the original owner? I am unsure if they’ll just give me off as I bought the car second hand.
Thanks,
Matt.
Difficult position - the dealer will have had loads of stress from unhappy GLC owners and 100% understand your position. They have been stuck in the middle defending the company line, while knowing it’s a m as manufacturing fault.

All you can do is present the fact that it would have been fixed FOC under warranty if the original owner had simply asked.

Ask what they can do to Fix a Faulty Mercedes Benz

Good luck

do make sure they guarantee that this will fix the issue for you. I had knuckles replaced on my 68 plate in November 19- fine for a while but the issue started again in September 20- now it’s the tyres apparently and I need to fork out for all season/ winter tyres to fix it (which I now can’t afford to do)
Hi,
I'm about to buy a 2016 GLC from an Mercedes dealer with a 1 year warranty. If this occurs and the fix has not been previously carried out do you think they'll cover it under the warranty?
Thanks,
Paul

Ask them if it's been done and if not make it a condition of purchase that its done before you pick it up. 👍

Hi Matthew,

Just wanted to share a little update with you, I finally managed to push the dealer to convince Mercedes to contribute, Mercedes initially agree with a very little contrinution but then I contacted Mercedes customer support myself and further asked them to reconsider this case and they bumped up the contribution, though overall I still paid ~£1100, the original estimated cost was just over 1.8K.

The juddering effect is almost gone, I am still running on my mostly bald front tyres which I am gonna replace before end of the year. Overall I am very happy with the results, I can hardly produce the skipping effect and If it happens it is due to bad front tyres, once I replace the tyres I will further update this thread.

Good Luck

New Knuckles + All Season Tyres is the recommended solution - this combination has worked well on our GLC 250d for 30k miles 👍

Tony....I need more info on this
Hi Mike,

The Crabbing and Excessive Tyre Wear was only a faulty - problem with Right Hand Drive GLC’s

So I think you should be ok in the USA with Left Hand Drive versions

Tony
why is my GLC43 AMG doing this? It is left hand steering.
? - my understanding was left-hand drive GLC’s didn’t have the fault. Only heard of our cars suffering, especially in cold weather & well worn tyres.

MB here in the UK initially recommended All Season Tyres - these reduce the Crabbing but it returns as the tread wears

I would talk to your Dealer

Good luck

Hi Tony,

Wondering if you have heard if MB Aus has a fix similar to this released?
I believe MB Australia have been fitting the same re-engineered Steering Knuckles to pre 2019 GLC’s - not AMG C43 models

Call your Dealer and ask the question

Good luck 🤞

I will need to contact MB Aus to see what they are offering, I am currently in contact with the dealer (LSH Group) at the moment. First suggestion is to replace my already worn tyres to continental SC5 and constantly pump them to 40psi which I think I a joke.

I am requesting for them to provide a more permanent fix. I haven't heard of this steering knuckle replacement before is it 100% after replacement or an on going replacement part?

I currently have a GLC 43 2021 with 21inch wheel.
Afraid you are out of luck with a C43 - different steering geometry and NO FIX 😖

I would suggest Lower tyre pressure - it’s the Stiffness of the tread that exaggerates the Crabbing & Skipping

Here if the UK MB recommend All Season - Winter tyres that are softer compounds and more flexible, Masking - Hiding the fault

These tyres plus replacement knuckles - Long struts behind each front wheel - significantly reduce the Crabbing & Skipping. But it’s still evident and increases as the tyres wear and become less flexible

Our 250d has replacement knuckles but still Shreds the inner edges of the All Season tyres

Over 7 years since MB launched the GLC here in the UK, and shocking that they still sell Faulty C43 AMG with NO FIX. They get away with this because the AMG C43 is the Sport version and other cars such as Porsche suffer from this behaviour. MB had to offer a Fix for non-AMG - Family SUV versions

Lovely car in the summer 😎

Good luck and please let us know how you get on with MB Australia
