Mercedes AMG GLC43 Geometry Check

Today I’ve had an independent geometry check performed on my GLC43 AMG. It was something I hoped my Mercedes Retailer Service department would have done the first time I reported this issue but unfortunately they didn’t. My tyre wear became so significant that I felt like I had to take matters in my own hands. As such I contacted a local (to me) company who have a very good reputation to perform this activity.

It should be said that my Mercedes retailer did offer this service as well yesterday, but in a joint conversation we agreed that I would continue with the independent GLC43 geometry check.

Below are the charts as recorded during the GLC43 geometry check, these are print outs directly from their Hunter system.

Next steps

My Mercedes retailer service department has accepted the results in principle. There is some verification ongoing regarding the correct parts (Control Arm plus Correction Bearing?) that will be required. But the vehicle should be booked in within the next week to get at least this part resolved.

The cure?

Will this GLC43 Geometry Check result in the cure for crabbing? Honest answer is that I don’t know. It is definitely something that must be rectified to ensure it is not enhancing the experience or masking other issues. I doubt it will be the full cure for the violent shaking, juddering, skipping and crabbing that is being experienced on these vehicles.

It is also not clear whether this is the same on other vehicles. This GLC43 geometry check was specifically done on my vehicle alone.

So one step at a time. My dealership is responsive and have agreed to try and rectify this situation. After that we will see what the effect is on the experience of the crabbing of this vehicle.

A further report will follow undoubtedly next week.

    Hi i too have a glc43 based in melbourne. I have this crabbing problem too. Especially when the road is wet. Trying to park the car, three point turns. Getting in and out of my drive way. Did this wheel alignment help you?

      Unfortunately it didn’t. All was ok from that front.

      What changed it or masked it was the switch from MO marked tyres to Star (BMW) marked tyres.

      I too am suffering from this issue on a glc 43. I have contacted dealer and they responded that the wheels are grippy?!? I have been told others in Melbourne have had to have their wheels replaced 3 times in 10000 k’s and Mercedes bore this cost. I have had enough of the uncomfortable noise and shudder and the strange looks from people near my car.

      I have this issue in Sydney Australia too. My dealer is proposing a change to star rated tyres. I will do this in the next few weeks but ir cant possibly fix the issue. Maybe mask it. I am also concerned that after 5000kms, the front tyres are 90% worn

      I ahve a glc43 in sydney australia with this issue. My dealer did a wheel alignment and corrected some minor discrepencies. This actually made the issue slightly worse. They are now proposing a change to star rated tyres. I dont see how this can change anything. In addition to the safety issue, i am converned that after 5000kms, the front tyres are 90% worn.

        Unfortunately I’ve now done 9k miles on those STAR marked tyres. They are better, but it isn’t a cure πŸ™

          Thats exactly what I thought. Although I am surprised that you could get 9k miles from a set of tyres.

            I’ve had 2 sets of MO marked Sport Contact 5 in about 7k miles πŸ˜‰ Naturally Mercedes blamed me, blamed the size of the wheels, blamed all wheel drive, blamed my driveway, everything really except that they have a problem. If I didn’t have my GLS from that same dealer which is also on 21″ wheels I wouldn’t have been able to argue it with such confidence. That is the part that annoys me the most. Problems occur, but at least try and rectify them and not wriggle out of them.

            I’ve had 2 sets before 7k miles on MO marked Sport Contact. They blamed everything, my driving, my driveway, all wheel drive, large wheels, except that their vehicles have an issue. That is what annoys me the most that they are still not treating it with the due care that it requires.

    Isn’t the car deliberately cambered in this way to improve handling characteristics?

    My C43 Coupe has significant wear on the outer edge of the front tyres only. Correcting this will result in more understeer in corners and a less balanced car mid corner.

    The front sliding at slow speeds is irritating but also a characteristic of AWD cars. My 2011 S3 used to do the same thing.

      No it is πŸ˜‰

      This is now very well documented and acknowledged by Mercedes that there is a difference between LHD and RHD vehicles. And no this is most definitely not a characteristic of AWD cars, I’ve had plenty including Audi/VW and Mercedes and they do not have to do that.
