Wheel llug but replacement

Does anyone know if it's possible to replace the ML 2012-2015 W166 wheel lug nuts with far more convenient wheel studs? If so is there a kit, dealer or such that provides the studs?

Anything is possible - but the question is why would you want to do that on an ML? On a race or track car where you may have to change the wheels trackside four times a day, absolutely - but on an ML it makes no sense whatsoever. It just adds complexity and may possibly be outright unsafe due to the higher wheel bolt torque required than on a car that studs are usually made for.

In practical terms, no.

If you want to reengineer a hub and bearing with a machine shop, yes.

There are no lug nuts on a Mercedes, but rather wheel bolts.

Don’t go down this path, you won’t enjoy it and it will end poorly for you.

The reason is that when you remove a wheel then go to replace it it is a hard job trying to hold the wheel in place whilst trying to get the bolt in; if the bolt is fitted to the vehicle it's far easier to just place the wheel on the hub and then just do up the nuts.

Yes, but MB didn’t design it that way.

You know about the wheel installation tool, correct? It’s made for the very purpose you are writing about in your posts.

Agreed - but in general, common sense would dictate that solutions that make tire changes ~4 minutes shorter maybe once a year should not come at a significant monetary expense and in particular not with an increase in complexity and possible risk to safety, especially since other solutions that alleviate the minor inconvenience without costing an arm and a leg or introducing unnecessary complexity readily exist. Have a friend hold the wheel up or just get a centering pin if you're doing it alone.

^ This.

You can buy one from Amazon for under $10 like one of these
Amazon Amazon
Amazon Amazon

or for about $3 directly from AliExpress like this one
https://www.aliexpress.com/item/4000173756744.html

You just need a wheel centering pin with a M14 x 1.5 thread pitch.

IIRC there's a centering pin in the Benz tool kit by the spare tire. Never had the need to use it so I can't say 100%...

There are five shorter bolts for the spare donut wheel, but I haven't seen a centering pin. Then again, I've got like six of them from my previous P-cars so I haven't really looked myself either...

I'd never heard of these, thank you. As someone said on another post "It's only a few seconds extra work and only once a year", in the past few weeks I've rotated all wheels and had 2 of them off to repair punctures. Plus I cover over 1000 kilometres a week so tyre changes/repairs are more often than once a year unfortunately. Re the comment about getting a friend hold the wheel once unfortunately here in Australia it's not uncommon to find your nearest friend could be 500+ kilometres away and no passing traffic for hours if not days

We live in very different environments indeed mate... there are days when I'd pay a serious amount of money just to be 500 meters away from someone, never mind 500 km. Yes, one of those pins will do the trick. I've been around cars and people wrenching on them for most of my life and I erroneously assume that everyone has seen the same things and tricks that I have and that they ought to be obvious, but that is definitely not the case. Sorry - and cheers!

No need to be sorry, I've just ordered one, that will save me heaps of back aches etc.
Re the distances, my wife is indochinese and the first time I took her on a trip was from Melbourne to Darwin, about 4000 kilometres, and she found out fuel stations, towns and even houses can be 500ks+ apart both her and her family freaked out.😂🤣 Like many other places around the world 100 kilometres is a big trip. When I was in Tasmania a trip to work each day was a 600 kilometre round trip.
