2014 Bluetec motor mounts
Just had the motor mounts and granny mount to cure vibration at idle and actually higher speeds. One was totally broken and you could see on the other one where something had been “leaning” on it leaving marks. What a difference! My Wife thought I put new tires on it! Idles like when it was new and even higher speeds it is just like new. Great repair, $2200 just to save the obvious question. Be aware the price of parts varies between dealers, so be dealer I use a lot was $200 higher price on each part

On my I4 Bluetec the MM cost me like $300-400 and about 2 hr of work.
MB started using cup-shaped MM on sedans in late 1990's. When they do great job, they don't last and 100k miles is good life for them.
When they are hard to judge due to shape and access, I develop a strategy
"when in doubt- replace them".
In my case the difference was not drastic, but still noticeable.

ML are all 4-Matics, when E come with RWD or 4-Matic option.
I am die-hard DIY and $1900 saved on 2hr job looks good to me.
What job do you do, that pays more?

2014ML 350 Blutec
Kajtek1, thanks for all your knowledge and past help with folks on this forum. I agree that diy can be much cheaper and I have done many jobs in the past on my Benz’s, specifically motor and trans mounts on 3 123 diesels and 2 126’s. That was then..today Is different for many as living in a retirement community in Central Fl does not give a diy’er like myself the opportunity to have a lift or much room to do a lot of other things that happened in the past. I do take pleasure that using your savings theme I found another Dealer I also use that was nearly $950 cheaper for same job—much higher on parts and labor. Also, not having transportation for a couple of days is not an option for Wife that may need quick transport to medical. The included loaner car-both dealers- is a must have for us. The thoughts of having a lift outside or in my garage is a thing of the past, and I am jealous that you have such easy access. Anyway, the ML is running and feeling just like new. Glad we had it done! Best wishes for a great day!

Yeah., retirement community is not for DIY mechanics.
I inherited some money last year, so decided to buy a condo, who is rental now and will be backup for us when/if big house will be too much work for us.
For some reason >90% of condominiums in Las Vegas do have carports only, with only roof, where sun is baking paint on car sides. Took me quite some search to find condo with single garage and a view different than opposite building wall.
Can't have everything.

Assuming your GL is similar to my ML I've done a lot worse and I'm just an amateur wrench puller. I've got a 2 post lift so that helped a bunch but you could do it on jack stands from a creeper. Doing it that way lifting the engine would be a lot easier. I don't have a transmission jack so I had to Rube Goldberg a stand to lift the engine. You don't need to lift it much but you do need to lift it. When you're putting the new mounts in watch the wire closely so it doesn't get pinched.

I was replacing lot of MM in last 30 years, when not having the lift and most of the cars took 2 HR.
2014 E 250 Bluetec was 1st car in my recollection, that require major part removal for access, but still not that much time consuming.
Can't tell much about your vehicle, but check the videos. I bought special wrench for MM removal and could not use it on my E, but it works on some models.
Getting such tools in advance can save lot of frustration.
Usually 1 side is always much easier, than the other, so you can plan on doing the easy side on 1 weekend and get ready for hard side the next weekend.
Pride on DIY and saving lot of money - PRICELESS.

I just had this done on my E250 4Matic. Dealer did it. $2000. They split the subframe to accomplish it.
I assume it's a much easier job on the GLE and the non-4 Matic E250's.
Turns out my sub-frame was rusted. So we ended up installing a whole new rear sub-frame under warranty. Inspect the sub-frame on your W212 E class!!!

IMHO replacing MM is 1 of the most rewarding job for starting DIY.
There is not much risk involved, you don't need expensive tools and you can learn a lot about the undercarriage.
As I mentioned above E250 Bt was the 1st car on my record, who needed major part removal for passenger side MM replacement.
But I did DPF removal in the past couple of times, so with lift and the experience it become 20 minutes job.
Other learning curve on E250 was plastic oil pan, so I had to find new lifting point for jacking up the engine.
You will not gain the experience, if you stay away from the job.
Than about $1500 saving on labor cost sure is good incentive.
In what profession you can make $1500 (tax free) in 3-4 hr?

2013 ML350 Bluetec
I don't know the specifics of your vehicle but that sounds incredibly unlikely. Access to the mounts won't be easy but engine removal also won't be necessary. You will have to lift the engine a small distance. I did my ML350 about a year ago now. Cheaped out on the purchase so the Chinesium mounts I used have already failed. On the plus side I did not change the transmission mount which clearly I also should have done. So all three are on the list now but that won't happen until we get back home in the spring. I wouldn't call it a hard job but its a fussy job. You have to be careful because its tight quarters and if something slips at the wrong time it could cost a finger.
