The engine mount number your dealer gave you is for a "Repair Kit, Engine Mounting" which includes the mount, a bolt, a spring washer, and maybe some other things (it is hard to tell in EPC). The mount itself is the number that Stretch found for you above in post 7. If you search for those part numbers, there are companies in Europe that sell genuine parts for less than you can get them here. Be sure to search for the part number, and also the part number with an "a" at the beginning, as different companies list the parts different ways.

Part 1162230112 has an msrp of $159 and you can find it for $120 (no shipping charges or tax). I have no way to check if they still sell that particular part number.

Part 1112200017 has an msrp of $382 and you can find it for $287 (no shipping charges or tax). My dealer charges higher than MSRP as well. Given the price of this part, my hunch is that the repair kit includes two mounts, plus a few other bits and pieces. Your dealer is right that EPC only calls for one of these, whereas it calls for two of 1162230112.

Regarding the transmission mount 1162400418, its msrp is $119 and can be found for $90. Unfortunately rubber bits from MB can be rather expensive.

One more thing, Pelican parts has a webpage which states that you get two mounts with the Repair Kit. (I am not recommending this brand, by the way)

Meisterstaz is a German brand, no? Also, are you saying that you can't recommend it because you are unsure of the quality? Or are you saying that you don't recommend because you know the quality is sub par

Good question. Sorry to be unclear. I simply have no knowledge whatsoever of that brand.

Thanks again for all your help. Quick question, do you think this could be the source of that droning noise that i get at highway speed? I'm hoping that the engine mounts and subframe mounts are the source of freeway speed drone noise.

Shortsguy1 · #22 01-21-2016, 12:04 AM

I personally doubt it, but there are others here better equipped to answer this question. I would encourage you to start a new thread with that question in the title. That way, you will get the best input you can on that specific question. Good luck.

What does it sound like? Sure, it's possible that the engine and trans mount are flat and they are transmitting vibrations into your frame but it's usually driveline or even exhaust that's responsible for drone at cruising speeds. Flat engine mounts provide a rougher idle than anything, from my experience in my 4.5 with them.

Hey Tomguy,
Thanks for the quick response. That was my initial thought as well. i was thinking either the exhaust was loud, and might have holes (i couldn't find any holes) or possibly the drive shaft was out of balance?

I did notice my sub-frame mounts are pretty squashed. my mechanic pointed that out as well. So i'm hoping that is the main source of noise. I'm thinking that vibration at high speed is being transmitted into the cabin?

I can't really describe in words what it sounds like. I can only describe it as a droning noise and the pitch goes up and down. I'll try to record it on my phone.

(I'm going to replace front sub-frame mounts and engine mounts anyway as my car has 230k miles and judging by the front sub-frame mounts, i dont think the engine mounts were ever replaced. my tires are new as well.) if that doesn't work at least i can rule it out.

btw. heres pic of my car
Enjoy!

The noise could also be the flex disc or your transaxle. Have you checked to make sure your differential has oil in it? Have you inspected the flex disc? In my mind, motor mounts would make more of a difference at idle sitting still than at highway speed.

Low power steering fluid also makes a droning noise. I would expect that noise at slow speed while turning, not at a steady highway speed.

JeffreyNMemphis · #26 01-21-2016, 02:47 PM

Btw... That is a beautiful car!

Yes. flex disc brand new as well as the drive shaft center support bearing. agree with you on engine mount. but my subframe mounts are crushed as well. my mechanic says my trans mount looks fine but i might as well replace that.

(btw i like your collection of cars!!! stellar!)

If you had a GoPro camera to attach under the car you could get amazing digital sound and video...

Did you confirm your differential gear oil is full? No leaks in the transaxle?

Another wild guess... brake line rubbing against a wheel? Like a baseball card against the spokes of your front wheel?

Dont have a gopro

brake lines certainly not rubbing. changed all the hoses so i would have noticed any rubbing.

i'll check diff gear oil. but i dont remember seeing leaks there. I need to take a test drive in an excellent condition w108 4.5 so i can compare. because maybe i'm just use to the silence of my w124 300D :/

How do I know if I need to replace my engine torque dampers? How critical is this part? I don’t drive my car particularly hard. My regular mechanic said that I did not need new ones. Another mechanic said they are well overdue and I need to be replaced.

I’m not looking forward to spending $270 on genuine MB engine mounts so I’m hoping I don’t need to spend another hundred on dampers.

Thoughts?
