Hi Guys,
So this is the engine mount and bolt issue? Has anyone done something that completely resolve the issue?

But my problem only happens when it's stopped and you give it a hard accelerate and you will hear a loud grinding sound while it vibrates. I originally thought it was my tire that went flat and I was driving on rims and caused the grinding noise, then I found out that my tires were fine. So in my case, this only happens at first gear and give it a hard accelerate, and doesn't happen during driving. Is this the same issue as OP?

 

Check out the Diff mounts, normally these go if you're car has a few mods and is pulling plenty of power, they will just rip right out of the floor. An easy one to miss since after ripping off the strut can settle back into the same hole it ripped out of.

 

Ok, let me check with my indy shops for my diff mounts. My car has no mods actually, but I do have a lot of mileage on it though 118k miles

 

My car had 71k when I bought it and these were the motor mounts...The car vibrated like a tanker truck and if I gave it the beans I would literally hear a loud clunk.

A good test is open the hood and power brake the car a bit in drive and reverse, if you see the engine rise up an excessive amount, your motor mounts are shot.

 

Yep those were shot haha. I thought I had ordered the wrong mounts when I replaced them not too long ago, as there was quite a height difference in them

​​​@Pekkle Did you figure out what was causing the vibration? I have similar vibrations in my '97 SL that can be felt in the footwell/gas pedal when i floor it in first gear only. Did motor and trans mounts last week.
Thanks

 

I hope so , this is a 10 year old post.

 

Hello Everyone,

First apologies for hijacking the thread. I have a 2003 W211 E240 with a similar issue. Will explain:

Replaced the transmission about 6 months ago because of an issue where the car was rocking forward in traffic situations. This was proving dangerous because there was no way to control the rocking movement when pulling off. With each surge there was also a slight grinding sound as described in this thread. The diagnosis was that the torque convertor was leaking badly internally. As I live in Sri Lanka it was easier to get a replacement transmission (722.6) than parts to repair the existing one.

With the replaced transmission the above fault is no longer there but the grinding/rumbling was still there, very slightly at first. Over the past few days it has got progressively louder.

-On cold start the vibration/rumbling is most prominent accompanied with a jerk when pulling off.
-When the car has run a few miles the initial jerk goes away but the vibration/rumbling is still there.
- Once everything has warmed up properly and run a few more miles the vibration reduces, but is there very slightly when pulling away from stationary.
- Sometimes after warmed up it is barely noticeable.
- The vibration is not there as it moves up through the gears and the gear changes are as expected, butter smooth.
- In Neutral there is no vibration at all. Reverse is fine, only in forward gear from stationary.
- If I hold the brakes while in D the vibration is very prominent.

Could these symptoms also be caused by the descriptions in this thread engine mounts, transmission mounts, flex plates etc?

Any suggestions are valuable and more than welcome.

Thanks
Roshan J
