LOL, Please..... don't try mixing BRITISH into this mess also...

As an old guy I have more experience ( it looks like ) in this nomenclature mess.

They are calling things different names now in some instances.... but the tie rods are not included in this mess...

The Control rod on my Ford Pickup for instance attaches to the lower A Arm and keeps it from being deflected towards the rear under braking for one example and hard cornering, etc.
It is at the lower part of the firewall near what would be under the left foot of the driver on the left side and goes in a horizontal fashion to the back side of that lower A Arm. There is a matching one on the other side.

In the old days of ' live rear ends' which none of you have in your MB... a track rod was a rod which attached to the middle of the rear axle to help keep it in the mid line of the automobile during cornering. It runs 90 degrees from the long axis of the car behind the axle.

I just had a knowledgeable mechanic tell me I had to replace the inner left tie rod on my 82 300D. (Knowledgeable means "can change a tire without causing undue harm.) I went to a parts place on the web, ordered a tie rod and after it was placed I checked the thing under the car. They do not look the same. Anyway, the MB repair manuel calles them "track rods", and they are between the wteering knuckle arm and the intermediate steering arm. It is procedure 46-540 if interested. I tried to copy the picture to this answer, but the machine won't let me without I do some machinations.

Hope this helps.

When I get the tie rod delivered I will have to return it and order a track rod. Probable will get both sides this time.
