Looks like a lower control arm to me.

This is the cheapest I could find online:

EDIT: Just found this. May be worth looking into such it's a fraction of the OE part's cost.

I admit, I don't know a thing about MOOG so you may want to do a bit of research as to the quality of the bushings etc.

CarHopper

Generally speaking, MOOG has a pretty good reputation for quality parts.

MTV10

I called dealer at it's $700 per control arm. A bit excessive if you ask me.
Good thing I've got an aftermarket warranty on the car. . . .

MTV10

Little update. This is a dealer only part. No aftermarket solution.
Is it normal that a control arm fails prematurely like this? Car has 80k KM's on it.....

On top of it all my aftermarket warranty does not cover suspension parts.

AMG3.2

uhhh there's a Moog part in my post above lol

Not normal but definitely not unheard of either for a control arm to fail that early.

MTV10

That MOOG part is the upper control arm. Not lower

AMG3.2

Okay - either I'm missing something or you are lol but I swear this is the lower control arm.

There shouldn't be a bend in the middle.
See ECS Tuning link below. This is the part needed. MB part exclusively....

Hmm.. Strange. Two things I noticed on the ECS picture.

1) Look at the bushings between the Moog and ECS part. In the Moog part, the hole is slotted to allow for adjustability while the OE part doesn't have that slot.

2) The part number, if you look closely on the ECS piece, doesn't match the OE number which is 2043305011. It reads 2043330060

I'm a bit confused to be honest. Google "C63 Control Arm". You'll actually find that it looks like the Moog part and not the ECS tuning part. That picture looks to be wrong. If what I'm saying is correct, you could save a boat load of money.

MTV10

I wish you were right lol... would save a good $1000....
The part number on ECS is correct. It states it under the description.

Bottom line there are two control arms per side:

1 with balljoint facing down (cheaper one)
1 with balljoint facing up (The dealer only part)

AMG3.2

Totally agree. The part number they list is correct, but it's not the pictured part. Zoom in on the second picture. It says 2043330060 which is obviously not 2043305011.

Hmm let me do more investigating

EDIT: Damn. I think you're right. Why do they have an upward AND downward facing lower control arm?

MTV10

Yeah man if you watch my video the control arm that rattles looks exactly like the one in the picture.

Trust me I was rattled when I found out the price..

Merc63

Almost looks like the movement is where it attaches to the knuckle??

I think I have a used set here. Never seen those go bad before, you must be smashing a lot of potholes hard.

Is the nut on top tight?

MTV10

To be honest I didn't even check... just figured the control arm was shot.

Merc63

Well it's a ball joint in the arm and a nut on top that holds it to the knuckle, check that nut for proper torque.

MTV10

Yeah bud going to check that.
Do you by any chance have the proper torque spec?

Merc63

Tight, I think there is loctite on them

MTV10

Can you confirm that you have a set of these control arms?

The nut on top was tight. The arms are in fact shot. Visited the dealer and they only had one available, claiming the 5011 part number is back ordered.

Please let me know thanks.

shaun.barnard

Hi Guys, mechanic also told my my front left lower control arm is shot. Just a question, are P30 control arms the same as standard C 63?

Jasonoff

Yes.

sytfu_colan

Can anyone confirm the coupes use the same ones?
I see this one on ecs and this other on another website, is it the the same one?

Anyone know the difference between these parts?

Looks like Hardrace makes a set of lower control arms. I've never used them tho...

Did you notice anything beforehand? Any noises or anything?
