Hello,
I have a 2005 C 230 and the collar where the turn signal and the cruise control is loose.
It actually moves rotates when I signal or use the cruise.
There is a hole on the bottom of the plastic cover where there is torx screw, which i checked and its tight. Is there any other screw that holds the collor from rotating.
I did a search and was unable to find anything related.
Any help will be appreaciated.
Thanks in advance,
AL Z

Hmm.. I thought the collar is snap on? Pics?

This is all there is in there:

Is there a bolt that keeps the whole turn signal/cruise control collar assembly from rotating?
If so, where is it located?

Only bolts are shown in the above diagrams.

There are three small screws that hold the turn signal assembly in. I can't see how those would come loose. You have to remove the air bag, steering wheel, and wheel position sensor (round plastic disk) to get at it.

AL Z check out Slammer111's post #75. This is the culprit round metal sleeve that is attached to the plastic housing and causes the unwelcome signal rotation.

Read through the entire thread cause you'll need to dismantle the whole signal assembly (once there is a solution) to get to this sleeve.

I fixed the rotating steering wheel shaft. How? With a ton of Gorilla glue.

Totally seems to work though. Put it on the side away from you, and cram as much of it as you can into the gap between the 2 sliding parts.

My concern is more if it's meant to be this way and something else is broken. Is this sleeve supposed to move this way or is it not supposed to move at all? Is there a screw or adjustment needed? or is the only fix other than putting glue a complete replacement of the steering tube. Anyone else look into this? I am attaching videos for reference. Thanks for your any input you can contribute!

The collar spun rather freely on my car, hence the Gorilla Glue. Looking at the assembly, I couldn't tell what was actually holding the collar in place. Didn't see any notches or holes for pins. I'm guessing it's some kind of poorly designed press fit.

I have seen this a few times. It's a poor design if you ask me. Only the bolt under the steering column prevents it from turning its like a clamp design. I have never noticed anything broken. Sometimes you can pop Mark the sleeve with a centre punch so it can "grab" again. Make that bolt pretty tight too. Good luck

Russell, what bolt are you speaking of? The one that goes with the Turing signal combination switch?

Yes. The T30 torx

I must be missing something then. I turned it till it basically stripped the thread on the combination switch and it still moved. I had to go get a new one since that one broke. Needless to say, I didn't tighten the new switch as much. Not sure what to do.

Pop Mark the sleeve

Russell, how do you pop Mark the sleeve?

Centre punch and hammer

hmm, any center punch you have in mind? I'm trying to see a good one I could buy that could fit the bill. Also wouldn't snacking it with a hammer and center punch break the sleeve? Or cause damage to the steering wheel mechanism? Sorry for all the questions. Want to gather as much info as I possibly can.

Same problem

Not sure why everyone here is ignoring my Gorilla Glue suggestion. Mine hasn't moved in years.

In my case, I would hesitate to glue the shroud together, as it will mean that it will have to be broken apart if any parts had to be replaced in future...

It works. There is absolutely no reason why one would ever need to remove the collar from the jacket. And I mean this literally, having replaced various components in my steering column. In fact the entire jacket (long cylindrical part) including the collar is sold as a single assembly, with a single MB part number.

Afaik the collar is only loose because of a manufacturing flaw. I'm pretty sure it is a (supposed to be permanent) press fit gone bad. Honestly they should've used a fastener during assembly instead. Other people have fixed this problem this way, by drilling a hole through the collar into the cylinder part and adding a screw, but I found that way too risky in case I drilled too far. The glue can always be scraped off or the bonding area split using a knife.

The screw accessible from underneath secures the plastic shroud around the collar. Tightening that does not help as the problem is not between the shroud and collar, but between the collar and jacket.

Hi Slammer111, I was under the impression the problem was purely a loose shroud. After watching the video posted on YT on fixing the problem without removing the steering wheel, I realised what the problem was.
My apologies,

Sorry, I'm joining this thread a bit late. I have exactly the same problem (the shroud, and all three stalks move when using the indicator). You mention a YouTube video leonrsa about fixing the problem without removing the steering wheel. Do you still have the link for that video, it sounds interesting?

Hi Steve, I do not have a link to the video...sorry.
I am sure you will find it when you search YT.
