Here, try this. The green line is the brake hose that goes to the caliper. The magenta line is the sway bar. the part your pointing at is what looks like a sway bar link. Although the sway bar link and sway bar do not look original. How long have you had the car?

But can it really be the sway bar link? I mean, I'm looking right now at the PP catalog, the rear suspension page for my car, and it shows as a sway bar link exactly the same shape as the picture that was posted earlier in this thread (showing a sway bar link). This thing doesn't look like a "homemade version". Are you positively sure about what you are saying? Rino P.S. I am deleting my previous answer to your inquiry, since it was wrong and might mislead others...

I'll check again tonight if some part of it fell where you said... It would be one of the easiest fixes imaginable... Rino

Hi Larry, I don't know how I could possibly have missed your post, but I did... Both rear wheels do not spin freely, seems like brake dragging of some sort to me, but they are not locked, nor nearly locked... Although not to the extent that it has occurred two days ago, this might have been going in a milder form for quite some time now... This is the first time in two years that I have looked into it... I know, very negligent on my part, but this has changed for good now, believe me. Pedal pressure was fine when I drove the car last two days ago... No, the brakes have not worn down metal to metal, there's a 2 or 3mm left in the rear pads before the metal backing. Does it make sense at this point to bleed the system (the car needs it anyway... that's another thing that was never done during my ownership of the vehicle) and change the rear break pads, and then start from there? Thanks, Rino

Its a sway bar link
I just looked up the rear axle shaft flange R&R on the mercedes cd manual. main function group 35 sub function group 130 (35-130) It shows a picture of the backing plate , holes for caliper and the sway bar link attached. Apparently a "79 240D has a different link than what is on the newer models(plastic). The picture that Rino posted is the end of the link. Looks like the connection part is pulled out of the link (rubber grommet mounted ,possibly). As far as the noise ,either the link or sway bar wedged to cause rubbing or there is problems with the parking brake shoes. just my 2 cents

parking brake shoes Noise???
The parking brakes are a separate set of brake shoes inside the rear drum/disc, I'll bet you'll find the drag and noise coming from the shoes dragging metal to metal. You'll need to remove the rear disc.

So, on the left side, the sway bar is still connected to the backing plate on the hub. I bet the bushing at the backing plate on the right side is missing. The bushing is in the street about a 1/2 mile from your house, and the nut that previously held it is now captured inside the cavity that houses the parking brake shoes, and is rattling around in there.

Should I go ahead and order the rear pads? change those and do the bleeding. And about the sway bar links... how do I do that? I certainly can't order the commercial ones that aren't going to match to the custom items that were installed in my car... right? Rino

Brake work is within your reach. Since the rear brakes use two pistons, take a look at the pad thicknesses of inside pad vs outside pad. If they are drastically different, then you probably have a seized piston, and you should go ahead and replace the caliper. The sway bar link is not rocket surgery either. It's pretty basic, it just bolts to sway bar nad backing plate, and must pivot to allow suspension movement.

Before opening up the brakes to that extent, do you advise I should get rear brake pads, parking brake shoes, and what else. I'd much appreciate sound advice here, since I have no idea how to go about it smartly. Can someone suggest what specific brands are advisable for my car? Besides, what range number of chassis does my car belong to? How do I find that out? I need that in order to properly order the brake pads that go with my car.... Your help is greatly appreciated. Rino

One of the challenges here is to find a replacement for those blown sway bar links... Rino
