what is it called?
 

1980 300SD, W116. I need new bushings for this part. It is the round bar that goes under the engine at the rear of the upper oil pan from one side of the car to the other. Is it the sub frame or what. Iwant to get the bushings but don't know what to order. The subframe bushings?

thanks.

Sway bar/Anti-roll bar bushings...I have only ever worked on a 123 but that would be what you're describing on a 123....I think.....just throwing it out there anyone with a 116 want to chip in?

Yep definately don't know anything about 116's:D

Well I can tell you are a little lost, the big round thing under behind your oil pan is called the yoke it fastens to both sides of the frame with bushings one on each side then you have two control arms one for each side and you will need two bushing kits one for each side now this whole systen has six bolts two camber and two caster and two subframe bolts that 6 caster and camber are different bolts the subframe bolts are regular bolts # 8 grade i'm telling you about the bolts because they are sometimes very hard to remove . what I do is remove the whole system and then install all new bushings and bolts and reinstall to car. you can order all this stuff from either phil fastlane or Mercedes classic parts out of california they can order almost anything from Germany in 8 days.Jerry

Question: If he removes any of those bolts will it change his alignment???

hey, thanks
 

Thanks, that tells me what I need to order.

it would be a good idea to get an alignment after you finish all the suspension work.

Now the anwser to that question is yes he would need and alignment, but he didn't ask that, now I could give a step by step procedure on this is done if you would like along with pictures and the workes, I restore Mercedes for a living and a hobbie I have one in my shop right now I'm going to start on Monday I have done several and have lost count by now, But yes it would mean if I were doing it and alignment would be required, but then I have all the tools to do the job right and that has always ment me pulling everything out and re bushing everything subframe and both control arms upper and lower ball joints and bushings and you mine as well replace tie rods there more then likely worn out too, along with checking steering box adjustment and then doing a front end alignment and toe end setting and by the way that would be 0 degrees with same distances front and back of tires, and then a little caster and 0 the camber, but I might just put a repair thread up here with pictures and how to do just that. If anyone really wants to know how to do this a manual is a good place to start so you might have a better understanding of what is required. I don't believe in short cuts I beleive in doing it right the first time and that takes some special tools and mechanical experience and knowledge. but thats my opinion.

Just bought all new bushings, and rear springs for my 116 this week. They call those subframe bushings. Part number 116 333 56 15. Bought them for $12 each.

FSM suggests marking the rear control arm bolts where they mount to the subframe so you can reinstall them in the same position. An alignment would be an excellent idea.

You can check out handbook.116.org for the procedure.

As post #8 suggested could the parts be marked with a scribe of something and if this was done would there be a resonable chance that he could save his origional alignment? (I am asking this as my car is an 84 and some day I will be faceing a similar problem.)
