I'm new here but I've searched the threads up and down today trying to be sure of a question about rear suspension setup.
I just did pads and rotors on all 4 this past weekend and while under the car I noticed these arms in the rear. At first I thought maybe they were designed this way but I noticed both left and right had a different amount of bend to them so I assumed they had to be broken.
I'm almost positive I know what part to purchase but just want to be sure because I've seen this part called 3 different things...
On MB parts it's called the track bar. But when I cross ref the part # on other sites it's coming up with thrust arm/control arm/trailing arm. I'm getting new tires in a few days and wanna make sure I get it done before then. Thanks in advance!
I call them thrust arms. Left and right are the same part #s and interchangeable. The other control arms are usually left and right only, different part #s for each.
When you replace them the Mercedes manual says to rethread the bolt holes in the cover plates going into the subframe, something about needing to clean out the old thread locker to be able to torque the bolts back properly. I have a set im wanting to replace in mine due to worn bushings.
I noticed it looks like the plastic covers is missing also. Theres a top and bottom cover that snap together. I also noticed the thrust arm part # is updated to a 205 #, they should all be the same and fit.
I just got everything ordered last night and will be doing the job this Wednesday/Thursday. Thanks again for all the help and links it was more than I could of asked for!!
Got lucky and the size is listed in the parts diagram.
The bolts are expensive, around $12 at the Mercedes dealer. I bought a set of new stop plates since mine are rusting and will probably pick up a set of new bolts while I'm at it. Mines more of a preventative maintenance so not in a rush to do it.
