Gents,

I've searched the forum but haven't found anything regarding replacement procedures for the W210 upper control arms.

Does anyone have these procedure that they can provide?

Thanks, Matt

 

I did the driver side in Jan 2011. For the top side - 1997 320E - Required removing the windshield washer fluid reservoirs (2), then use a socket extension to reach the bolt head under a component (sorry I don't know the function of this part). On the opposite side, I had to remove/move the brake vacuum hose out of the way and then place box wrench on the nut attached to the through bolt. For junction point where it was attached to the steering knuckle, I used an air wrench to remove the nut, then I used a ball joint tool that broke the ball joint out of the steering knuckle. I have seen photographs of this tool on this forum, and if you type ball joint tool mercedes into google search, you might find it. I bought two versions about $30 to $40 each and both were used during the whole job (complete ball joints replacement). Took me several days because I had to figure out how to get to the upper control arm thru bolt. The key was the removal of the washer fluid reservoirs. I am now trying to figure out the passenger side.
