I am having a difficult time trying to replace the in bushing/bearing on the inner part of the upper rear control arm. I’ve gotten the outer one out and replaced, but the inner I can’t seem to find the right size? I got the old one out but can’t seem to find the right size to replace it? I have initially purchased the same size as the outer (part #33-32-1-135-131) but the inner seems to be just a slight bit smaller in diameter and also the bolt through the middle is smaller too. Is there a different part # for these? I noticed Wokke sells sets for these but these also appear to be the same size for inner and outer, which is why I thought they were the same part.
If you are referring to rear upper wishbone 33321138015 there is no OEM direct replacement bushing. I make re manufactured units with new spherical bearings, I will not sell bushings only. I do require the cores sent back to me.
Quite a few members on this forum have my units installed and are very happy.

That would make sense why I can’t find the right part, lol. PM incoming!
this topic comes up every few months, you can buy the bushings alone from wokke and another vendor in germany, i have used them with no problems,
if you are not a diy kind of guy then a few members will sell it complete with the arm.
Wokke sells them for 288usd, the other guy on ebay sells them for 210 euros shipped for the set.
Ed does a first class job and you needn't have any qualms about dealing with him.

I got my 850 aligned and Guy stated that these were starting to be worn but not enough to affect the rear toe. What are the symptoms of these going bad?
Great job @dragon850 on the wishbones, got them back today and already installed. Been cruising ever since, Thanks Ed!
Next winter I am going to drop the entire rear end and replace everything
For right now I am starting to get a wobble in the rear so I inspected and jacked up the hubs etc looking for any wrong movement which I did not find
My Left rear which is pictured had a slight amount of top to bottom movement. This is the Mythical Upper Control Arm Bushing. Did not look to be in the greatest shape and its cocked off of center. Is this cocked look correct?

I Checked mine, rear right side upper control arm (Passenger side in US), with the wheel up and no load, i have no wobble anywhere, rear is running perfect.

Just FYI, someone managed to actually use a bearing from Mercedes for this, and had it custom built with spacers:
"I recently had the entire rear suspension overhauled and #10 is available as a complete unit for about $600 for each side. My trusted mechanic used a Merc. ball joint which was close in size and fabricated spacers without making modifications to the control arms the ball joints were only $50 each. I have driven the car for almost 500+ miles after and its pretty solid. "
Hope this helps: "The ball joint is from any 190 series or E-class from the 80s and early 90s. It's the rear lower outer ball joint. However, it is 40mm OD, and it needs to be machined down to 39mm OD, and add 3.5mm spacers to each side to go from 48 to 55mm wide"

Perhaps the poster doesn't know all the work that was done, although he is quite technical and does a lot of work himself. I have chatted with him on occasions and he does appear to be legit technically.
In any case, its something we may all have to deal with as more and more parts become NLA or prices go off the charts. You are looking at $600 vs $50(the ebay link says the bearing was around Euro 24). For DYI folks, budget minded, its something to have documented here.
