Hi, all. I'm trying to figure out a parts equivalence puzzle.

I ordered replacement shock bushings for my rear struts, part number CCC6782, but what I received has a number stamped 2013520027.

In these forums I see the CCC6782 number but I couldn't find anyone here talking about 2013520027. Some websites say that's an equivalent part, but they only mention Mercedes. Also, the part has a yellow plastic-y end, not the black rubber boot I see in pictures of CCC6782. It's 40mm in diameter.

I haven't been able to press the old bushing out yet, and it might be because I was pressing on the wrong thing. As best I could tell by sight, the shock's eye has a recessed shoulder that's 40mm od and 32.6mm id holding a bushing of 32mm in diameter. Paint on this shoulder matches the green of the shock on both ends.

So, can anyone quickly tell me whether there actually is a shoulder inside the eye of the rear shock or what the diameter of the right bushing should be?

To finish out the measurements, I measure the overall shock eye to have an od of 48mm

 

Here's what I'm referring to. I've already beaten this thing up pretty bad trying to get the bushing out by pressing where I thought the bushing was.

You can see the thing I thought was a shoulder of the eye still with its green paint around its top half. I'm now wondering if that's the bushing itself, just with a weird coat of green.

This is a 97 without fancy adaptive struts.

Yes the shoulder you are referring to is the outer part of the bushing and you need to press there.

I used a rig like this to press out my front ones. Was a loaner tool from auto parts store. It takes a good amount of pressure to get them moving. I vowed to never do those bushings again just due to the PITA factor. Replaced entire rear shocks to avoid that trouble.

Remember to put your new bushings in the freezer for a while before you try to press them in. That helped mine a lot.

Also check the diameter of the bolt hole to make sure it is correct. Some bushings (Mercedes IIRC) have larger hole.

 

Thanks for the tip about the larger hole. I'll check on that while I wait for the seller to confirm that he at least thinks he sent the right part.

I went ahead and turned a tool on the lathe like so many here have so I could do it in the car.

I'm going to give it one more try, pressing in the right place this time, before giving up and just buying new rear shocks.

 

Yep, there is no shoulder, just the edge of the bushing in there. Once I started pressing on that the bushing started to move.

I still don't know whether this new orange bushing is actually compatible. Maybe I'll just put it in and see what happens.

 

Good luck!

As Master Yoda said “Try Not! Do or do not. There is no try!”

 

Glad it is working out now.

How about a pic of the orange one?

Does your shock bolt fit it correctly?

 

Here's a picture of the orange bushing. I exchanged messages with the company I bought it from, and they confirmed that it would be compatible. This after I had already gotten it installed in the car

It went in just fine, and so far it seems to be holding up.
