How on earth did you find the part# for that bushing? I searched tirelessly for it years ago, then ended up replacing the entire arm. Its not shown on the EPC either.
I, too, searched tirelessly, but allow me to walk you through my mental process at the time.
I searched by all sorts of keywords and part numbers until I got lucky; I found this item on amazon:
that seemed to be related.
At the time of writing this, it still has only one review:
and the guy said it was for the W211 4Matic. I purchased this Febest bushing (see the unboxing picture below), but turned out to be a cheap chinese after-market that's even more expensive than the LEMFÖRDER. I did not know LEMFÖRDER's part number at the time!
I started by comparing the febest part to what I saw when I jacked the car up for inspection. The rubber pattern, the alumimnum shell and core, and the sizes seemed to match. When searching for https://febestparts.com/ARM_BUSHING_...R_ARM/BZAB-038
, I found a lot of pictures coming up in Google images with the 4Matic lower control arm and that bushing was very clear to match.
When I received the Febest bushing, I took the measurements (check pictures) and compared to what's on the car. They matched. When I received Febest, I had already found the cross reference part numbers:
SWAG 10 92 1540
FEBI BILSTEIN 21540
MEYLE 014 033 0091
I just had to return Febest and get the LEMFÖRDER. It is available on eEuroparts and FCPEuro. Of course, I had to pay for the shipping back to Febest USA
, but at least I learned something and got the OEM brand!
