I have 2008 S550 W221 (non-4matic)
I experience creaking/grunting noises from front axle when driving over speed bump. I narrowed down the source of the sound to the sway bar bushing.
The attached TSB recommend to glue the bushing (using epoxy).
My question is why glue the bushing, instead of replacing the bushing? epoxy glue is super strong and almost-impossible to detach in the future, if needed

I remember reading about this and I believe the new fix is to replace the whole sway bar, which has a newly designed bushing. No glue required.

thank you for the feedback. Do you know the part # for the updated sway bar?

I couldn't find it in my search, but I'd call your local dealer and ask for the part number and then call an online parts dealer to get it at a cheaper price.

thank you Jtsnyder! I did call the local dealer and was informed the part is# 221-323-17-65
the counter price is $218 and the online price is $126. He told me straight to buy it from their own online store as it is cheaper.
Thanks again for the tips, For $126, I might just replace the whole sway bar instead of glue-ing w expoxy

The new sway bar comes with the bushings glued on. That's why the bulletin says to just glue the bushings if they are loose. The actual bar itself is almost never an issue unless it rusts badly and breaks.

The new sway bar comes with the bushing glued onto the sway bar. Conversely, the bulletin instructed to glue the bushing to the clamp/bracket
