My rear diff bushing was bad and I had a noticeable clunk into 1st or Reverse in my manual...and I think your clunk might be something similar...hope so...much easier than diff or trans!

I suppose it could also be csb...I did that too, along with guibo. The bushing is visible and you might notice it squished or noticeable bad otherwise.

And, of course, inspect things...there are other things that clunk...like subframe issues...but no need to go there quite yet...not before an inspection anyway!

Not sure if you already checked, but I had a loud metal clank in my rear as well, check ur rear springs/shocks, might be broken or blown

Don't want to scare you but since you drive a 323/328 you prolly have the same issue I did. My whole rear end was ripping apart from the chassis....good thing I can weld...
all 4 mounting points for the rear subrame were tearing the sheet metal..


Hair line crank under rear seat

This Mounting point fell completely out when i jacked the car up
