What is this poll supposed to be? All of those options could have possibly solved the clunk. And you're overlooking a lot of things... play in the differential, rear shock mounts, broken springs...

I was just looking to see how people have solved their clunk. Im talking about the clunk people are getting when they are shifting.

You should specify that more clearly. I think its usually the CSB/Guibo. I'm currently living with it on my M3 but I plan to address it soon. My 330Ci had the same exact clunk.

Eh if not I'm going to live with it. At this point a car with 155k miles isn't worth investing too much more into with things like clunks. My rear diff bushing is actually so bad that pieces of the bushings are missing from the carrier. So I'm about 99.9% sure that's where my problem lies. The diff tool should be here sometime this week and then I'll get started on it.

Tip! Make sure you hit the axle bolts with some pb blaster because if you strip them its not pretty

I got my rear clunk after around i switched to Coilover around 9 months ago.
i narrowed down to RSM/ diff bushing/ RTAB/ subframe bushings/ other bushings

After reading hundreds of threads/posts. I had my rsm and rtab changed and clunk is still there. So next I am going for my diff bushing.

How much did it cost you guys to get this fixed at the shop.

Expect to pay between 300 and 500. You need to drop the diff and use the special tool to put it out and in. If you have jackstands, a jack and you rent to tool off someone on the forums you could save a couple hundred. Dropping the diff sounds scary but its really not.
