I have poly diff bushings in my e46 which are way louder, and I honestly like the diff whine.
I did notice a clunk when going from on/off throttle at low speeds that I don't think was there before the bushing install, but I'm not sure. Could this be mitigated by the driveshaft spline loctite fix? Or is it just a side-effect of the bushing that is unavoidable?
A local tune shop that tunes lots of S58 powered vehicles and has tuned lots of FAST X3M and X4Ms told me that it could also be the driveshaft bearing and bolt? Do they mean diff bolt or is there a driveshaft bolt as well?

From what i’ve read to fix the clunk you need to do the loctite fix. Seems like it’s more prevalent on appearing after replacing the bushing with a stiffer one.
