These bushings are a lot more firm that the OEM silicone-filled bushes and transmit noticeably more noise than the OEM bushes.

I am not surprised you've noticed more noise, I certainly have.

agreed. i get a knock on some shifts too but it's only been 20km since installing these over the past two nights.

at least the slop is gone!

This gear whine is only under throttle and starts at about 25 mph. Sounds like a siren, gets higher in pitch with speed .Can only hear it with radio off and is speed based, not rpm. Those with these bushings do you have these symptoms?

Yes I have the exact same noise. Glad I am not the only one.
