Have you figured out something with this freaking noise?
I think that the struts and coils are mismatched, and in the cold, when the bushings contract, that introduces "play" into the system.
There is another member on the forum here who was able to get Toyota USA as well as Bilstein involved in diagnosing and driving his TRDP and their official response to him was pretty much, "This is totally normal and just inherent to the Bilstein system."
I took my TRDP to the dealer and told them that there was an official case open at the Toyota USA Corporate level and they said it didn't matter because they couldn't hear the clunking on mine when they test drove it. (suuuurrrrre you couldn't....whatever) My guess is that Toyota will not offer a solution/fix for it.
I've talked to a few other members on the forum who have installed the ToyTec lift kit that is specific for the TRDP and they have said that the clunking is completely eliminated upon installation. This is another thing which leads me to believe that the coils and struts are mismatched.
I have the ToyTec lift kit and will be installing it later this week. We shall see if that eliminates the clunk for me. When I have the struts out of the rig, I'm going to see if I can't suss out what's going on. Maybe will even try to mount a GoPro in there somewhere and drive around to see if I can observe any play.
Fingers crossed.
