My TRD doesn't rattle (yet), I am yet to see if I have a fast and furious problem at high speed (hopefully my car wont fall apart). I have had a slight pull to the left, but I also need a wheel balance and alignment. So, until they are done I can tell if the pull is due to build or alignment. The only thing I've noticed is the front suspension is a bit creeky in the mornings when it's cold, but once she's warm I get no noise.
