somthing I have noticed, is when that time of year comes and it starts to get below freezing out, mysterious rattles/creaking plastic sounds arise. Don't hear anything three quarters of the year, then BAM. Doesn't bother me, I have noticed this in many new vehicles over the years (only late model vehlicles) primarily Toyotas but others as well. On my 13 4RUNNER, it seems the winter ticks are around the windshield under the dash and somewhere in the rear interior. No desire to hunt it down, just wait until it warms up in spring :thumb:
Also, of course this goes hand in hand with suspension creaks, what do you expect when it's cold. Aftermarket will even be more noticeable with, spherical bearings, uniballs, bushings, differnet material shaft seals, list goes on. Even trying to coat with a lube or coating doesn't do much, when it's that cold shit is thick & stiff.
