Seems like as soon as it gets below 15 degrees, the PS/Brake Pump groans heavily at low RPM and especially when the wheel is turned. Not only is it annoying, but i have no idea if its causing any kind of damage, maybe the fluid is getting very thick and its pumpin air, i dunno, too **** cold to check. Should i be worried, or just let it be, this is my first winter with the truck

 

it is real common, mine did it bad till i swaped the fluid, make sure you use p.s. fluid and not automatic tranny fluid.

 

Add a bottle of Lube-Gard Power Steering treatment , about $6 from most auto parts stores for no more problem.
