It rains and is somewhat windy in our area today... I barely got to work this morning - for whatever reason the car just could not follow a straight line on the highway above 65MPH - if felt exactly as if the rear wheels were intermittently loosing/gaining traction causing the car turning sideways (or getting very close to that). I should mention that my rear tires are low on thread and I do get Traction Control warning light intermittently accelerating from full stop - but this was not the case this morning, at least there was no light...It did not feel like hydroplaning either, it was trying to go sideways with my foot completely off the accelerator...Is there a specific part of the rear suspension that controls car susceptibility to wind?? Thanks!
