I just bought a Saris Bones rack for my 2001 Forester and I have a question. Overall I'm pleased with it but on a recent long trip at highway speeds I noticed the upper "leg" would not stay firmly against the rear window and actually gapped about 3/4". This caused more sway than I am comfortable seeing in my rearview. I played with the angle of the legs, position of the straps and position of the bikes. I followed the manufacturers instructions to the letter. It starts out okay but gradually gets further and further off the glass even though the straps aren't loosening. I'm not worried about the bikes falling off as their weight is actually on the lower legs that rest on the bumper and remain snug but I am worried that the sway is putting too much stress on the sheet metal of my car. Plus I don't like the bikes or the rack to move at all because I am a complete control freak so this is making me nuts. Am I overreacting or doing something wrong?
