I have a very slight vibration in the steering wheel (since a while) when driving above 75mph on highway, mainly when cruising. It seems to be gone above 90mph but it still can be felt at 100mph (enough to feel it in my arm and makes driving at this speed a bit anxious) When I put a bit of gas (to be in the range of -5 ...0psi), it disappears. Sometimes when I slightly turn (left or right), it also disappears. Vibration is only in the steering, not in the seat, so probably comes from the front. I have: new front upper camber arms rose joint tension rods 18" rims with tires in the middle of their life (both balanced when purchased) Eiback + tokico illumina shocks Alignment is ok: -0.3° camber on each side, total front toe in is 1mm. Caster is above 9° on each side (thanks to the adj. Trods)
What I don't understand is why it goes away when I'm slightly on gas.
