    Just thought I'd throw this out there for feedback. My 360 has a slight lateral front end vibration around 60 KPH and again around 120KPH. I've changed the front tires and balanced them(in case I had run on or other wheel issues). The alignment (checked) is bang on. The vibration is still there. It's not large...but its more noticeable when the car hasn't warmed up yet....? Bizarre. I have 2 new ball joints I'm gonna throw on on monday, but it has me a bit perplexed. Maybe a tie rod or even a wheel bearing?
    I'll know a bit more when I pull the wheels.
    Anyone have this problem before? Thanks.

    Perhaps the tires are out of round, this will definitely cause a vibration and when warmed up they will smooth out.

    You could have a bent rim, although that wouldn't fit the temperature dependency.

    It's the tires. Once warmed, they settle down.

    Its most likely not a tire, just changed both fronts and the vibration is exactly as before. I have 2 ball joints I'm gonna put on monday... I'll inspect it then. As one keen F-Chat guy (Greg) pointed out, its probably a slight issue with a wheel bearing that needs tightening...Just wondering if anyone had a similar issue in the past. Thx all.

    Stock Rims or Aftermarket rims?

    If aftermarket, perhaps the tech put the hubcentric rings on incorrectly. ON my car, one of the hubcentric rings that came with the wheels was slightly loose causing just enough vibration in the steering wheel at 80 mph to make you think it was out of balance or was a bad tire..
