    Default Chevy G20 shimmy

    My 1994 Chevy van developed a real bad shimmy a few months ago. I replaced the idler arm which was definitely bad but still drives like something is "out of round"? I changed both front tires and rims too. Could it be caused by a bad wheel bearing? It is much worse when braking but it occurs at all speeds. I'm thinking about getting a new rotor and bearings for the drivers side - that's where it feels like it is coming from. Just wondering if anyone else has had this problem. At this point it defintely feels unsafe to drive.

    Have you had your rotors resurfaced? That's the first place to start. Also, you may have brake caliper dragging. Take a real close look at both calipers and rotors to see if there's any sign of rust or damage.
    Good Luck and God Bless
    Remember that if you're not part of the solution, then you're part of the problem!

    When replacing rotors or brake pads, ALWAYS replace them in pairs.

    I had a bad tranny mount on my '85 G30 - acted a lot like that. Just a thought.
