    I have a 1992 Chevy K3500 Dump and occasionally when I am driving the front end (wheels) and steering wheel go into a violent shaking pattern that will only stop when I slow down. Most of the time the truck performs perfect, but when this happens it scares the sh#t out of me!. Any ideas as to what the problem could be. Thanks for your help

    rotate the tires and see if it still does it. Sometimes you get an irregular wear pattern on the tires and it will do that.

    Must not scare you to bad if you have not had it checked out.

    Could be front end falling apart and you might loose control of your truck. Get into a shop before you possible kill yourself. :hammerhead:

    We are only guessing what is wrong.

    Hi JL,

    I had this problem just as you have discribed, same model truck.

    The upper and lower control arm bushings are shot. They will replace the u + l control arms w/new bushings, and ball joints , tie rod ends (if needed).

    In 1997 it was a $1,200 repair. If you have the proper tools, you could do it for less yourself, and then send it for alignment.

    Get it fixed....Dangerous!!!

    while a bad tire can cause this type of steering feed back it is a sign of a larger issue. You have busings, TREs, or other components SERIOUSLY loose in your front end, get it checked out soon before something happens that injures either yourself or others.

    FWIW, a good front end, properly aligned, should track straight and have no vibration or wheel slap at any speed or condition.

    I didn't think Chevy was affected from death wobble. Its dangerous you should have it looked at you can get in accident. Tires are a big offender but if you have loose ball joints and A arm bushings worn out you need to have it replaced.

    Good Luck

    Most of the time a vibration that comes in like that and goes away after slowing, is related to a worn idler arm. This is part of your steering linkage. It may start after hitting a bump, shake, then get better as you slow down. Other components can cause similar symptoms though. I would take it to your local alignment shop for a check-over.

    impact shimmys ive dealt with were idler arms or drag links. any good alignment or spring shop can fix you up.
