Well today was my first day ever taking the 'maro out on the road!

Everything went awesome it was keeping cool around 160 degrees while cruisin but when I put car into neutral and try to slow down quickly but not insane, I get a bad shimmy or vibration which seems to feel as if it is coming from the steering/front end somewhere. Although, when I am downshifting rather than going to neutral it doesnt seem to do it. Could it be an idler arm?

 

Please please!?!?

 

Out of curiousity, when the car is gear and you are not accelerating does it vibrate or shimmy? Could this be a tranny mount? Personally I dont think it is the idler arm, although if it is worn maybe that could be making the situtation worse. What makes you have an idea that it is the idler arm? Strange guess... 1st thing that I would do is visually check all the parts, takes less then 10 minutes with a jack and jackstands...

 

It's probably brake rotors, you'd have to do a little more "process of deduction" while driving to be sure, but it sounds like brake rotors.

It could also be a centerlink or tierods, maybe the sleeves also. Those are the first things I would check if brake rotors have been ruled out.

 

Rotors is a good idea, but I would think that it would be espically noticable when not in neutral as well as in neutral...

 

Sorry I didnt have a chance to check up on anything tonight. The trans mount is brand new. The thing is when downshifting your fine but when you go to neutral then brake, and THEN put it into a gear, the shimmying happens. It is as if you almost have to come to a 10-20 mph speed limit to stop the shimmying/crazy vibration. Rotors appeared new on the car when i took wheels off, although it sat for 5-7 years so, I'm confused!

 

What does being in neutral have to do with it? Does it really change the situation?

Or, is it really, just brakes/no brakes?

If the brakes make it do it, it needs rotors. Doesn't matter what they "look" like. One of the things I've seen happen to them is, the car sits in one place for along time, the pads stay against ONE place on the rotor; and it corrodes differently there, and you get those vibes. Because of the rotors (no matter what they "look" like).

Rotors are DIRT CHEAP. You can change both of em for less than ½ the price of a tank of gas. They're so cheeep, it's almost worth substituting some cheeep chinesium ones, and just see if it goes away. Then if that fixes it, go get some decent ones.

If the brakes are not involved (i.e., it does it even if you're just coasting) try swapping the tires front to rear.

See my signature for a list of helpful troubleshooting suggestions.

 

Braking is what causes the shimmying. Downshifting and not using a ton of brakes to go from 5th and downshifting through the gears to 2nd prevents the shimmying totally. I think i messed up the post previous although I just corrected it. What I dont understand is why it does it when you use a lot of brakes and when you dont use much to go down maybe 10 mph it doesnt do it?

 

Idler arm is bad and outer tie rod......HORRIBLE

hopefully this will solve everything

thanks guys!
