I thought you said last week that you had a broken balljoint and engine/trans mount?

well since i have changed the front left wheel bearing, right inner tie rod end, both balljoints and had a wheel alignment and balance? one of my rims was 5 ounces off would that cause it even though they tried to balance it out?

What about the broken MOUNT? I think you have alot more problems with that car. Was it ever in an accident?

It would help when you start a new thread if you would start by telling us what you've done since the last time we discussed this.

sorry about that but i did changed all the mounts on the car and i might think it could be something as simple as a bad tire GO FIGURE

Ken, not being snippy here It'* very hard to diagnose a problem from 2000 miles away. If you fixed the mount and joint, we need a fresh rundown on the problem.

There are any number of things that can cause that kind of problem. If you think it'* a wheel or tire, rotate the fronts to the rear and see if the problem is there still, or if it changes. While you have them off, inspect the brakes. With the fronts both removed, and the car on stands, put the trans in N (not running ) and spin the rotors. Any rotor/pad clash? Shake the hubs, and inspect all the underpinnings.

Is this still only happening at a particular speed, or is it under accelleration?

Willren is right about rotating the tries around here. When you get the tires balanced it just balances the wheels axially not radially. This is usually caused by a bad rim but if you can pin it down to one wheel (the one that took 5 ounces!!!), try to spin the tire 180 degrees and rebalance and look for an up/down movement on the wheel when it is spinning.

The shake, does it come from the steering wheel or throughout the whole car?
