Sometimes a shake or shudder will emanate from the engine compartment, because the engine isn't getting enough air, fuel or spark that it needs to run smoothly. Symptoms that might indicate such an engine-related case of the shakes include the following: 1  Shudder or jerking occurs during acceleration. 2  Staccato shaking, as if over a highway rumble strip, within a specific speed range. 3  Car starts and drives fine for a while, but later begins to shake.
The antiroll bar's attaching links can become loose. Check the bushings. Worn-out shocks or struts are common culprits here. When the internal hydraulics wear out, the piston will move without the proper resistance, then stop short when you hit a bump. With shocks, another thing to check for is loose or dried-out mounting bushings. A groaning noise when you turn the wheel typically means there's a dry joint, likely at the idler or pitman arm. That husky stabilizer bar, the part that helps keep a car level in a curve, is often the source of noise.
