Shaking

General tip-Always work inward, look for any leaks from suspension or axle assembly parts.

• Shocks-If the shocks of a car are not functionally properly, the vehicle will respond poorly to bumps and to turns, causing the car to vibrate. This can only be fixed by replacing the shocks.
• Tires-Tires can be either misbalanced, or the tread may be worn out or warped causing a lope in the car’s ride, and will be considerably more noticeable at higher speeds. Also be sure to check the lug nuts are tightly secured.
• Engine and transmission mounts – The transmission and engine’s rotation causes the motor to shake, so the motor/transmission mounts are used to vanquish the vibrations. But if a mount it shot, the vibrations are sent straight to the chassy. This can only be fixed by replacing, but you are left with the options such as polyurethane or aftermarket mounts as to the oem.
• Axle assemblies-CV joints, c rings, and CV boot
• Wheel alignment- If the alignment of the wheel is off, the car will pull in different directions at different times which will result in shaking, which will be more noticeable at higher speeds. To cure this, take the vehicle to a local tire shop and ask them to balance the wheels. Will normally range from 20-30 dollars USD.
• Rotors-If a rotor is warped, a caliper may press into them causing to brake on that side only, creating a pulling to either the left or right.
• C Rings-These rings keep the CV joint and boot in place, and if it is broken it would allow the CV joint to come out of place and to slide around. This can only be fixed by replacing.
• Half shafts (CV Boot)-A rubber piece that can either crank or tear. Usually to do with CV joints sliding around on them. This can only be fixed by replacing.
• CV joints-Only if the shaking occurs during acceleration, especially corners. To test this come to a complete stop and turn the wheel as much as possible to one side, then slightly back to avoid overheating the power steering pump, and accelerate. The acceleration does not have to be hard. Do this for both sides. If you hear a clicking then your CV is most likely the problem.
• Damaged rim- A rim with a slight flaw, or the rims weighing different amounts could cause the entire car to shake, and will be more noticeable at higher speeds. This can only be fixed by having the rim repaired or by replacing it.
• Tie Rods- To test this raise your front end up, and lower it onto jack stands placed underneath some portion of your control arms. Then, place your hands at 10 and 4 o'clock and move the wheel back and forth (laterally). Then perform this at 7 and 1 o’clock. If it will wiggle, have a friend feel along your tie rod to figure out if it's your inner or outer end that's got the play.
• Ball Joints- Ball joints are high pressure grease packed bearings. Eventually the bearings become loose so the pegs protruding from them attaching to the rest of the suspension can then move freely. This can only be fixed by replacing the joints. It is typically easier to replace the entire control arm.
