I have a 2000 lincoln ls and my steering wheel shakes

tire seperation,,bent wheel,tire out of balance,,,very loose tie rod ends,,prob. a tire trying to seperate,,,b careful

like a bad tire or out of round tire..it will make a slight thumping sound while driving..and maybe shake the entire car at low speeds or shake the steering if in front..

When was the last tune up? may need coil pack, plugs, air filter, oil, motor mounts could have gone bad. If you have not done any service to the vehicle a standard tune up of replacing ignition parts is key to do before troubleshooting any issue.

Good luck.

Depends on how the shaking is for the car, it could be a few things. If it sounds like it is running terrible and shaking, the chance is that it is the MAF (Mass Air Flow Sensor) which is located along the air intake pathway for the motor's air intake. If the sensor is faulty, then the car can vibrate but also blatantly sound like it is running rough.

If it is your steering wheel shaking while braking and not the car, then your brake rotors are warped from wear due to braking habits with dragging the brakes or a lot of heavy braking - created a high heat situation with the rotors to warp the metal.

If you recently had your tires changed, it could mean an unbalanced tire. Also check to see if your tires has any bulging from possibly hitting any curbs or potholes recently.

Most likely a tire that has a broken bet,or there is a front end part that is bad.

could be a wheel is out of balance.
maybe you had a wheel weight come off and it's not in balance now.

With out more details I would suspect alignment and or uneven tirewear,or perhaps a tire is failing,
let me know if this helps

the wheel shaking sounds like a wheel balancing problem and the no steering response is either some loose ball joints or a bad gear it will need to go to the shop for both

Hey i just had this same sounding symptoms with my 2000 ls. It turns out that the ignition coils were failing (2,6,8). Just replace all of them. All of them i got on eBay for 150 bucks when the garage quoted me 1100 bucks. Good luck man.
