Vibration when making slow left turn in Lincoln Aviator
A vibration or shaking noise and feel is sometimes felt and heard while making a hard left turn at slow speed. I have reported this problem twice to the local Lincoln dealership. They claim they cannot duplicate the problem. We are getting close to the end of the warranty period and I concerned that we may have a large repair bill waiting for us.

Warped brake rotor usually cause high vibration at high speeds. But you can also feel it at lower speeds. But bad ball joints and tie rod end will cause vibration at high speeds. Ball joints will pop at pot holes, sometimes. Tie rods can be felt in the steering wheel at a stop. Move the wheel slightly to the left and right, you can feel/hear a tap as you turn it.
Has to be a drive axle,most likely an inner joint,should be able to feel the play if one is bad (jacked up to let the wheel spin freely).
Also. If the front suspension is weak,or lowered, the CV axle will bottom out in the inner plunge cup and make a terrible vibration.
Check to make sure both headlights are tight,,,when it rattles at idle go feel the headlight and hold it and see if the noise and vibration goes away,sometimes the headlight has too much clearance and causes a massive vibration,,if thats not it try...loosening all the motor mounts and rock the car back and forth and them retighten them,it reseetles the mounts and sometimes fixes the issue,,also check the lower engine and trans mounts for wear.
ball joints or bent rim. Does it click or thunk when turning? It may be tie rod as well. You can lift it up and try turning wheel by hand and shake it to see how much play there is. Check the there is a weight on the rim. Every one is supposed to have one.!!!!
hello have u rotated the tires front to rear then drive and see if u still have the noise and vibration if drive yes while driving slowely turn the steering wheel left to right just a small amount if the noise changes its probably a front wheel bearing if that doesn.t help drive the truck till you get the vibration then let up on the gas pedal does the noise go away if so you might have a bad u_joint but do the tires first how many miles???????
sounds more like a wheel bearing,jack the car up and support with axle stands,then grab the front left wheel at both sides and shake it hard.then grab it at the top and bottom and shake it hard.if a knocking can be felt through the wheel then its most likely a wheel bearing.repeat the test for the rear wheel.also with the vehicle jacked up,spin the wheel and put your ear next to it,if it makes a dry whirring or grinding sound as it spins,this is a symptom of a worn wheel bearing
