Not surprisingly, it depends, if the steering wheel vibrates all the time, no. IT could be a whole bunch of things. If it just vibrates at a certain speed range, roughly 50 to 70 mph, it is probably the tracking on your tires (or at least that's worth checking as it is a cheap procedure).
Either way, if it makes you feel unsafe whilst driving the car, then don't drive it.
Losse wheel, worn bearing, or more than likely, a worn CV joint.
maybe the car need to be linged up n check the power steering.
AnswerIf vibration while stopping, it could be your front brake rotors. If while at idle, then it could be a misfire issue.
what do you mean by unlock, if you mean the steering wheel lock then yoou put the key in the ignition and turn it while you wiggle the wheel
If the steering wheel is loose while driving the steering rack may be going bad. A bad steering rack leads to a lot of play on the actual wheel.
If your steering wheel is vibrating or jimmying while under normal driving conditions this indicates that your tire are out of balance, or have been worn incorrectly. You may have a bad alignment, bad control arm bushings, improper toe/chamber or the wrong tire compound. If your wheel vibrates while turning, then your power steering pump is failing, and needs refurbished or replaced immediately.
Be sure that the mounts have not compressed. Also be sure to check the transmission mount, that it hasn't compressed.
If you put it in 4-wheel drive, and turn the steering wheel real sharp to the left or right while moving forward. The steering wheel will jerk and fill funny. Are you can put it up on 4 jack stands and see if all 4 wheels are turning.
The "clockspring" carries power for steering wheel mounted accessories from the steering column into the steering wheel while at the same time allowing the steering wheel to rotate.
Your 4 wheel drive may be engaged. Take out of 4 wheel drive and put it in reverse. Drive the car in reverse while turning the steering wheel all the way from one side to the other until it disengages.
Steering wheel placement aims to put the driver closer to the middle of the road. Some countries decided differently WRT which side of the road to drive on. Cars made to be used in right-side-traffic have the steering wheels to the left, while cars made to be used in left side traffic have the steering wheel to the right.
Pops while moving but probably not when sitting still and just turning the wheel? One or both of the axles has a torn boot and the CV joint is going bad. Front wheel drive I assume.
