What could cause the car steering to shake at high speeds, shakes the steering and the car itself vibrates

Also notice the cars gently swings left and right at low speeds of 40km

Change your tyres, most especially the front ones ....Also ask your mechanic to examine your brake caliper.

Do wat the above poster said. Check tyres and psi (pressure) levels.
Also check your shafts and engine mounts(seating)

My 4 tyres are brand new

Less than two weeks old

This stuff is not allowing me to enjoy the car when driving between towns or travelling

Check your inner tie rods at the ball joints with the steering rack. And check the steering rack itself.

When you touch your steering during motion how much delay do you get before the car responds? Check steering rack through an experienced mechanic.

I had a similar issue with my car, take the back tyres to the front n see How it goes. Another thing is the caliper

Let's start from this.
Is this a FWD or 4WD.
1.If latter check propeller u joints and plays at the joints.

2. Check CV joints, inner shaft cup for play.

I just solved this yesterday, one of my new front Tyre has swollen

Got another and problem solved,

Remove the front Tyre and run your hand through it

Check your tyres, ensure they are not over pressurised. Check for swellings.

Remote diagnosis is difficult.

Was this problem there before you changed your tyres?

See online mechanics full everywhere... OP abi victim, your brand new tyres does not mean they are good, na China tyre u buy, there are swellings in those front tyres whether bought yesterday or brand new.. Go and examine the two front tyres very well.. You will need to change to real original tyre or go buy real tokunbo tyres and the vibrations dissappear in no time.. Don't let anyone deceive you. Some brand new tyres are roller coaster to heaven, in no time, that tyre will blow out if u continue using it

Hmm
But the wheel balancing people would have spotted tyre defects
I suspect some mechanical components

Two words, wheel and balancing. Due to your tires or bent wheel.

I know you stated it’s been done.

Did you buy name brand tires or generic? Nothing but the best tires should go on any vehicle in Nigeria regardless of the economy.

Majority of people have told you it's your tires. Go elsewhere and have them check your tires. New or not, cheap or fake will have defects.

The other obvious causes you ruled out should also be rechecked elsewhere.

What the wheels balancing people cannot detect, experienced road side vulcanizer will detect that in no time... Wheel balancing people are salary earners, vulcanizer is an hustler and understand the streets better. Everything no be machine, machine machine

Bad tire will be making the car shake or bounce at low speed not high speed of 100km/hr.

The two most likely cause are wheel balancing/alignment or Bad inner hub

You are wrong sir... Rather vice versa is the case.. Poor wheel balancing and aligning will only result in uneven wear on the tyres

It's not a tyres problem

It's the inner cup

If brand new tyre does seem. The company I patronize would take them back

Check the wheel hubs. May i also ask if its noisy on motion as well? If its vibration is coupled with noise, change the hub ..including bearings. inner cup too.

Try to find a shop that do road force balancing instead of just spin balance.

Changing the break caliper helped and alignment after that

Look for a good mechanic to check the steering rack and pinion.

Change your front rotors (disc). I had that problem before and the problem was eliminated immediately I changed my front rotors and balanced my tyres.

I bought new discs though

Works fine now

Just little wobbling but its okay

What’s the brand of tyres you’re using?

Have you checked your engine seating?

The little wobbling is from the unbalanced tyres. Do wheel balancing and it will become perfect. Do this and thank me later
