Shaking/vibration at high speeds

[HDJ]

So I’ve had 4 new kumho ecstas put in recently and the shop allegedly balanced all four when fitting them however when at speeds of 100-110 and above the car’s steering wheel vibrates and shakes left to right a lot. I’ve had sway bar links and bushes for front and rear replaced recently could that have maybe whacked my alignment and wheel balancing of my car?.

It should not have anything to do with the swaybars, but worth checking that the Sway Bar is centred on the car, not sitting more to the left or right side of the car. Then go back and tell the tyre guys there is a problem and all them to have a look

Alignment has nothing to do with steering wheel shakes.

Sounds like a tyre balancing issue....Take it back and get them to re-balance the wheels and check that the centre hub is free of debris so the rim is sitting flush on the hub
