Knocking on front o/s, unsteady over 60

You could swap the wheels over to see if the knock moves though with unidirectional tyres you'd want to swap the wheels back straight away. Could be a balancing weight loss or a buckled wheel that a quick wheel swap would confirm or rule out.

Taking it in tomorrow but any ideas.

Knocks on front drivers side and feels unsteady over 60 70.

Anything common that causes this ..

Cheers guys

 

All the obvious really, ball joints in the top and bottom arms, track rod ends and suspension arm bushes is the first

places i'd look, if any of those are worn it'll affect the geometry and make the car feel floaty/unstable at speed

I've had this issue for 2 years now. Knocking at low speed and high speed when hitting the brake. Brake vibrations and vibrating at anything over 80mph. It seemed to go away when I'm entering a long left or right turn but as soon as I go straight, it comes back. The vibrations are so bad that it unscrews the screws in my steering boss. I've literally just taken this video so I still need to get it fixed and see if the issue goes away. You can also check for loose caliper bolts. Anyone else ever had this issue?
