Hi all. Hoping someone may have had a similar problem and point me in the right direction. I have a 2012 F-Sport which I love. There is a knocking noise coming from the front, possibly N/S, that is almost constantly there going over a rough or uneven road. She had new front shocks last year and I don't think it's the steering column. She's just had her service at a Lexus main dealer. They were made aware of the noise and even came out with me and spotted the noise straight away. They spent an afternoon going through all the joints,test driving and checking again under the front and frustratingly could find anything untoward. She even flew through her MoT. There is no loud clunk going over big bumps and she is solid apart from this knocking. She also drives beautifully. Has anyone any idea, please?
