Hi Paul and welcome to the LOC.

How did your garage check the suspension components? A visual check would be unlikely to reveal any faults as it needs to be lifted off the ground to take off the weight then use a pry bar in every joint to check for excessive movement.

A lot of garages now have “Shaker Plates” fitted to ramps which simulate road conditions but allowing stationary inspection.

Favourites are as you mention top mounts, lower ball joints and upper control arms. Brake callipers can also cause knocking.

With the cost of new Lexus parts accurate diagnosis is needed!

I wouldn’t normally suggest Halfords but they tend to offer free checks and in your situation I feel a second opinion is required.

The best I can describe noise is like a clattering over any bump.so is a constant if road surface is abit rough.
