Wonder if anyone could help I’ve got a knocking on front drivers side been to four garages and can’t find owt wrong it’s ok for a few days when it’s been on ramp but then comes back again 

any ideas 

Worn suspension arms? 

Engine mount? 

Loose under tray? 

Is it intermittent? I had this knocking noise issue recently and it turned out to be the lower rear arm bush. I had those replaced with the PowerFlex bushes and now the noise is gone.

You are not giving us much information to work with. Tell us about the motion of the car when the knocking occurs. For examples is it turning, braking, accelerating, idling, bouncing on rough road, or something else? Does the noise sound metallic or muted? Can you replicate the noise by manually bouncing each corner of the car at rest? A decent sound recording would help.
