987 Suspension Clonk?

[Montcoffer]

My 2007 Cayman has an intermittent ’clonk’ when turning on a part lock, from the front suspension area.
You hear it most at low speed while turning up a slight slope.
Bouncing the car doesn’t replicate it.
Any ideas?

They're supposedly quite prone to this, although I've been lucky enough not have suffered it on any of mine. There are parts of the suspension called coffin arms and other parts called tuning forks ( it's a shape thing! ), both seem to be the first port of call for your type of problem. Boxanet's your friend with these things.

Thanks for reply, just checked out Boxanet and they have a good description on the procedure but unfortunately the photos posted weren’t displaying. Cheers

No worries, hope you get sorted.

After a full overhaul including being put on shaker plates, nothing found. Even after 75k miles all bushes in good condition.
The trouble with intermittent faults there so hard to find. Best of it on the ride home my wife heard it while pulling our driveway, test drove with her and nothing??
I hate unsolved problems.

Sounds like Ackerman. If you try reversing on lock and it gets worse it is the Ackerman effect. Save yourself a worry. If it isn't then ???
