M8s was the same before the test when a bottom wishbone ball joint was found to have a tiny bit of play. Changed it for him and the problem is now gone.
I reckon it must be when the ball joint moves the friction inside it causes it to maybe re-lubricate itself and maybe that is what stops the creaking temporarily until it cools down again.
Anyway, it worked for him. The ones he had on before the change to VX ones were the Delphi aftermarket ones and everyone knows what I think of that aftermarket stuff.
VX/GM for me every time, maybe a bit expensive but its less hassle in the long run.

Interesting, i was wondering what it could be as suspension componets don't really 'warm up' But leaving in he early hours hitting the pot holes and speed bumps, it really does crash about, but after a run, feels sooo much better going over the same bumps.
Will jack it up on and check for some play in it all 
take a look at top quality suspension components such as ohlins, these days they have piggy back oil resrvoirs to keep the oil cooler during hard use. Certainly on bike suspension heat is generated as oil is forced through shim stacks as part of the damping mechanism, which causes heat and works the oil hard to the point a service is recomended to change the oil every 2 years on road vehichles with thier units, racing is a far more stringent service schedule.
Car shocks, i've no idea what the internal mechanism is but they have oil in them for damping, oil thickens when cold and thins when warm. I've noticed a firmer harsher ride during cold starts which improves during my comute. The creak does seem to go in conjunction with the suspension starting to "warm up" or become more compliant. New shocks will prove it one way or another. Just a theory, could be a number of things that creak though....?
