Its static imbalance or an out-of-round tire or wheel. Can also be caused by serverly worn shocks/struts. Have the tires balanced and the wheels checked. Inspect the shocks/struts....

Didnt come from my own brain..

Try vary tyre pressure up and down until wheels don't tramp readily. I think it is a problem of tyres oscillating in sync with suspension. You have to try to disbalance them.

More theory on the subject: it is more difficult to oscillate a stiff system [as in it is harder to dribble a brick compared to ball], so making everything stiffer should help. This includes tyre pressures, dampers, springs, ARB, bushes and strut brace.

You can also disrupt tramp, so that two connected systems cannot oscillate at the same frequency and instead cancel each other out, this is where varying tyre pressure comes in.

The ST is very prone to axle tramp, i used to get it alot and still do sometimes in wet. Coilovers and front ARB do help and you can adjust damper stiffness to compliment tyre pressures.
