been there! 
most likely its the ubolts on the front end aren't tight enough...
get under there and check em.. maybe even get a breaker bar on em to tighten em up good (others may disagree with this).. if they are old, maybe get new ones, cos they stretch which could be why you are having issues now.. if you replace ubolts, you should check/re-tighten them after 500kms as they will stretch a bit when new also..
I thought it was my front bushes flogged out, but when i swapped diffs with springs attached i had a HEAP of play on one of the spring packs cos the ubolts were loose..

if thats not it check your wheel bearings..
jack up one wheel off the ground, grab it at 12&6 oclock and try and move it back and forth, do the same at 9 & 3 oclock.. if you have any play you might need to replace wheel bearings or tighten the lock nut in there..
not sure if sloppy tie rod ends could cause this, but check them while your down there..

If it turns out to be a balance issue then I am able to supply MAGNUM, a tyre balancing compound, that is simply inserted inside the tyre and balances them as you drive.
As a suggestion, if the prob only occurs with the Micky T's and not the ATs then it may be a balance issue that sets off the "real" problem. It may be, as already posted, wheel bearings or U bolts and that will need to be rectified. By balancing the tyres you will only mask the real issue.

Would it be ok for him to check them all at the same time or does he really have to wait till 3,6,9 and 12 oclock?shorty_f0rty wrote:if thats not it check your wheel bearings..

Nah seriously, all the advice mentioned here is pretty good so do it and let us know how you went.
