Thanks for the replies. After a day of changing wheels round, driving around... Again and again with different combinations. I seem to have sorted it. Checking all the wheels... it seems that 2 wheels are not true. Ie buckled for want of a better phrase! The joys of cheap steel rims... After over 7500km something tells me Chevy won't be so forth coming in replacing said wheels under warranty... I will be getting the tie rod ends checked with the dealership as well. Thanks Gearhead and Skids.

7500km on the clock, just started taking it to 120kph and get wobble intermittently. Had both fronts balanced and still happening intermittently. Concerned could be drive shaft? Not hit anything run over anything tyres are ok. Any ideas??
