I have the standard SRI alloys with four brand new Michelin Primacy tyres fitted, ive changed wheels back to front side to side introduced the spare, changed all suspension componants / steering joints,replaced front and rear discs and pads with GM parts ,had all wheels balanced several times on various machines, the last two being the all new fancy Hunter gsp9700,all wheels checked for buckles etc. one wheel does have 40g of weights, this is on the rear offside, the rest have 5g upto 10g. Four wheel alignment etc,etc and still get a very slight vibration through the steering wheel at 80mph only, all other speeds no vibration? The vibration varies on different road surfaces and more noticable after traveling a good number of miles on a motorway, which led me to believe the vibration was heat related ie the discs or tyres, hence the replacement of new parts, but to no avail notsure.gif
I hope you sort the problem :wtf:
