HI GUYS, around a month ago i noticed a steering wheel shake at around 40-65 and my car didnt feel right at all so at first i thought wheel balance! had that done no difference. then i had new ball joints/steering damper and steering colum bushes as this was advisories on the last m.o.t so i wasnt to bothered about that and the car drive is very much improved{much nicer steering etc. but still i get a slight vibration in the steering wheel at 40-65 not all the time but most! so i started blaming the aftermarket wheels but ive had them on 6 months and im sure it was ok before last month!! ive been back to have the wheels balanced but the guy reckons its the aftermarket wheels, i can understand what hes saying but like i said they were fine up until last month. it brakes fine no wobble and drives straight and true! does anyone have any ideas as its really annoying me now as my car would be perfect except this. any advice much appreciated. like i say it is much better but not perfect im wondering could it be tyre pressure etc?? i carnt see any point in going back to get the wheels balanced again although on other posts this is what people are saying?? is it worth goin to another tyre place to get them balanced again??? many thanks in advance
