i get it, hold wheel its fine, let go of wheel between 50-80 whobbles like crazy, its not dangerous. had my wheels rebalance, swapped fronts with rears, new lower arms, new steering bushes, ploy brushed all round, i guess its just part of an old car, i can live with it.
bit like living with it ages to fill up at the petrol pump cause it keeps clicking if it goes in too fast, the fun and frustration of owning an old car
