I've got a vibration in my steering wheel from 80+ apparently it's a common occurrence in vehicles with disc fronts and drum rears. Apparently means the breaks need to be shimmed, might be the same issue ?
I used to think this also, and i tried getting rid of it by getting balances and alignments etc done, it never went away, so i just lived with it thinking it was just a triton characteristic.
Well i can tell you, its not , i got my suspension done last week by ultimate in SYD and i can confirm that all wobble and play in the steering has disappeared. Could not be happier
