i am doing up a dexta, the steering is quite bad , when its on the road with a bit of speed the wheels are wobbling like a mad thing, and its not felt in the steering ,there is huge play in the steering , both wheels wobble like crazy , i opened up the the top steering nut the other day to see what can be replaced or not , i found the top nut , it was not wound all the way down on the worm , when i did turn all the way down i couldnt fit back the steering wheel, it was miles away from it.
what are shims, i hear people talking about them , i thought they were a spacer of some sort.
where most likely is my problem and how do i fix it ,
in lay mans terms would be really appreciated
