My g/f was complaining about a shaking and wobbleing in her steering wheel last week one day, i think it was actually a day after the snow we got on saturday....but regardless, the way she explained it (on her stock 98 xj) sounded to me like an out of balance wheel. Now the only problem was come time for me to drive it, it went away and she agreed. Now yesterday we went into an unplowed parking lot i tought her how to do some drifting and what not, then on the way home we felt it again. When we got home, we decided to put the spair tire on...and change eventually all four until it went away to prove it is an unbalanced wheel...thats when i noticed there was snow packed in between the spokes of the 5 spoke "classic" wheel. So we stopped b/c it was so cold and thats what i told her musta been doing it. Mainly b/c i didnt think a tire can unbalance and re-balance on its own so the fact it went away for a week had me thinking. Could the snow have been the problem?? This was just last nite so i dont know if she drove yet. Thanks for any thoughts.
