[john charlton]

I had sudden severe wobble at about 20 MPH . I pulled over but could not find anything obvious .I drove home at a sedate speed but no recurrence . I jacked up the front to check all front end components and the wheels . I spun the wheels to check for buckle and tyre bulges but all was fine . I noticed that one wheel stopped at the same spot every time very strongly .My local tyre shop had a ballancing machine that could ballance a 19" wire wheel and found the wheel was way out of balance by about 8 ounces .The ballance weights were clipped on the rim (both sides) .I had the other wheel done as well but was only slightly off ballance .The wobble has never returned ,I think both wheels got in synchrony at one critical point which produced the sudden onset . I have another car with a very mild wobble so I swapped the fronts for the back and fixed that but I supose they ought to be ballanced . The 21" wheel can be ballanced with the stick on weights used on alloy wheels .
