This Issue is caused by out-of-round tires. They roadforced them and found that the stock Michs' each have a certain amount of out-of-roundness (they very were surprised by the results). Put the two best on the front and there is no shimmy. Dealer made print-outs of the roadforce charts and are purusing two repalcement tires from Michelin.

I give the service department at LAND ROVER HARRISBURG 100% props!
