My 2002 has recently started shimmying on the Right Front wheel. It does this from a range of 25-45. The odd thing is it doesn't always do this, it just picks when it wants to do this. When I press the brake it is more pronounced. Also at higher speeds the alignment seems to be off and not always consistent. The only thing I can think of was I had to have a post for one of the lug nuts replaced recently, it is possible that something was removed and improperly reinstalled. Any advice would be appreciated.
