i havent personaly had this problem my freind though has me being the more able one when coming to sorting niggles marked where the wheels were sitting on my garage floor with a chalk line then measuring the distance of the space between the alignment cut some steel tube out of the same size as the axle or whatever you want to call the bolt going through the wheel) cut it to the right length and replace the original spacers the result was good but temorary as i didnt smooth the edges which damaged the bearings but smooth it and it should work at treat
