Did you bolt it together the "fordfasterr" way or the way I did with my first one? I am guessing you did it "my way" since you talk about the bearrings. Remember when you use the triangels axle as a bolt to connect the bikes dropouts to the triangle you must remember that the two axel pieces is not the same lenght. that way the rear wheel is not right behind the front wheel. Could that be the problem?

Also the added bar (steel flatbar?) need to be properly in place. I like to use a "square tube" from a car`s roof rack. Easyer to do a good job with that one in my opinion.
