An adjustable wheel bracket assembly which includes a relatively stiff wheel axle crank and a relatively flexible spring steel adjusting lever keyed to the crank is provided with tension producing mechanism to take up the tolerance and eliminate play in the assembly. The tension producing mechanism comprises a warp formed in the spring steel lever and a clamp to exert pressure on the warp and thus create tension in the system to hold the assembly together without play.
