Abstract: A tube yoke member and method of forming the tube yoke member. The method includes providing a tube blank and a mould having inner surfaces with a per- determined shape. The tube blank is then hydro-formed into a hydro-formed member with a pre-determined shape conforming to the inner surface of the mould. During the hydro-forming process, an amount of force is applied by a first and second actuator assembly attached to a first and second end portion of the tube blank. A first and second tube yoke member having a substantially tubular portion and a hydro-formed portion are then separated from the hydro-formed member. A first and second yoke arm opening is then formed in the first and second yoke arms of the first tube yoke member and a first and second yoke arm opening is then formed in the first and second yoke arms in the second tube yoke member.
