Disclosed are a bending roller apparatus and methods for use thereof for repairing a control arm of automotive suspension. An example apparatus includes a base having a saddle supporting a matrix to which the control arm is removably affixed. The matrix provides longitudinal and lateral movements and rotation of the control arm in a horizontal plane. The apparatus includes a matrix position calibration means for calibrating longitudinal, lateral and rotary positions of the matrix. The apparatus includes a bending roller positioning means for calibrating vertical and longitudinal positions of a bending roller to bring the bending roller in a contact with the upward-extending flange. The apparatus further includes bending roller means for bending the upward-extending flange inwards by rolling the bending roller along the circumference of the flange while applying a downward force on the flange thereby bending it inwards and sealing off the ball stud in the receptacle.

1. A method for repairing a control arm of the automotive suspension using a bending roller apparatus, wherein the control arm of the automotive suspension includes a body having a receptacle at one end thereof, and a ball stud having a ball end inserted in the receptacle, the receptacle further including a substantially continuous circular, upward-extending flange welded at an edge of receptacle, the method comprising: affixing the control arm to a matrix of the bending roller apparatus, wherein the matrix provides longitudinal and lateral movements and rotation of the control arm affixed thereto in a horizontal plane relative to a base of the bending roller apparatus;calibrating longitudinal, lateral and rotary positions of the matrix of the bending roller apparatus in the horizontal plane relative to the base of the of the bending roller apparatus;calibrating vertical and longitudinal positions of a bending roller of the bending roller apparatus to bring the bending roller in contact with the flange of the control arm; andbending the upward-extending flange inwards by rolling the bending roller along the circumference of the flange while applying a downward force on the flange thereby bending the flange inwards and sealing off the ball end of the ball stud in the receptacle. 2. The method of claim 1, wherein prior to affixing the control arm to the matrix: determining a type or configuration of the control arm of the automotive suspension; andselecting out of a plurality of different matrices, a matrix associated with the determined type or configuration of the control arm of the automotive suspension. 3. The method of claim 2, wherein calibrating positions of the matrix and positions of the bending roller includes calibrating using a plurality of electro-mechanical actuators. 4. The method of claim 1, further comprising controlling the electro-mechanical actuators using a computer operable to execute an algorithm for calibrating the position of the matrix and the bending roller for different types of control arms. 5. The method of claim 1, wherein calibrating positions of the matrix and positions of the bending roller includes calibrating using manual control means. 6. The method of claim 1, wherein the matrix comprises at least three stacked plates slidably connected to each other, wherein the bottom plate is rotatably connected to the saddle of the base, the middle plate is laterally slidable relative to the bottom plate, and the top plate is longitudinally slidable relative to the middle plate, and wherein the top plate includes means for removably affixing different types of control arms of automotive suspensions. 7. The method of claim 1, wherein the control arm, including the receptacle and the flange, are made of aluminum or aluminum alloy, and the ball stud is made of steel.
