Pic. 4.32. Scheme of operation of the turnbuckle of the toe-in adjustment mechanism: 1 - front part; 2 - with left-hand thread; 3 - with right-hand thread; 4 - adjusting rod; 5 - from the side of the axis; 6 - for discrepancy; 7 - for convergence
When the adjusting rod is rotated, the amount of convergence changes. One turn of the rod changes the toe by approximately 0°43' (pic. 4.32).
