3. 2.3 Adjust nut -2-  turn clockwise = vehicle higher/turn anti-clockwise = vehicle lower.
4. 2.4 Lower the vehicle onto its wheels (remove pit lifter).
5. 2.5 Compress (pull down) the vehicle once and allow it to spring back freely. Then check the vehicle height and wheel loads.
6. 2.6 After you have adjusted the lock nut(s) -1-  on the front and rear axle, tighten with special tool > 9647 - hook wrench  together with a torque wrench.
