After the glue has cooled (20 minutes would be good) roll the axle on the ground and work with it to get it straight. Squeeze the wheel at the axle when adjusting the wheel. The wheel can rip off the axle if you don’t handle it carefully.

Make these 3 little cuts and bends on the body of your car.

Glue the straws to the body… keep the axle out of the glue.

Cut two supports for the axle straws.

Put plenty of glue under it. Keep the glue off the metal part of the axle.

Add glue on the outside too. This part of the car will be under considerable stress.
