Im getting this error :Assets\Scripts\Car.cs(32,32): error CS1061: ‘WheelCollider’ does not contain a definition for ‘position’ and no accessible extension method ‘position’ accepting a first argument of type ‘WheelCollider’ could be found (are you missing a using directive or an assembly reference?)

Assets\Scripts\Car.cs(33,32): error CS1061: ‘WheelCollider’ does not contain a definition for ‘rotation’ and no accessible extension method ‘rotation’ accepting a first argument of type ‘WheelCollider’ could be found (are you missing a using directive or an assembly reference?)

Can i Get some help please

public class Car : MonoBehaviour
{
    public WheelCollider wheelColliderLeftFront;   
    public WheelCollider wheelColliderRightFront;   
    public WheelCollider wheelColliderLeftBack;   
    public WheelCollider wheelColliderRightBack;

    public Transform wheelLeftFront;
    public Transform wheelRightFront;
    public Transform wheelLeftBack;
    public Transform wheelRightBack;

    public float motorTorque = 100f;
    public float maxSteer = 20f;

    void FixedUpdate()
    {
        wheelColliderLeftBack.motorTorque = Input.GetAxis("Vertical") * motorTorque;
        wheelColliderRightBack.motorTorque = Input.GetAxis("Vertical") * motorTorque;
    }

    void Update()
    {
        var pos = Vector3.zero;
        var rot = Quaternion.identity;

        wheelColliderLeftFront.GetWorldPose(out pos, out rot);
        wheelColliderLeftFront.position = pos;
        wheelColliderLeftFront.rotation = rot;

        wheelColliderRightFront.GetWorldPose(out pos, out rot);
        wheelColliderRightFront.position = pos;
        wheelColliderRightFront.rotation = rot * Quaternion.Euler(0, 180, 0);

        wheelColliderLeftBack.GetWorldPose(out pos, out rot);
        wheelColliderLeftBack.position = pos;
        wheelColliderLeftBack.rotation = rot;

        wheelColliderRightBack.GetWorldPose(out pos, out rot);
        wheelColliderRightBack.position = pos;
        wheelColliderRightBack.rotation = rot * Quaternion.Euler(0, 180, 0);
    }
}

You need wheelColliderLeftFront.transform.position etc…
