You should use the utilities provided by gazebo to debug your problem.

The tutorials are a great place to start.

You can also visualize joints, inertia, collisions in the GUI.

thats fine i think we were actually running the same model which i built with ros indigo and hence with gazebo 2.2 Now we have switched to ros kinetic and hence gazebo 7 some of the gazebo api's like set max force have been deprecated and hence there is no way to set max force now, thats why i think the front wheels tend to drag out a lot.

is there any fix?

What are the limits for the front wheel joints? have you configured them? Because if you don't, they won't rotate at all.
