This van started out as a 4x2, but was upgraded to a 4x4.  A donor front axle was added to complete the conversion.  This is where the crew at TW came into play.... the big rig wonders on the road when driving over 40mph.    What could they do to help it out?  They rebuild the drag link, upgraded to heavy duty shocks, added a damping shock and bought new load E tires.  This rig now cruises at 80 mph straight as an arrow.
