I too have a 1992 Tracker 4x4 with a 4 spd trans. I have towed this vehicle all 4 down for a number of years at all speeds, including sustained 70 MPH Insterstate travel with no prob;ems whatsoever. Just make sure the steering is not locked, the transfer case in neutral and the hubs in freewheel. email me with any questions. pluhars@sbcglobal.net
