i have 2 terra tigers. one runner and one basket case, and just sold my other project machine. the belt from the engine drives the jack shaft. from there you have 2 steering clutches/ brakes that disengage the jack shaft on one side or the other. you probably need to replace the clutches, but the jack shaft could just be out of adjustment. if you PM your e-mail addresse i can send you a copy of the owners and service manuals. the jack shaft adjustment is a pain in the butt
hope that helps
