Steering issues 97 DCS

[notsobadbotbuggy]

My 1997 DCS cart has developed an issue with the steering mechanism where it will not turn to the left unless the cart is moving. If you attempt to turn the wheel with the cart sitting still, there is an audible stripping noise from the gear assembly and the wheels begin to turn then snap back to the original position. Are there any options of rebuilding the steering box assembly or is it better to bite the bullet and purchase a new one? If the latter, I'm open for suggestions on who has the best deals as the ones I've found on ebay are north of $300. Thanks in advance
