I have a 40' Scarab with 502's and TRS drives. my steering is very loose as in I can turn the wheel one way and it reacts instantly but to turn back it does not and don't know what to start looking for. Wondering if anyone can guide me as what to look at first or has ever heard this before.

Look at your swivel pins at the top of the gimbal were the steering arm attaches there were out all the time. Best bet is to convert to full hyd steering.
