Steering Gas Powered Rover (900 lbs)

Hi, I am currently in the early stages of trying to automated my Club Car Carryall but have reservations about how to steer the machine. I’m thinking a 2000 ozin servo to push in pull the tie rod. This servo would be mounted to the frame. Does anyone have any experience with moving these vehicles that do not have power steering? My current worry is that I cannot find a servo strong enough as it takes quite a bit of force by hand.

Also, if anyone has experience powering the servos and pixhawk using the car battery within the vehicle would be helpful as I have not looked into it too much.

I would explore a large format 360° servo geared to the steering shaft.
