I put a redhead gearbox in my truck back in April/May . I’ve been hunting down play in my steering . I can turn my steering wheel from 11-2 without it doing anything . It’s just dead space . I have new wheel bearings , pitman arm , and tie rods . There is the same amount of play whether the truck is turned on or off . I crawled underneath and grabbed the steering shaft with my hand . The truck was turned off and the steering shaft turned back and forth . That’s where the play ends . Does this mean it’s my new gearbox ? Should that steering shaft be tight if the truck is turned off ?
