I have a 1984 Toyota hilux 4X4....and I have a lot of slack in the steering.....I was looking on the gear box and I didn't see any way of taking out the slack....there is a nut on top of the gear box when your looking down.....but to me it looks as if its just some kind of vent.....I would of thought that it would of been a lock nut with a screw in the middle....but its a vent right now.....so I wanted to see if this piece was broke off prior to me buying it or is this the way that it comes.........and if so is there anyway to take the slack out of the steering.....Thanks
