*DISCLAIMER* I haven't even looked at the steering box on the VX, but I'm assuming its the recirculating ball setup we have on the troopers.

If you look down at the power steering box, you'll see 4 bolts with a flathead screwhead and nut in the middle of those 4 bolts.

Its helpful to hit the whole thing with some PB Blaster about a day before you try this. Get a flat head screw driver and hold that center screw in place while you break the nut free. It wont be easy more than likely.

Once the nut is free, turn the screw clockwise to tighten up the steering play. Use SMALL adjustments, less than 1/4 turns, it wont take much.

Once you have it where you need it, tighten the lock nut down again. Probably wouldn't hurt to use some mild (blue) thread locker on it to hold it in place.

Again these instructions are based on the steering box in the troopers. If it isn't the same then I'm sorry.
