the different years vary a bit
I take an allen wrench and a long peice of steel round stock .. drill a hole in the roundstock ,nsert the allen smack roundstock wth a hammer to lock the allen in there
this gives you a nice long reach and will save some skin ,, then you will either have 1 or two retaining nuts on the top of the box ,, loosen both turning the wrench cc as looking down from the top ,
now with those loose you take the allen and tighten the screw clockwise as looking down on it ,, the trick is you also need to hold the last nut you lossened otherwise it will lock everything up again
you may want to jack a 2x4 in the inner fender well and also wear gloves ?
tighten that center adjuster and keep rocking the steering shaft back and forth till the play is minimized ,, you must test drive and tighten .. this makes sure you don't overtighten and bind it all up ,, it still needs to return to center when you let of the wheel moving forward ,, when test driving just tighten the bottom nut if you have 2
