Hi Simon
If you have the box on the bench, try the adjustments and see if you can get it somewhere near where you want it.
(Adjustments: endfloat on the worm, endfloat on the drop arm, meshing of the gears, starting point on the worm (maybe). See manuals and the Forum for details)
That means adjust it until there is still just free movement at each end of the travel required - no stiffness is allowable - and then see what you get in the middle.
Quite a lot of play - one to one and a half inches - is normal. This makes steering a car that tends to steer itself even more interesting.
Try all three sectors of the worm. Work out where the drop arm swings fore and aft when the box is in the car, then rotate the whole thing 120 degrees and try the next sector, repeat for the third.
DO NOT, yet, think about taking the gear off and moving it. It is not easy, and usually (in my case anyway) involves quite a lot of damage to components and an annoying amount of rectification. And I am very good at taking things apart without spoiling them.
If one sector really is better than any other, then come back for advice about removing the gear. Better, get someone who knows what they are doing to do it for you.
If the free play is too much, and the sectors all about the same, then you are into finding a replacement, or grinding as previously mentioned.
Cheers
