assuming that your front end is all good, tie rod ends and ball joints etc, the 2 inch play in the steering is not the power steering box as it has a solid shaft going through the box. the play that develops is on the lower steering post where it splines to the lower portion of the ps shaft. i had the same trouble with loose steering and now my steering is tighter than a new 850. just pull it apart and drill and tap some knurled ended set screws into the lower steering post to lock the splines together, red locktite on the screws. there is a thread on the forum somewhere that has pics to explain this. this lower steering post takes most of the brunt from the anti kickback steering. search play in eps box. I have 500 km on my machine since i added these set bolts and steering is still tighter than a new xp, you couldn't have tighter steering. im in alberta canada and we ride the roughest mountain trails we can find. this is a really good test for these set bolts and they work perfect and take a beating. Theres nothing like having lunch at 8000 ft, although even brand new machines have troubles at this elevation running properly.
