It is possible the tie rods are too tight, especially if the bushings are shot. I'm not 100% familiar with that machine but a lot of the models need the tie rod nut run up pretty snug then a cotter pin through the castle nut & tie rod to keep it from backing off?
If you torqued them down to specs, you should be good. 40lbs isn't that much. If it has been ridden a lot, you would have a little slop. New bearings and re-torque of front end should have tightened things up. If it's just a little tighter, that's good. If it's flat out hard to turn, there may be an issue.
