Glad to see you are on the road. If it the box looks tight it probably is ok. To adjust it loosen the big nut and turn the inside screw until you can feel the recirculating balls start to tighten, then back off a little bit. Can't help on other suspension issues or the AC either, if the low side is leaking that is probably the cause. The front discs do most of the work anyway, but if it bugs you an adjustable proportioning valve will let you balance front to back.
