Here is the scoop. 1996 X90 power steering box was leaking a little around the adjusting screw on top when I bought it a a month or so ago. I put some Lucas fix in it and the leak slowed to almost nothing in a few days. Weather turning cold now in PA and steering is becoming stiff until it warms up. Now it has belched out some fluid from the reservoir a few times. Should I be looking at replacing or rebuilding the gearbox or is this a sign of a different problem?

sounds like too much Lucas, you might want to
drain the system and refill with new fluid, synthetic ATF from
Royal Purple should work well

Yea, kinda makes sense. I'll try it and see what happens.
