99' Sport steering and making noise under acceleration

[452films]

Have a 99' Sport 4.0 OHV and when I got it the tranny shifted like crap. Did a filter change and added lucas and slowly worked in and now shifts like new. I can accelerate up to highway speeds ( 75+ ) if I do it a slow pace ( keeping RPM's under 2500, and sometimes as high as 3200 ). I know I have a sticking caliper and need front rotors, but dont think this would cause a problem. If I try accelerating faster than that the car starts to make a howling noise and the steering wheel will pull to the left for a second. Any ideas as to what this could be? This is in Auto4w not in 4WD hi or low.

No one? It goes away sometimes, but is more than usually there.

Come on! I need to figure this out. 1200+ miles and still does it
