need the help of mopar/suspension gurus!

ok here is what I have. I just bought a 72 duster 440. it had a leaking power steering box. I jacked it up, replaced the box and then decided to change out all of the bushings in the upper and lower arms, and all the tie rod ends, while I had it in the air. once that was done, I knew I was going to be way off on the alignment so I took it to the local alignment shop. on the way there, the tires were howling so bad I had pull over to make sure it was gonna make it. anyways, I get there, he aligns it, and I took it home. seemed fine on the way back (steering was a little loose) but no howling. parked it in the garage while I did some dash and engine compartment restoration. took it out to drive it today and again the howling is back. the steering seems to be grabbing and I don't feel like I have a lot of control of it. I can also smell the tires burning. make it back home and I can see the obvious toe in and the front ends seems to riding higher. I start it, turn the wheel back and forth and the front ends lowers and the toe in is not as bad. I measured the height at that time and was 26 inches on pass side and 26 1/2 on the other. drove it again and half way down the road, same thing....tires howling, burning, and get back to find the front end is 1 1/4 inch higher again.... what is going on???? HELP PLEASE!
