How to make your blazer drive better?

[LuckyScott]

I have a 72 Blazer that is lifted with big off road tires. It wanders a lot going down the road. So I replaced the steering box and the power steering pump and made it better. But it is still not as good as I would like.
I read a thread about a guy replacing his steering box and someone posted this........

"I hope that the steering box will solve your on highway driving. I changed mine with no difference checked balls everything come to find out rear springs were rocking back and forth. Spring pads were misaligned so i aliened the pads solved the problem. Good luck"

That made me think where to look next to try to improve the steering and make it easier to drive.

Any suggestions?
