My 01 chevy 1500 van has developed some looseness over the last 10k miles ( van has 150K miles). It wanders a bit and lacks the responsiveness it used to have.

Its not too bad, but I have just replaced the engine and trans, and now everything is perfect except the steering and handling. Its diving me nuts.

Where should I look first, what areas are suspect on a chevy steering system?
Its a recirculating steering box system-not rack and pinion.

Another problem, possibly related, is that the van is pulling left while driving, and pulling hard left when I break. again... where should I look first?

The steer tires are new.
I know this is very vague, but I'm hoping you chevy guys know where
to look first.
Thanks Hotrodders!
