How's Your Steering Ratio?

[adpostel]

I have noticed that my truck turns alot tighter to the left than to the right. The other day I was going around the block, and I almost couldn't even turn right out onto the street without hitting the curb across the street. I almost had to back up and straighten her out. I know the PO replaced most of the front end from an 84-86ish truck. Is this normal, or is something not right here? Shouldn't it turn equal amounts both ways?
