Question

[62 short step]

If one of the front leaf spring was sagging, would it affect how it goes down the road? My truck has been to the alignment shop and they set the toe, and its still pulling to the right. The leaf thats sagging is on the drivers side of truck. Thanks for any help.

I don't think that a sagging leaf spring would cause it to pull. You may have a tire that is separating or brake that is hanging up. Also front wheel bearing preload my not be set right or a bad bearing. This sounds dumb but make sure tire pressures are the same. To check for a tire separation that you can't see swap the front tires if it pulls to the left you have a tire that is bad or rotate tires front to the back if the pull goes away you have a bad tire. Also a broke leaf spring center bolt or a spring pin and bushing at the front of the spring worn out may cause a pull. I hope this helps.

Thanks Gilbert, I will check all of this again. I will also rotate the tires.

I think that 66Gilbert has it pretty well covered. Don't ignore the rear though, if you don't find anything obvious in the front. A dragging rear brake can cause it too.
