'96 Chev Blazer 4wd, driving at 50 - 60 mph front end seems to sway. vehicle has all new parts in front end.

Answer 1

Two things it can be that comes to mind. One: the front end is not right. Either it is out of alignment, the ball joints are shot, a bad Idler/pitman arm, or tie rod end. In other words something is not right with the parts or the alignment. Second: The Air dam is missing out from under the front of the vehicle, and it is loosing the down force from it. I have a blazer 4WD and once when I was working on it, I took it for a test drive without the air dam on it, and it drove just like that. Most people are going to say the dam is there for cooling purposes and doesn't have anything to do with the steering, but I'm just telling you what happened to me.
Oh yeah, you might try rotating the tires to see if that makes a difference, and to rule out it being the tires.
I hope this helps. Good Luck!!!
Part 2:
Some people just go down the line marking good answers as bad ones. You have two certified mechanics that give you the answers that make sense. Why someone has to do this is beyond me. They are after points and do this with total disregard to the real best answers.

Answer 2

i own a repair shop,and it could be in the alignment,,i know it was just done but it could be off a few degrees,,it only takes a small pot hole to knock one out of alignment,,there really easy to knock out,,but you might want to take it back to who ever aligned it,,and have them check it,,tell them its not driving right,,and also check the tires on it,,they may have wore to the old pattern of the front end this will cause it to do that also,,i been at this for 36 yrs,,and i have seen bad tires on new cars ,and it made them drive bad,,good luck i hope this help,s.

Answer 3

i agree with dodge man but also if you have oversize tires like the optional size for that blazer that might also cause it to sway

Answer 4

Did you have a proper alignment done?
