driving in a straight line

[Mo_Bedda]

OK, here goes nothing. I thought since I just got this new project I would post here before starting to replace parts to fix this issue. I have a blazer I just got it has 33x14.5x15 tires on it the front end looks fine I checked the ball joints, steering box, sway bar bushings and for the life of me can't get this thing to drive in a straight line I have to constanly have to correct and over correct to get this action to happen - anyone have any idea's. any info would be most helpful.

Cheers

have you taken it to an alignment shop and had it aligned?

Might have a cracked frame at the steering box...also having tires that wide doesn't help

Check the pitman arm to make sure it's tight on the steering box. My steering is pretty tight since I found out that's what the problem was.
