Pulls to the right.
 

This winter I had all four balljoints,all wheel bearings, 4 new goodyears and new rotors-pads installed on all four wheels. Then of course I had it aligned. I noticed it pulled to the right. Not bad, but bad enough for the amount of money and time I have in my 2001 blazer. So of course I took it back and had the alignment checked. It was dead on. I have been driving it like this for 6 months now, no odd tire wear. I would like to get this fixed so I can cross it off my to do list. My thought is control arm bushings. Has anybody had a similar problem? What was the fix? Thanx

Was it the same place who aligned it the first time? They might not want to admitt a mistake. Or, it could also be the idler arm.

+1 or a tie rod end, upper &/or lower control arm bushings. Drive it for 15 mins or so then pull over & put your hand on the center of the rims. If one side is hotter than the other possibly a wheel bearing was over tightened or the brakes weren't bled properly.
Is it 4 wheel drive? If so it might be a CV joint on it's way out.

it could also be the tire pressure check that
