Front End Help

I was getting a clunking noise out of front end, looked like a bad swaybar link or sway bar. Changed them both and turns out the links and bar were fine, rather the links were hitting the subframe. Looked like whole thing was shifted towards the passenger side. Turns out axle had shifted because the track bar nuts were loose and everything shifted that way. So, yesterday I took to alignment shop centered wheel and everything was great. Today I poked my head back under to show my buddy how the links were now even and low and behold they were shifted back towards the passenger side. WHAT THE F#$%. The guy at the alignment shop says to bring it back and he will look at it. Any ideas?

did the alignment shop actuailly replace anything, or did they just tighten everything?
have someone sit in the truck and turn the steering wheel from side to side, wile you (or the guy at the alignment shop) look at the linkages under the front end. you should be able to tell where the problem is, because anything that is worn will have play in it that will be visable wile the steering wheel is being turned.
my guess however would be that either the ball joint (frame end) or bushing (axle end) of the trackbar are bad. in most cases it's the ball joint that goes bad first, but having a bad end on either end of the track bar will let the axle shift to the side like you described.
good luck

Brand new track bar.

Brand new track bar.

I just read your post and was gonna guess track bar, I've replaced several of those over the years.
