Truck Alignment keeps getting out of whack. Is this normal? - Pics

[toddtime]

Truck is a 2003 GMC Sierra 4x4. It started about a month ago when I took my truck to Firestone for an alignment. They aligned it and it stayed aligned for a couple days till I noticed the steering wheel started to be off center when tracking straight. It slowly got worse and worse until the steering wheel got to the point where it was 30* right of center when tracking straight. Going over bumps or any kind of undulation in the road caused the truck to pull hard to either side. I got under the truck and noticed this in the picture.

That is the driver side, passenger side nut is tightened securely against that sleeve.

I took it back to them under warranty, and they realigned it. Again, it stayed aligned for a couple days, then eventually same symptoms as before.

Is there anything that has wore out in the front suspension causing this reoccurring problem? I wanted to get some advice before I take it back again or start throwing money for parts. Thanks!

If the jam nut loosened again, The guy doing alignments needs to "man-up" & tighten it!

i agree with clinebarger, im a full time alignment tech and if thoes jam nuts keep backing off then there not getting tight enough, but just to be safe have them pull the outer tie rod off and check the threads for rust and corosion before they re-align it
