I need some help on this one. Did some forum searches and did not really come up with anything. Anyway, I have two TB's one an EXT LT, the other a SWB LTZ. Last year I lowered the EXT on Ground Force springs and there was a horrible creaking noise while making tight turns. Almost sounds like something is binding. After about three weeks and letting the springs settle, I bring it in for an alignment. They couldn't get it to align perfectly to factory specs, but close enough. The sound goes away and has never returned. A few months ago, I lower my SWB LTZ on Eibachs. No front end noise whatsoever while making tight turns. I again wait about three weeks for the springs to settle and bring it in for an alignment (during this time there is no noise). After driving around for a week or two after the alignment, that horrible noise is present while making tight turns in my SWB now. Is this something related to the alignment. I can only assume, being that I have no idea what is involved in performing an alignment or what is adjusted/adjustable. Any one with similar experience or knowledgeable in alignments, particularly with the 360 platform want to chime in and confirm my hunch before I bring it back to the alignment shop and start any accusations?
