I got the lifetime alignment at Firestone. It is a pain to get them to do it right though. It's amazing how many alignment guys can't do alignments. Out of 6 Firestone's, only one has the a guy, who happens to be the trainer, that can do an alignment properly.

Anyway, last time I checked it wasn't just as easy as changing my oil to switch out the bushings. I was able to get the zerks on and it definitely solved the problem. At least now I can lube them properly. I do have the black bushings too. I tried the Tri Flo but it didn't do any good. I wonder if the alignment guy over tightened the adjustment bolts and that is what caused the lube to get squeezed out. The squeaking did start right after the last alignment....makes sense but either way Calmini should just install zerks from the beginning period!

By the way, I'm just as hard on my truck as anyone else. We won't all have the exact same problems. Each truck is different. I think i'm going to remove the bushings and re-grease on the shackles tomorrow. I've been in such an industious mode lately.
