I have the same 4" trail master lift, that was installed on my rig after it was in a head on where the right frame was bent(repaired at a frame shop, but still not oem), I run 33's and I don't have a problem having it aligned, and I use all oem length parts. Fortunately for me my buddy was a front end mechanic(now is in management) when ever I come across a tech that says it can't be aligned, I give my buddy a call and hand the tech the phone.
I would give a few other shops a call, and see if they have any real front end mechanics, not just certified techs who can't think beyond what the machine states. If nothing is bent there shouldn't be any reason why the tie-rod end need any machining, and a real mechanic wouldn't have suggested it.
What size tires are you running, are the t-bars at stock setting?
