My advice to everyone is to get a copy of the alignment results the dealership does.They said they did the alignment and reprogram called for in the TSB, but I can only take their word for it as they did not note it on the ticket.
I just had the TSB done 2 weeks ago - and I had posted my experience elsewhere - the thing is - it's better at slow speed, but still loose on the highway etc.
I posted a copy of my alignment from the dealership in that thread and (I'm not familiar with this) someone pointed out right away that my caster is way too low for my 3.5" lift [caster at ~3.6] and would definitely be causing me to have loose steering.
I showed this to the shop that did my lift (and they outsource an alignment after that) and agreed the outsourced shop didn't compensate the caster for the lift properly and that should be why my steering is still loose.
I'm having my caster adjusted in a few days becasue of this - and per this forum, and the lift shop - that should tighten up my steering.
