How difficult do you think it will be to get the dealership to do the tsb on my 05 dc prerunner, i do have a GREAT dealership near me but the problem is i lifted it 2 months ago and installed toytec aal's. i know that the kit i have was for veh w/o the tsb done. I do not have a rough ride the only prob i do have is ive noticed that when i did the lift my truck was level well 6k miles later rear has sunk down. i will contact toytec if i have to and ask about swapping parts doubt that will happen. also considered installing a 1" block i hate to do that but its very annoying the way it sits.
