The dealer that did the frame
The dealer that did the frame replacement on my '05 Tacoma SR5 4X4 is Summit Toyota in Akron, Ohio. The work was well done and finished on time.
I do most of my own work too. Last November I was doing a brake job and it scared the heck out of me to see how rotted out the frame had become. There is absolutely no question in my mind that the frame didn't have long to live and that frame replacement was totally worth doing.
Yes, the dealer did try to upsell me with repairs, most of which were unnecessary or I could easily do myself at the appropriate service interval. I told them to just do the best they could and if they were to break anything, to take it up with Toyota. The frame kit comes with a large number of new parts, such as two new leaf spring packs and many new brake lines and fittings.
I think many large dealers have done a lot of frames by now, so probably learning experience has gotten them past a lot of the horror stories that have been reported. I am very pleased with the quality of work that was done on my truck. It is still less than a month, but I have been keeping any eye out for any any loose bolts or other stuff out of whack. No problems yet. I had the dealer rebleed the brakes after a few days of driving. The pedal feel seemed a touch soft and the rebleed seems to have firmed up the pedal feel to what I expect.
