Hi Guys! Sorry for boring you guys with another TSB post. After two weeks of effect, I finally got my rear suspension TSB done today -- couldn't have done it without you guys' help, espacially Mr. BUK 0H5.
Let me say the positive things first. The rear suspension is a lot tougher and he handling is better. The ride is not much worse. Overall I love the results. Surprisingly the rear lift for mine is only 1/2" (37" to 37.5"), as oppose to the other cases I've read which are mostly 1" to 1.5" lift.
Now the but... But the dealer didn't do a re-alignment afte installing the new leaf springs. They did a "Basic 9 point inspection" instead. I asked and they told me the tech drove the truck around and found no sign of mis-alignment. I spoke to the service director and she told me that her Toyota rep. told her no alginment is needed if only leaf speings are replaced. Only non-TRDs with the shock upgrade will received the alignment. I pointed out the TSB and they said TSB does not applied to 09s... Can you actually believe that?
I did search and find FL4x4Taco had the same problem. So maybe you can shed some light on this too. Thanks in advance man!
OK, enough bitching for now... I would like to ask the truck/alignment Gurus here a few postive questions with the goal being to solve the problem and get some peace of mind:
1. What is the reason behind the alignment? Some posts said it is the rear lift causing frond wheels sitting at the different angle. But is it true that the lift will eventually settle? In my case, the lift is small. Does it justify no alignment?
2. Why does TSB re-state the alginment specs? Does this mean the specs changed after the TSB? Also, the specs are really loose. For example, for Prerunner TRD OR, the range is 0.099 +/- 0.108...
3. Can a experienced tech tell whether a truck is in- or out- of-alignment by just driving it? How will I know if my truck is out of alignment during daily driving other than measuring the tire thread depths every other week? Mine is not pulling right or left. Is the uneven tire wearing the biggest concern here?
I know this is boring and too many questions... But please please it bothers me ... If I just want to pay another dealer to do the alignment, you know, pay small money and get peace of mind, shall I give them the TSB as a reference too?
I will post some before and after pictures but I doubt the difference is obvious in my case. Does it make sense to you guys?
