I have a 07 Tacoma TRD Off-Road and called the Toyota dealer in Columbia, SC. I told him about the rear being soft and that the ride was harsh. The service guy asked me what I was hauling to make the rear bottom-out. He actually got a little pissy with me at first. I told him about the TSB and that the rear leaf spring replacement also helped the overall handling and ride of vehicle. He said that he thought that was true and that the dealership had performed several "fixes" regarding SU006-07. I said that due to the handling, hauling, and towing improvements that I wanted to have the TSB performed on my truck. He said that I needed to bring it in so that they could have a look at it. I hope that this is not going to be a fight.
By the way, I have read that some of the 07's actually came with the improved leaf springs. Is this correct? Because if it is true then that would be another argument to use to get the problem corrected. I mean if Toyota saw the need to change the leaf springs in the later models that came off the assembly line, then wouldn't it make since to assume that the engineers thought it was a problem?
Also, I have noticed a few of the members here are in SC, has any one successfully had this completed without a major hassle?
Thanks in advance for your help.
