*** This thread is for all TRD S/C owners. There is a definate problem that needs to be addressed as a TSB and not a "fix it as it breaks" policy. If you suffer a different issue, please post. This is not a discussion thread, but a research tool.***
In speaking with a "soon to be authorized" TRD S/C mod/repair facility, the owner stated that the TRD supplied horseshoe brackets are the cause of all the TRD woes; from the broken mounting bracket, the blown end seal, and the worn shaft end bearings, to the complete failure of the torque shaft. It causes a misalignment of the torque shaft that creates undue stresses. This is a design flaw that should be addressed. I have been expecting an e-mail from that company listing their out-of-warranty repairs and update mods. So far, the pricing ain't too pretty.
From what I can tell, the 2008 and up S/C's were redesigned to fix these flaws. This would explain the delay in offering for the '08 models. Vortech lays the blame squarely on TRD as the pulley torque shaft tube is soley their design. Of course, TRD wants to push it on Vortech.
To better serve our TRD S/C members, I am going to create a thread in the Knowledge Base section to track these issues. If there is enough commonality in the problems, then we can address these directly to Toyota Corporate to offer a TSB to update all previous year models to the better and safer design. Why should we have to pay good money to fix TRD's engineering flaws? We will need the proof so post up only if the problem was yours.
