8 DAYS LATER, NO "FIX"
I got my truck back yesterday, after the dealership had it for 8 days.
The service rep I spoke to on Tuesday told me that, after my driveshaft came back from being tested by their specialist, the dealership wasn't happy with it, and that Toyota told them to order and install a new one.
Yesterday (Wednesday) around lunchtime I got a call from the service technician (not the rep) to say that the truck was finished and ready to go. I was surprised that the call came so early in the day, given what I was told on Tuesday.
It turns out that the service rep had misinterpreted what she read on her computer screen. What she should have told me was that IF the specialist found a problem with the driveshaft, THEN they would order a new one.
I might add that the service rep wasn't on top of her game at all. I hadn't heard from the dealership since Friday, so I called on Tuesday afternoon and supposedly caught her off guard (she was out sick on Monday). She read--incorrectly--what was on her computer screen. Had someone been giving me daily updates, like they did last week, that might not have happened.
Anyway, the dealership and Toyota were satisfied with the results of the specialist's tests on the driveshaft, and they reinstalled it in my truck. For those of you who might understand this crap, here's the description of the of the specialist's findings: (This is a direct quote from the paperwork, and it was written in all capital letters)
"FRONT SHAFT OUT .016 @ TUBE YOKE, MIDDLE TUBE OUT .003, CARRIER BEARING OUT .001 REAR SHAFT TUBE YOKE OUT .005, MIDDLE TUBE OUT .015, REAR TUBE YOKE OUT . 005."
I take the word "out" to mean "out of alignment" ?? If anyone knows anything about this, I'd appreciate a translation.
The Tech said that these numbers were all within acceptable tolerances. Therefore, Toyota would not authorize replacing the driveshaft.
So, at this point they've done everything they know to do. Short of Toyota redesigning the powertrain to eliminate the problem, there's nothing else they can/will do at this point.
Oh, by the way--one of the fixes on the TSB was to replace the leaf springs. When they did this, the vibration worsened. So in the end, they put the original leaf springs back.
I've been assured that Toyota has full documentation of this whole mess, and that if/when they come up with another "fix" they'll let me know. Yeah, just like they let me know about the current TSB!! I found out about it here on TW and had to call them. I know--it's not a "recall," so they were under no obligation to tell me. But still, they'd had my truck in once before (for 3 days) to mess around with the issue, so they were well aware that I would be eligible for the "fix."
So, I have a brand new truck with under 4,000 miles on it that I'm extremely disappointed with. It definitely takes away all the fun of having a new vehicle. My main concern is that over time this issue will cause undue wear and tear on the drivetrain, and diminish the overall value of the truck. I sold my '03 Tundra for 8 grand when I bought the Taco, and I was very happy with the resale value. I'm not so sure I'll have that to look forward to with the Taco in another 10 years. :-(
