Have the much discussed "Vibration between 55-65mph" issue? I do, and over the last two months I have done everything possible to help guide my dealership through the issue from what I have read on here and online everywhere. Toyota has an issue here (non safety issue IMO), but it is an issue. My truck is a 2010 Toyota Tacoma TRD Offroad 2WD with 25k miles on it. Here is what I have had done/did myself to it since I purchased it:
* Harsh Ride TSB (replaced rear leaf springs)
* Installed Bilstein 5100's with front set at 1.75"
My vibration occurs at between 57-62 mph while on load, but tends to go away after I let off the gas. Some days its loud, some days its quiet (but certainly there).
Time to bring everyone up to speed on my dealership visits the last two weeks. Now, before I go into it, my dealership is GREAT and the people I have been working with are doing everything possible to accommodate this situation. They have offered me two different rentals, but here is here what they have done so far:
1. First thing they did was order and replace the driveshaft. I am assuming this is new u-joints and carrier bearings as well, but I will need to verify. This did not resolve the issue
2. They then tried the suggested shimming/angle changing of the driveshaft that was suggested in another thread. They had to buy the tool and order the shims, but were willing to try this if it had in fact worked for a user on here. This too did not resolve the issue.
3. At this point, they wanted to point to the Bilstein 5100's that I had put on. I had set the front to 1.75", but this was only to level out the front from the rear due to the rear leaf spring TSB. I explained to them that there was no way it could be this because the noise was there before I put these on, it just wasn't that bad then. I and they suggested two things:
A. I suggested setting my front 5100's to the lowest settings and put it back to stock height. This didn't work
B. They suggested throwing on a new set of stock Bilstein's. I even told them that if this was the problem, I would gladly purchase the set from them, but I knew full well the shocks were not the problem. This didn't work either.
After all of this had been tried, I was told they would be contacting Toyota directly for the next steps. Shortly after, I received a call from the service manager who said they had just ordered a brand new transmission and would be replacing this next week. This whole time I had been suggesting to them that I thought it was the trans, due to the fact that when I reached the "speeds" that the vibration would occur in OD, I would throw it down to 4th gear and the vibration went away. When they said they were replacing the whole trans, I asked if they had even opened it up to see what the issue might actually be. They just said it would be easier to replace the whole thing. Then he told me what Toyota was going to be paying them for all the work, and it was nearly as much as I bought the truck brand new for. Now, I don't know how this is so, but at which point does Toyota admit they have an issue on these trucks and do something more than just replace, replace and replace. When does lemon-law come into affect? Now again, I am blessed that this dealership is going the extra mile to get my issues taken care of, but I also feel horrible that it is costing so much money on Toyota's end.
Now I am waiting on the new trans to come in. My question here I am wondering if the trans will actually be brand new or a refurbished. Anyone know how this all works?
Does any of these make sense to the mechanics out there? I have started a poll to see whether or not you have the vibration or not. I figure we should start a sticky or something on this as it seems to be a very wide spread issue. I will certainly update everyone after then new tranny is installed and I get my new Firestone Destination AT's put on.
5/23 Well, my truck goes in for a new tranny tomorrow evening and will be purchasing a new set of Firestone Destination AT's while I am at it.
5/24 Truck dropped off today. Get it back tomorrow it looks like. Will update all then.
5/25 To top all of this off, I had a rental from Toyota (Corolla). It took damage in the very large (baseball size) hail that the DFW area had lastnight. Now I am responsible for the damage, but the dealership has my truck on the lift and can't verify whether I have damage or not (since the same storm hit the dealership too).
5/26 Went to the dealership to pickup my truck. Spent $720 on new tires as well. Sat and talked with the rental department about insurance and apparently I am responsible for both (hail damage on the rental while at my home, and hail damage to my truck while it was at the dealership). Sat and talked with the service manager (who I do really like) and he said he personally drove it and said the vibration was gone.Guess what?
STILL A VIBRATION....and almost more noticeable than before. It now extends between 55-62mph, but anything before and after those speeds it is just fine!
Now it's time to speak with Toyota directly. Who exactly do I contact?5/31 Rode with the mechanic and service manager. They both felt it and heard it. Strangely enough, the noise and vibration were much louder when I was the only one in the vehicle. Put three grown men in it and its there, but a little quieter (still very noticeable).
Was told they plan to fix it, but have to speak to "technical" about it first. They also wanted to test drive 3 random new Tacoma's and see if the same happens. Not sure what that will prove to them.....
6/3 Vibration getting worse. It now occurs between 50 and 65mph, both when I give it gas and let off the gas.
6/7 Dropped my truck off early today. The plan was to pull a rear differential from a vehicle they had in stock there, put it on my truck and see if the vibration goes away.
6/8 Dealership pulled a rear end from a 2011 Tacoma TRD new on the lot and replaced it with mine. Vibration is gone!!!!!! I still think it was something as simple as the pinion bearing, but they didn't just check that. Oh well... (25K miles)
8/5 DAMNIT! The problem has returned. Vibration and very rough ride at the same speeds. Feel like the truck has 200k miles on it when I drive at these speeds. I notified the same dealership last week. WHAT ARE MY OPTIONS?!
