Mine is on '05 (and my MPG is absolutely awful, see other postings on that - I have 7000 miles this 4x2 V6)
Concerning an offical TSB. I can't believe they don't know 'how' to fix it, wouldn't it be more accurate to say, they don't want to cough up the money to fix it! How can we force them to fix it, is the better question. Once it gets out of warranty you can be sure it will then soon 'need' to be fixed.
U-Joints (unlike CV) do not provide a constant angular velocity (rotational speed) output when deflected from the straight position, but instead, create a sinusoidal velocity profile as the shaft turns. If only 1 U joint were used, either the wheels would turn at varying rates or the engine would (if the system were perfectly rigid). However, if one Ujoint is deflected 5 degrees and another on the opposite end of the prop shaft is deflected -5degrees, the oscillations are 180 deg out of phase and cancel each other. This is why there are always 2 U joints and the tranny output shaft must be parallel to the differential input (although they can be offset). However, if you offset a section of the prop shaft in the horizontal plane, the alignment of the U-joints will not be correct and a component of oscillating angular velocity may remain. This will setup a torsional vibration, which can manifest itself in vibration of any number of parts of the vehicle. Each component of the truck has a natural frequency, and if the impulse of the vibration is near that natural frequency, it will have a tendency to resonate, the vibration only being attenuated by the damping in the system.
All this means that if that mid-prop-shaft bearing is not properly aligned, it can setup a vibration at a certain rpm range. If it is being communicated from the prop shaft/differential/axle/etc to the truck body, that vibration should be noticeable at a certain vehicle speed range. If being reflected back thru the tranny and engine, it may be somewhat independent of vehicle speed, and more related to engine rpm.
In any event, it's worth taking a look at the alignment of the prop shaft and bearing if you are experiencing the vibration problem.
Today I noticed that my right front mud flap was rubbing the tire. I got out, and it had ripped the section from the inside, all the way until the last couple inches of the outside, and that was all that was holding it on. Does that seem odd? I haven't changed the tires from stock, and haven't been off-roading or anything. Would the dealership cover something like this under warranty?
I got mine from dynolock.com. That was back when they were selling them for $25 shipped. Not sure what they are at now.
edit: Ouch! $35 now. http://dynolock.com/xcart/catalog/Toyota-Tacoma-2005
Maybe you can find them somewhere else for cheaper now.
The dealership should replace your mudflap but they can always accuse you of off-roading or extreme use. They are something like $80 new. I took mine off so if you, or anyone else, is interested speak up and I'll let them go for half that.
You couldn't see the poor quality BEFORE you installed it in the truck?
I would have returned the kit right off the bat. I sucks to hear that the kit is poor quality, as I was considering it myself.
I swung by the dealership yesterday, and the guys were more than happy to replace the flap. I assume that I'll probably have to remove at least the front ones, if I go with a slightly bigger tire when these wear out...but it's nice to know that I'll still have them, if I need them later.
Very easy, takes about 10 minutes but mainly because there are 20 screws in the tailgate you have to take out and put back in.
...Any advice on the Prerunner Double Cab?"
How safe?
If safety _is_ really a priority, bag the PreRunner and get the normal 2WD truck.
Why? With 4WD, you trade go-more-places for on-road handling and better mileage.
4x4's have slower slalom times and more propensity to flip during panic maneuvers. The higher ride height increases drag at highway speeds, reducing gas mileage. The "normal" 2wd's lower bed is also a tad easier to load than the 4x4 and PreRunner. The PreRunner trades the lower 2wd center of gravity and drag (which is still worse than most cars), and trades it for an "image", with none of the benefits of 4WD.
Last, but not least, Jeepers call it the "PoseRunner"
Good points but it won't do him any good.
havok, I noticed you mentioned problems with the 4x4's? I'm not sure what you're referring to but I assure you that any problems I'm aware of ('05 paint chipping, ticking, leaf spring squeak) apply to the Prerunners and 2x4's as well. There aren't any posted problems on here or on Toyota Nation that concern the 4x4 only.
I love my truck. I have a 4x4 access cab. No problems in just under a year. I have 14,000 on the odo.
Is that the PreRunner or standard 4X2?
Paint has been an issue for Toyota since they came to America in the 60's. Hasn't hurt their sales.
As for the PreRunner, it does have benefits over a regular 4X2 including better suspension for even minor offroading not requiring 4X4. Also has better clearance for off-roading as well as driving in snow. Nothing stops you quicker than high centering in snow. Also, as mentioned above, you gotta get atleast a PreRunner to get 4 doors. I just went over 10K on my 4X4 TRD O/R 4 door, and could not be much happier (a Tundra would do that). Pay a little more and get the 4X4.
Also, I prefer the outward visibility of the 4x4, or for that matter, the Prerunner.
Thanks,

Thanks for setting me straight. Maybe a Subaru or Volvo wagon with a 4x8 trailer?
BTW, also overheard in my local pub:
"PoorRunner"
"PreTender"
Don't shoot the mesenger! :sick:
It was pointed out to me that the Toyota puts the same TRD Off-Road decals that are on my 4x4 on the PreRunner, and the same guys were wondering if the Pre was the inspiration for the Ford 4x4 commercial a few years back. Remember "Is your off-road package just decals?..."
We all get along well, but it was a funny conversation.
I have noticed that when I am driving at speeds greater than 60 mph and I depress the clutch or shift into neutral (attempting to coast downhill), the engine does not reduce RPMs at all. If I am at 3500 RPM in 5th and I want to just coast down a long straight hill, I put it in neutral and the engine stays at 3500 RPMs. This will last until:
A) The vehicle slows to less than 60 MPH
or
This is annoying and kills my fuel economy. I live by a long steep grade mountain pass that is great for coasting on descent.
Does anyone else have this problem or know for sure if it is a new engine management control?
I informed Toyota that this shaft was unacceptable and I wanted it out ASAP. They complied and brought in another complete driveline. The second replacement arrived and it only had three small balance weights on it. Toyota installed it and after two tries managed to match the factory marks. I warned them about shifting the carrier bearing support so that it was centred to the driveline. What they did was centre it to the clearance hole and air impacted the bolts. This permanently dimpled the mountinig plate so that the carrieer bearing mount will not position anywhere else. This all translates to the carrier bearing being out of line with the driveshaft. The fact that the crossmember support for the carrier bearing will not allow for the carrier bearing to be properly centered is to say the least disturbing. As it stands now the latest driveline has two critical areas of speed in which you can feel vibration at 60 KPH and 105 KPH. After 2,000 Kilometers it is starting to shutter on the 1 / 2 shift at light to moderate throttle. Sometimes a light vibration is noticable on a heavier than normal takeaway from a stop sign.
The main questions are 1. Why is the carrier bearing not able to be directly inline with the driveshaft?(This is an absolute must!) Are the engine and transfercase out of position or is the crossmember positioning the carrier bearing factory flawed? 2. Is the rear differential misaligned? 3. Are the Dana Spicer slipyokes of such poor quality that even if good alignment is achieved this shuttering would still be an issue? 4. Are the leaf springs so mushy that shaft wrap is excessive?
Not very impressed Toyota, this is not how to become number "1".
I have requested a meeting with one of their factory engineers and I will settle for no one else. I will address all of the above questions. I will keep you informed.
Only out of my airplane, which happens to be a felony.
I lost 20 gallons of 100LL ($4.55/gal at the the time) last fall. Two other aircraft got hit during the same week at the same field. Cops attributed it to ricer racers.
Other than that, I haven't even seen it in my local Police Blotter columns.
I have a Stant locking gas cap on my truck. Not so much for preventing gas from coming out but more for preventing idiots from putting stuff in. Search "locking gas cap" and you'll find the part number.
I do believe I read a post that these trucks have a screen in the fill tube to prevent syphoning and also big chunks of debris from getting into the tank.
The bottom line in all of this rhetoric is that a driveline should be smooth and have no vibration what so ever. If there is any inherent resonation or vibration at any frequency all parts associated will have shorter than expected life spans. This translates directly to increased maintenance costs much sooner than need be. In Canada these vehicles cost us 41,000.00 plus 14.5% taxes. We've paid enough already and the drivelines should not vibrate or resonate, period!
The whole point of these discussions are to find the truth behind what is causing the driveline resonation that start developing after 3-4,000 Kilometers in the 1 / 2 shift patterns of these truck. Replace the entire driveline and the problem disapears, only to come back in due time. There could be more than one cause to all of this.
For my money I'm betting the causes are: 1. The relative positioning of the carrier bearing cross frame support, 2. the carrier bearing resilient mounting material is too weak, and 3. the inferior quality of the slipyoke spline.
Looks and drives great and managed a great out the door price on it( 19,870 - that includes tax, title, license).
I note the body does appear elevated with noticable large
wheel well gap between body and standard size tires.
Can you experts out there post links to sites that would definitely have "street" fender flares. Just need the black accents against the dark red color and to reduce the wheel well gap slightly. Thanks

Oil crude is $73 US a barrel today.
Tomorrow I pick up my Stant locking cap at the auto parts store. Stant makes caps to fit the '05 Access Cab. My cost $22US including sales tax.
My intuition has served me well over the years.
i saw the dyno sheet for this i will post it in a follow up. 305 rwhp 360 ftlbs, 7LBS boost.
URD seems to be really short on all the other information. short of price 4700! and lead time. estimated to be june.
Expensive though...
CarQuest Part No. 35072 for a '05 Access Cab. The store gave me a veteran discount. List $32. Sell $14 + tx. The pkg reads "Made by Stant".
Retrofit means losing the anti-loss cord which connects the Tacoma cap to the access door.
It works Great! only drawback is the "zit zit" sound that the DVD navigation diskdriver makes when in navigation mode. It may be annoying to some folks. But they also have harddisk navigation model AVN7000 (?) which probably won't have the "zit zit" noise issue.
my cost was $1300 +150 installation( Super Autobacs in Stanton,CA). I also had the rear view camera Eclipse BEC105 ($200) installed in the middle top of the rear license plate
Some dealers do have factory DVD NAV option for 05+ tacomas which are equivalent to Eclipse AVN5495. But cost is almost twice at $2500 (Elmore Toyota in Westminster,CA)
