Toyota Tundra Forum

Sky sent me this new TSB to share with all of you. You'll notice the date of it is June 30 and it adresses the Front Differential Growl/Howl/Rumble Noise at 15-30 MPH. http://toyotatundraforum.com/pdf/Front Diff TSB.pdf

'10 CM SR5 4x2, S.A. Built & Purchased Sept '09, 5.7L, Sandy Beach Metallic, Drug Information in Lay Language

Bought my tundra mid-July as of November 28 I have almost 19k kms. The front end started making 'growling' noises pre-10k kms, finally got the truck into a local dealer. They had the truck for about 1/2 hr, took it for a test drive and told me they would have to replace the front diff ...
Ok fine, its under warranty, lets get it done.
Turns out Toyota has 30 front diffs on back order and as of today they wont be releasing any until Jan. 09 ...
A whole month w/o 4x4 in Canadas winter, give me a break .. Thanks alot Toyota ...

It seemed like the local dealer didnt know anything about this Service Bulletin either... what a joke ... So i phoned the dealer I bought the truck from and so far they're great! Looking into it much more than this local dealer ...

Thought Id share my story incase anyone else is having the same issues ... If you are get on it!!! Email Toyota so they may get thier a**es in gear too! I am!

Hey Meaney,

I just had my front diff replaced this week. I called Toyota Canada to complain about all the problems I had with my Tundra and basically the operator at the other end told me tough luck! I went one step further and somehow got in touch with a VP and she moved me to the top of the list to receive diff sooner then late January. They also arranged a rental truck for me (dodge ram) what a piece! Anyways.... my advice to you is keep calling Toyota Canada and complain as much as possible. I threatened to default on my lease payments and simply walk away from this truck! They didn't want to hear that!

Good luck with your diff replacement, I certainly know how your feeling!

Won Lemon Law arbitration - front differential

"The NCDS (National Center for Dispute Settlement) arbitrator awarded me a replacement of my O7 4WD CM limited because of my faulty front differential. I'd like to make you all aware of my experience in case you might be dealing with the same front differential problem, or if you might have to go through this process for any other problem.

Some of you might be familiar with the problem brought up by Seadragon and others - the cyclical, growling noise from the front diff that appears between 10 -30 mph upon returning to 2WD after using 4WD (search humming, "wu wu" and/or front differential). I'll leave it to you to read and distill the various experiences, but what "my" Toyota Field Specialist says is that a collar in the front differential is not sliding back into place once disengaging 4WD. The creates the noise, vibration that can be felt through the steering column, and can wear front differential parts, especially the front drive shaft. The collar can slip into place sporadically or if one switches back and forth between 2 and 4WD, which has been people's experience.

Toyota seems to have acknowledged the design flaw of the first production run, has a new front differential design for 2008 apparently and has issued a TSB to replace the affected 07 AND 08 front differential. It's interesting that Consumer Reports differentiated between the 2 and 4WD versions of this truck when it was being released....

I'll detail my service experience to illustrate Toyota's Dispute Settlement Program (The process was in my owners manual packet - I gather it varies state to state, but I had to send a form letter and a copy of my service reciepts and any other documentation to the NCDS):

6131mi - Replaced front differential fluid (3 days in shop)
9800mi - Replaced front differential (4 days in shop)
10690mi - No repairs done - I "was imagining the noise" (1 day)
15508mi - Replaced drivers side front wheel bearing (3 days)

I then initiated contact with the Toyota Customer Experience Center notiying them that "I expect them to replace the vehicle pursuant to 6.07(c) of the Texas Motor Vehicle Commission Code". In this time, we played phone tag between me, them and my local service manager (their policy is to not leave nor take messages). It was the biggest farce; 2 weeks would pass at a time to communicate a sentence. I live 1/2mi from my dealer/service bay and had to talk to them through ?California? I kept a dated hand written log of our phone conversations which the NCDS arbitrator took particular interest in.

20631mi - Replaced front differential - TSB 0121-08 (10 days)

Since then, the original noise and vibration has gone, but I get an incredible crunching and shuddering from the front within 10 yards of using 4LO ( straight line in the dirt, of course). It seems like some kind of gear mismatch...???

28,500mi - NCDS hearing in local service manager's office between me, arbitrator and Toyota Motor Sales rep & Toyota Field Technical Specialist (both on speakerphone)
29,000mi - Replacement awarded - mileage charge which will probably come to $5-6K

I'm satisfied with the outcome, although I do believe if I had made a spreadsheet (like I did after the hearing) that clearly illustrated dates, mileage and nature of service, how long the truck was out of my hands, etc, and made a demand that I have the vehicle replaced and only have to pay for the first 6131mi, I might have had a more favorable award....

It might be the lack of time/tenacity that I did not find much info on the replacement process - maybe the lack of experience with this process on this board - who knows?

I would sure like to hear your thoughts, especially on what I should expect from here (Toyota Motor Sales, USA is supposed to contact me) and how I should handle it. Do I have the opportunity to adjust the mileage cost? Can I push for an 09, or settle for an 08? What do I do about my aftermarket items - can I make Toyota buy them?"

brought my truck in this morning armed with a copy of TSB 121-08. I also asked to have my brakes checked since intermittently I feel a vibration when stopping.
3 hours after bringing it in service advisor called, went back to dealership, new rotors and brakes no charge and all parts ordered for front end.
Competition Toyota, Middle Island N.Y. Excellent customer service.

Good to hear they took care of you.

Also welcome to the site. Introduce yourself and tells about yourself and truck on the new member page when you have time.

Good for you I had same problem (Worped rotors) at 15,000 miles. Took it to the dealer 2 weeks ago (New Jersey) and they machined the rotors and left me with same pads.
after sending them email and a bad servey. they called me and told me that they have to go by Toyota repair guide lines. )(&)(&*.
o yeah and took it 3 times already regarding a wheel alighnment. truck keeps puling to the left at highway speeds and steering wheel turns left when breaking at low speeds. they keep teling me they cannot replicate it. so i told them from now on i will not leave until they testdrive the truck with me in it.
These people realy think that all the costumers are brain dead and that we dont know anything about the vehicles we own. i can do anything on my vehicles but rebild the engines. the reason i got a new truck and platinum warranty is so that i dont have to do anything to it myself.

Thanks,
