TSB or non-tsb

how do i know if i need a TSB AAL or non-tsb and whats the difference?

 

i have a 2007 tacoma 4x4 accesscab

 

The toytec AAL should fit both. Or just look under your truck.

 

The difference is: with the TSB AAL, the truck can handle more weight without bottoming out, handles better and feels more solid with the extra leaf. And it adds about 1 1/2 inches of lift in the rear.

 

Didn't want to start a new post since ther are a number of them on the subject already but what approach did some of you take as far as getting the tsb for rear leafs done? Did you call the dealer and make an appointment? What did you tell them the problem was?

Or did you call or e-mail toyota directly? I have an 09 TRD Sport 4x4. The springs have the same part numbers as the tsb.

 

Have any of you who had the rear spring tab done experienced the low speed shimmy afterwards? I installed a Alacan aal on my 06 tacoma along with the shims which raised the rear 2.5" and had a shimmy with that.

 

stupid question, whats TSB?

 

Technical Service Bulletin. There are never stupid questions.

 

Not a stupid question. TSB stands for Toyota Service Bulletin.

Not a recall, only a response to problems customers are having with their vehicles.

 

You only need it if you are experiencing problems carrying a normal load up to the capacity of the truck. Excessive bump stop contact, for example.

 

Check out this link for how others got their TSB AAL approved.

How I got the TSB on my 2009

 

Aside from the part numbers is there a noticable difference between the old parts and the new parts they install for the TSB? I am dropping my truck off tomorrow and I want to know what to look for when it's done. Not that I don't trust the dealership, you just gotta "c.y.a." sometimes.

 

Here are some pix for ya. CHeck part numbers for reference. The most obvious is that you now have 3 leaf springs, and with the TSB AAL(add-a-leaf) you will have 4

 

Did they replace your shocks as well?

 

Oh yeah... I forgot about that part of the TSB. Since I have the TRD Off Road, I already have the upgraded shocks.
Only non TRD's get upgraded with Toyota Factory Billsteins with the TSB.

 

I have a 2009 Tacoma 4X4 DoubleCab. I use it to two a 21' travel trailer that has a dry weight of 3600 lbs. I am trying to get the rear leaf spring TSB done to stiffen up the rear end. I talked to the dealer who was clueless about the TSB so I printed it and showed it to them. This did not work. They siad they have no authority to do the TSB and claim to have spoken to the district rep who said the TSB cannot be done to the 2009.

In our conversation the dealer claims that the TSB has already been applied to the 2009 Tacomas. My Tacoma which included the sport suspension has a 3 leaf spring set - two full leaf springs and a third short (helper spring). The dealer claims that pre-2009 Tacomas only had a 2 leaf spring set - two full leafs and no helper spring. Discussions on this site lead me to believe that getting the TSB done would result in a 4 leaf set - 3 full leaf springs and 1 help spring.

Is my understanding correct? How many leaf springs did the 2008 Tacoma have compared to the 2009 Tacoma?

 

Had mine done a few weeks ago.. Just told service manager that while hauling a load the truck felt very mushy (technical term) and bottomed a few times. Other than that, no questions asked.

Non-TRD Pre-runner DBL Cab Taco...got the Bilsteins (all four) and a new leaf spring pack, not just an added lead.

Hope this helps.

 

Your dealer is giving you a line of bull, however he is correct in saying the TSB DOES NOT cover the 09's (Yet) keep your fingers crossed, call toyota corp and file a case number ..this may help...search other threads on hear for some hints!
