Add a leaf help.

oh I see...I stand corrected. If it is truly a 1 leaf AAL, then I suppose maybe it's the wrong one.

Chris, if I cut mine off... do you know if I'll be able to put a new retaining clip on at some point (again, if i sell my truck in the future and go back to stock)?

 

after doing a small search, I believe the OP is in canada..
that is probably why he didn't know he has the tsb-version to start off with..

dang... It feels awesome to have (hopefully) solved someones problem after all the help I have gotten in the past...

 

Just to clarify my rear leafs consist of an overload, small lower, middle and the main. It's a three leaf pack plus an overload.

 

Here is the order of my install.

---------Main top Leaf----------
.......-----Middle Leaf-----
.........\..................../
..........-Add -a- Leaf-
..........---lower leaf---
............--overload--

 

what is the part number of the leaf you ordered?

 

op.. You have the tsb which came as stock on tacomas in canada.
usually stock tacomas have 3 total leaves... You have 4. There are 2 different aals from toytec. A non-tsb 2" model, and a 1.5" tsb model. When you ordered, did you specify you had the 4-leaf pack?

 

On my bill I was charged for a tac-al-ha. I need to find my packing slip and need to find it to see what was actually sent.

 

well someone is right... the TAC-AL-HA is for the 2" lift and I should have had the TAC-AL-TSB 1.5".....

its on and installed and with having them to be returned and reshipped to Alberta Canada, is there issues with running this set up now, What are the failure points with having this add-a-leaf inside my leaf pack instead of below it. (excluding the overload leaf).... As well as the larger leaf lift.... shimming issues, driveline angles.... or even load capacity with the add a leaf between the lower and the middle leaf....

Oh Hum... Crap...

 

i wouldnt run it...

 

I don't think anyone could tell you with 100% certainty what the issues would be. I think running it you would be the test case and you would be telling us what problems it may/does/did end up causing..

If the difference between the tsb and non-tsb was just the additional bottom leaf (not your overload), then in essence you could just take off that leaf and leave your 2" aal. Would be nice, but I highly doubt that the only difference between the tsb and non tsb is that leaf above the overload.

Here are the 2 problems I see with running it the way you have now.
1. You probably have close to 3-3.5" of lift right now. The 4 leaf set is already higher than the 3 pack. That is why toytec made a aal specifically for the 4 leaf set.
2. You "may" be negating the true benefit if having the 4 leaf pack having the aal below the first 2 leaves. The aal's arch, or over-arch is designed to push up and support the leaves above. Hence, the aal in your install is pushing up on only 2 leaves rather than the full 3 that the 1.5" aal is designed to do. That would leave the question... How much support or weight is your 3rd leaf actually doing if a majority of the weight will be taken up by the aal (in the way that you currently have it installed).

 

Now this is good stuff. Thanks everyone for the input. So the question remains, what shall I do now. Well I'll call toytec and see what they will do, and get them to voice their concerns. But totally agree with "raycie". I think that I need to go to the mall and park beside a stock truck and take some measurements, just to see what we are exactly working with.

Thanks again and please continue to discuss this for me.

If anyone in calgary has and ultimate set up with an add a leaf I'd love you to drive my truck to see how or if the ride quality in the rear has been impacted.

 

OP.. after I posted last night I did start to think about "failure" points.. I wondered where your 3rd leaf is touching on your installed aal..

Take a pic and post..

I started wondering if the AAL could fail, or if your 3rd leaf could fail. The AALs do not have any stress given to the underside of the leaf (other than when a it would touch the overload and then then AAL would be completely flat - something it is never supposed to do..)

I did read someone in another thread recommend to just take out the 3rd leaf and replace with the 2" AAL, but I doubt toyota would replace a $1200 leaf pack if they could just have their techs install their AAL and make it a 4 pack..

Just be smart with your $20+,000 truck.. and air on the side of caution....
