Rear Spring & Tailgate TSB Quick Reference

[jonl9]

Another new member here who is grateful for the information in these forums. I printed out the suspension TSB and brought it to my dealer. I explained I haul a 4,000 camper, and...the parts are on order!

Thank you!

Just noticed this thread as a sticky, so I'll put my reference thread in here so I won't have to retype the info time and time again.
Read this thread for some Rear spring TSB help>>http://www.tacomaworld.com/forum/2nd...-leaf-tsb.html

I have on 07 with about 32,000 miles on it. I recently started hauling my sportbike in the rear and haven't had any bend yet. I plan on getting a heavier bike and am worried about bending the tailgate out of warranty. How did everyone else bend their tail gates, any pictures?

so are these tsbs, also available in canada??? Everyone I seemed to notice were from the states that were getting this, and if I can hook into them here then I'm all for it.

Hey I tried calling the toyota severice number but all they did for me was tell me to talk to my service manager at the dealership... I have a trip in in a half hour so we shall see... btw, I did notice some bottoming out in my truck bringing loads of wood (deck), crushed stone, and even bringing home some laminite flooring. I hope I fit in that description.

Haven't seen this addressed in any of the other threads, so I'll ask here.

I'll note here that I didn't get any questions from the dealer when I asked to get the TSB implemented. I mentioned that I had a problem and had called Toyota and that the Toyota rep suggested I get the TSB. They ordered the parts, got them in two days and called me for an appt to get the TSB done. Nothing to it. Nice. San Marcos Toyota in San Marcos, TX.

I had the spring TSB done today. Before taking the truck in, I measured the ride height directly over the wheels. I measured from the ground to the lower edge of the fenders. When I got the truck back today, I measured again.

all with no load
front - 34 5/8 >> 35 1/8
rear - 37 >> 38

So, a 1/2 inch increase in the front and a 1 inch increase in the rear.

So, that leads to my question (sort of). I understand, with the new leafs in the back that the height could change. An inch seems a bit much. Why would they raise the ride height with the new springs? It seem it would be simple enough to arch the new springs to give the same no load ride height, but they didn't.

Then, I know they changed the shocks in front. As far as I know they did not change the springs. Since shocks have nothing to do with ride height, why did the front go up at all? Also, does anyone know how they raised the front?

Thanks for any and all replies!

[br217398]

well for the front you are correct about shocks not adding ride height and springs not being changed. However with a more heavy duty shock, it wont compress as easily under the weight, which in turn raises the ride height.

With the rear, so much height is added due to another leaf in the rear.

hope i help out a bit.

EDIT: typo fixed......

Thanks. I don't think the front springs were changed, just the shocks. That's why I can't figure out the change in height.

haha jk jk ignore my last message.... its a more heavy duty shock not spring...... so changing the shock allows the spring to not compress as easily

So, is the shock gas charged or something, such that is gives some lift?

Hello everyone! This forum kicks ass! A great source of information to say the least!

Anyway, on subj... I'm scheduled to have the suspension TSB done this Friday. The two guy with the PHD's at the service desk were practically trying to talk me out of it. I don't get it. I told them I have not even towed my RV with the taco yet and it's been bottoming out with just my 16' utility. Loaded to brim, of course... They kept going on about how "your not going to like the ride anymore" and "It's going to be stiff and you'll feel every little bump in the road". Well, I said I bought a truck to tow crap! And, I'm not waiting around until my warranty expires to realize I gotta have it done. They also said that people were coming back complaining about the ride quality after incorporating the TSB. I got no clue! If I want my truck to ride like my car, I'll just drive my car...

So, can anyone tell me about this bad ride after the TSB?

Thanks and keep those post full of great info rolling in!

Yeah, it rides like a good truck after the TSB is done, instead of the soft Toyota car ride it has when stock. I think it is great. The truck is much firmer, but not rough, still very comfortable. It handles so much better! There is no reason not to do it!

[tacotexan]

This is what I thought. I'm on my way to get it done this AM. I'll let you all know how it went. Thanks!

Side note... For those that had the dealer do the tsb wrong, what was it I should be looking for? Or, what was it they did wrong on yours?

Later!

[tacotexan]

Yep, just as suspected... A great ride. Get it done.

[jonl9]

TT, the ride will be noticably firmer, but in no way jarring at all. You will notice quite a difference in towing your RV, it really stablizes the whole rig and you'll get much less feedback in the truck from the trailer than before. The ride while towing is more comfortable than before the TSB, we found.

Good luck!

Jon

[tacotexan]

I'm not having a bit of regret over having the TSB completed. Everything is smooth. I will give feedback on the rv towing experience, asap. Thanks!

I just bought a 06 4x4 access cab on the 8th. It had 35500 something on it, in two weeks I had to drive a lot and now it is 36500 something. I got bumper to bumper and the Toyota certified warranty. I noticed about a week ago really bad squeaking and it started driving like my poor little ruff riding 98 tacoma I traded in. Is this what that TSB is for?

[Tio Pepe]

Hola, Taco Heads!

This is my first post, though I have been lurking here for awhile doing some research. I pick up my 2009 Tacoma next week. Whats the deal on these TSB's for the 2009's ? Particularly the rear leaf spring. Have they been fixed for 09's ?

I was likely going to do an aftermarket lift kit, but I may get this done first if I get new Bilstein shocks out of the deal. Especially since i just went with SR5 package plus TRD supercharger,intake, and exhaust.
