Driveline vibration Tsb out

Whereabouts would I feel the driveline vibe?

Occasionally I get one on deceleration at about 10-20..just got the truck in October.

 

Just for others to reference:

Mine does not vibe under any type of "normal" accelerating conditions. However, if I really step on from a stop (not enough to burn rubber but pretty close) then I'll get a very very bad shudder during this speed. It will shake the steering wheel and the entire cab will vibe. Its pretty loud too. I can feel it in the peddle and seat as well. It sounds like a wheel is about to fall off but like I said, this is only when I really gun it like hard enough to redline in first gear. Under normal accelerating conditions (which is about 99.9% of the time) then no shudder.

I should also note I am lifted (1.75") up front with 5100's and have the tsb pack in rear. Stock coils, spindles, uppers, lowers, etc. Only new shocks. Running 265/70/17 BFG AT tires on aftermarket rims, but had the shudder both before and after any modifications of suspension or wheels and tires.

I dropped 1", but I have Dakars with AAL and a shackle flip. About 5" of rear lift total. You may need less.

Best is to get several spacer sizes and dial it in.

Regear was something like $1600 turnkey. If I had a place to tear the truck apart for a couple days to do the swap myself it woulda been like $1200 without diff swap labor.

 

Good ol Toyota quality

I got so many TSB's that "could" of been covered it's a joke. List of issues with these trucks just gets longer and longer.

At least none of us should have to worry that long. After all, our frames will be completely rusted out in a few years anyway.

 

Does anyone have the full write up for this TSB yet? This thread is getting full of the same shit the other 100 vibe threads have in them.

So looking through it, it's all the same part #s as before but they combined everything together into one TSB. I already have the TSB 4-leaf packs and TSB rear transmission mount. Looks like I'll order the steering wheel damper and install that too (although I have no idea what that is/does), then I'll be fully TSB compliant.

 

It appears this bulletin doesn't cover the 6spd manual trucks... im a little disappointed...

 

Nor the 5 speeds.

 

Where are you all finding this information? I looked online and on my Toyota Owners website and nothing comes up.

Part numbers for the harsh ride tsb springs are different.
So I have the mount ordered and should be here tomorrow so my next week I
Ill be able to see if it helps. Need to find some info between the two spring sets

 

Well I'll be taking the truck in asap. Tranny mount will be covered since under power train warranty, I already have tsb leaf pack, and the steering dampener is such a small tiny piece it can't possibly cost more than about $20 so I'll just order that and screw it on myself. Its literally 2 screws and your done.

 

Hmm. For the part #s it says "same" as the previous #s. Am I missing something?

 

You need to read the harsh ride tsb part numbers. They don't distinguish if you have the harsh ride tsb done or not. Kinda confusing it's not more complete than what it is. The part numbers are not the same as the harsh ride ones.

 

The new rear springs are the interesting item within this TSB, like Tacomamike said we need to try and dig up some more info on those.

 

Okay, thank you. I guess I have the "harsh ride" springs. I had the 4-leaf packs installed in early '09 just before my truck went out of the 3 year/36k mile warranty. It was for the "easily bottomed-out suspension" when carrying even light loads.

Sorry for the continual questions, but what's the difference between the two different leaf spring TSBs?

 

I don't know. Like i said the two spring numbers are different. It would be nice to know the makeup of the two spring sets IE stiffer, spring arc, composition.
I'm very hesitant to go backwards in my spring rate if that is the case but I really don't think that is the situation. When I get ahold of the rep maybe he will give me some more info. Time will tell.

 

Once again, thank you good sir! It's so cool to have expert resources like you and others around this site. Will be standing by to see more info as it becomes available!

 

Thank you.
Nice of you to say.

 

I'm dropping the truck off next week to have it all done. I'll update when I get it back.
